Can Artificial Intelligence Help To Detect and Predict Early Childhood Tooth Decay?
4Aug
A recent review has sought to find out how effective Artificial Intelligence (AI) is in terms of detecting and predicting early childhood tooth decay. With oral health being crucial in children, spotting and treating problems is very important. Therefore, having advanced technology to assist dentists can be very helpful.

Artificial Intelligence (AI) is having a significant impact on a huge array of industries. The field of oral healthcare is no different, with AI having an ever-increasing role.

Now, a review of 21 existing studies suggests that AI has a strong potential for detecting and predicting early childhood tooth decay [1].

As strong oral health in childhood can lay the groundwork for a lifetime of positive oral health, being able to predict problems in children can be very helpful.

Background

The research focused on existing studies. One of the main focuses of the review was early childhood tooth decay, which is a serious problem.

Recent research found that in the United States, 29% of children aged 1-17 had received treatment for tooth decay within the previous year [2].

The same research also highlighted concerns over the oral hygiene routine of many children. For example, the research found only 3 in 5 children brush their teeth twice a day [2].

Poor oral health in youth can result in a lifetime of oral health problems. Therefore, avoiding such problems is very important.

Meanwhile, the research also involved analyzing the use of AI in dentistry. There is a strong expectation that AI will become increasingly involved in oral health over the next few years.

The Research

The research was carried out by a team from Newcastle University in the United Kingdom. Their work has been published in the Evidence-Based Dentistry journal – part of Nature [1].

The research team carried out a review of 21 studies that had been conducted between 2014 and 2024 [1]. These studies were oral health-focused and involved AI.

The research team were interested in both detection and prediction of early childhood tooth decay. Both are key parts of dentistry and is a crucial area for AI to be accurate with.

Detection refers to when AI can identify tooth decay. Meanwhile, prediction refers to AI’s ability to accurately predict future cases of tooth decay.

The researchers were particularly interested in deep learning algorithms. Deep learning algorithms use vast networks of raw data to analyze, review, and learn. They can then produce organized data and advanced insights.

This process was followed, resulting in the researchers being able to make conclusions based on the analysis of the 21 existing studies [1].

The researchers concluded that AI was capable of detecting and predicting tooth decay in early childhood at an impressive rate [1].

Moreover, the researchers noted that their findings suggested that deep learning algorithms were particularly effective at both detection and prediction [1].

They noticed that deep learning algorithms could detect early childhood tooth decay with an accuracy between 78 and 86 percent [1].

For prediction of early childhood tooth decay, accuracy ranged from 60 to 100 percent [1]. While this is a large range, the various studies produced mixed results. But with accuracy at 100% in one study, it underlines its potential effectiveness at prediction.

Overall, AI produced impressive findings, with strong results in detecting and predicting tooth decay.

The future

The researchers were very impressed with deep learning algorithms and their ability to both detect and predict tooth decay [1]. Therefore, the research produced promising findings.

The hope is that AI will be able to be used in the future to assist with detection and prediction of oral health problems.

When detected early, this would enable treatment to take place as soon as possible. The sooner treatment takes place, the smaller the chance of complications.

Similarly, if dentists had AI highlighting predictions of tooth decay for certain patients, it could enable them to suggest an enhanced brushing schedule, or more frequent dental visits.

Both of these could result in quicker treatments and improved patient experiences. Therefore, AI can offer a range of benefits.

The authors have cautioned that additional research is needed in order to improve the technology further [1]. However, benefits are already visible.

Thinking points…

[1] We mentioned above about the importance of early detection of dental problems. Therefore, it is important to see your dentist regularly! Attending a dental check-up at least once every six months is very important, as a dentist will be able to keep track of your oral health and spot any problems. We recommend that you book an appointment right away!

[2] As shown above, there are many concerns about tooth decay in children. If you have children, make sure you take them to the dentist regularly. This can get them into good habits for life and protect both their physical and oral health. You could also get them to go to the dentist with you – as this can set a good example for them to follow.

What Impact Do Antipsychotics Have on Oral Health?
27Jul
Antipsychotics are a class of medicines that are commonly used by people worldwide. They typically provide relief from severe mental health conditions. However, they are also associated with many side effects. Amongst these is poor oral health. Now, a research team has analyzed this connection in detail.

Antipsychotics are a group of medicines that are taken daily by millions of people around the world.

While they can have a positive impact on lessening the psychiatric symptoms of various mental health conditions, there are also some negative side effects.

Once such side effect is their connection to poor oral health. Now, a research team have carried out an analysis to explore this connection further [1].

About Antipsychotics

There are a range of medicines that fall under the class of antipsychotics. They are also known as neuroleptics or major tranquilizers.

Antipsychotics are used to treat mental health conditions. For example, Schizophrenia, Schizoaffective Disorder, and Bipolar Disorder all commonly involve antipsychotics [2].

Research suggests that approximately 3.8 million American adults were taking antipsychotics in 2020 – representing 1.6% of the adult population [3].

Antipsychotics are intended to treat the psychiatric symptoms of these conditions – such as hallucinations, delusions, and disturbed thoughts [2].

There are many different antipsychotics. The most well-known include Haloperidol, Aripiprazole, Lurasidone, and Quetiapine.

Unfortunately, antipsychotic use is associated with a range of side effects. Weight gain, dizziness, dry mouth, blurred vision, nausea, tremors, and sexual dysfunction are all common [2].

A situation often occurs where people have to prioritize their mental health at a cost of these side effects. Aside from the above side effects, there is also the connection with poor oral health.

The Research

The research was carried out by a team from the University of the Basque Country in Spain. Their findings have been published in the Oral Diseases journal [1].

The researchers stated that while the side effects of antipsychotics have been studied extensively, research on their oral impact is limited [1].

Therefore, the researchers were hoping to study the impact further. To do this, the researchers used data from the European pharmacovigilance database EudraVigilance [1].

This database aggregates reports of suspected side effects from medicines. The entries on the database are submitted by health professionals, patients, and pharmaceutical industry professionals [1].

The researchers analyzed 5,633 reports from this database. They were looking for any patterns, consistencies, whilst also comparing antipsychotics to other medicines [1].

The researchers revealed the most common problems [1]. Alteration of salivary flow was one of the biggest issues. For example, this involves excessive salivation or dry mouth [1]. Both are significant issues for oral health.

The researchers noted that the antipsychotics Olanzapine and Quetiapine were linked the most to dry mouth, whilst Clozapine was linked to excessive salivation [1].

Moreover, the researchers found that cavities, tooth loss, inflammation of the salivary glands, and tongue problems, are other common problems associated with antipsychotic use [1].

Again, Olanzapine and Quetiapine were specifically linked to tooth loss. Aripiprazole was linked to swollen tongues the most [1].

Other problems that were frequent included disturbance to tongue movement, gland enlargement, and involuntary movements of the mouth and jaw [1].

Interestingly, first-generation antipsychotics, also called ‘typical’ antipsychotics, were associated with oral issues more than second-generation antipsychotics [1].

The researchers also pointed out that reports of adverse reactions in the mouth are higher with antipsychotics compared to other drugs [1]. Therefore, this underlines the connection between these drugs and oral issues.

Summary

The findings are rather concerning. Clearly, there is a strong connection between antipsychotics and poor oral health.

It is important to note that not everyone taking antipsychotics will experience oral health problems. Furthermore, some people will just have minor issues.

Additionally, it is important to note that many people are unable to function without an antipsychotic. So they certainly have an important role in modern day society. However, their impact on oral health is regrettable.

Lead author Leire Urien discussed the findings. She noted that while “antipsychotic drugs are associated with adverse oral reactions,” this doesn’t “establish a causal relationship” [4].

Continuing, Urien said that instead, “it means that patients treated with antipsychotic drugs have a higher risk of developing oral conditions, and many of these diseases are likely to be associated with the adverse effects these drugs have on oral health” [4].

But while a causal relationship isn’t certain, there is definitely an association. This means that those who are taking an antipsychotic should take extra care of their oral health.

By doing so, it can give them the best chance of having good oral health and lessening any issues caused by the antipsychotics. Therefore, this can result in positive oral and mental health.

Thinking points…

[1] Based on the above, anyone who takes antipsychotics should ensure they adopt extra strong oral hygiene. But whether you take antipsychotics or not, taking care of your teeth and gums is very important! One thing that can contribute to this is having regular dental check-ups. Regular check-ups allow a dentist to track the progress of your teeth, provide regular advice, and step in when issues arise. We recommend that you book an appointment soon!

[2] Aside from antipsychotics, many other commonly dispensed medicines have side effects that can cause oral health problems. These include antidepressants, painkillers, blood pressure medicines, and some antihistamines. Therefore, make sure that if you take any of these medicines, that you are vigilant about potential problems. Make sure you take good care of your oral health while taking these medicines. If you know anyone taking a medicine listed above, you could share this article with them to make them aware of the potential problems!

What Is the Relationship Between Oral Function and Physical Health Diseases?
21Jul
Recent research has looked into the connection between oral health and physical health. Specifically, they have looked at how oral function impacts three particular areas of overall health. The findings demonstrate the importance of looking after our oral health, given its close relationship with overall physical health.

There is a strong connection between our oral health and our overall physical health. In fact, this connection is much stronger than many people realize.

With awareness of this link growing, there is newfound interest in the factors involved in this connection – especially in terms of how lifestyle-related diseases relate to oral health.

Now, new research has explored this connection [1]. The findings reaffirm the importance of oral health and the close relationship between oral and physical health.

Background

There has been plenty of past research that has demonstrated the link between physical and oral health [2].

For example, it is already known that poor oral health and gum disease have been associated with conditions like Diabetes, Cardiovascular Disease, and Alzheimer’s Disease.

Additionally, poor oral health can also impact a person’s diet and nutritional intake. Consequently, this often impacts lifestyle-related diseases like diabetes or heart disease.

This research was specifically interested in oral functioning and its association with three specific areas of overall health.

The Research

The research was carried out by a team of researchers from Fujita University in Japan. Their study has been published in the Journal of Oral Rehabilitation [1].

The researchers wanted to investigate the link between oral health and the blood test results for three signs of overall health – glucose metabolism, lipid levels, and kidney function [1].

Glucose metabolism refers to the glucose levels a person has in their blood. Abnormally high or low levels of glucose in the blood is usually associated with health complications.

Moreover, lipid levels are closely related to cholesterol. High lipid levels are associated with cardiovascular health problems.

Finally, kidney function is another important area to analyze. The kidneys help to regulate blood pressure and maintain bone health, among other uses. Therefore, having strong kidney function is important.

The research involved 118 participants, all of whom were aged 50 or above. These 118 participants all had a dental check-up in 2021, and an annual physical examination in 2021 and 2023 [1].

The participants were given seven different oral function tests. These were tongue coating measurements, oral dryness, the number of functional teeth, tongue pressure, masticatory function, swallowing ability, and oral diadochokinesis (OD) [1].

Then, the participants were divided into two groups, based on their blood test results. Reference ranges were used in determining the two groups.

One group consisted of those considered to be in a healthy range in their results, and one group featured those considered to be in an unhealthy range [1].

The Results

The results were interesting. The group with unhealthy blood glucose levels had a significantly lower number of remaining teeth and OD (the speed and accuracy that a person can repeat certain syllables) compared to those in the healthy group [1].

Similarly, those with unhealthy lipid levels had high levels of tongue coating (representing high levels of unhealthy bacteria), and low levels of OD compared to those in the healthy group [1].

With kidney function, the results also followed the same pattern. Tongue coating, number of teeth remaining, and OD were all highlighted as problems for those in the unhealthy group when compared to the healthy group [1].

These results clearly show that poor oral health is closely related to poor physical health. The strength of this connection is noticeably very strong.

The difference between the healthy and unhealthy groups were significant. This underlines the scale of the impact of oral function.

Based on these findings, the authors have recommended that oral function tests are used during health check-ups [1]. Therefore, this would allow greater health insights to be gained.

Professor Mitsuyoshi Yoshida commented on the findings. Yoshida said that “our results suggest that a decline in oral function can be a risk factor for lifestyle-related diseases” [3].

Continuing, Yoshida says that “maintaining good oral health is the first step in maintaining overall health,” before confirming the authors have a vision for widescale introductions of oral function tests in health check-ups [3].

Overall, these findings again demonstrate the close link between physical and oral health. The results should serve as a reminder to us of the importance of looking after both our physical and oral health.

Thinking points…

[1] This research underlines the importance of looking after our oral health! Regularly keeping track of the health of your mouth is crucial. Therefore, remember to attend dental clinics regularly for a check-up, as any issues can be spotted and rectified early on. You should attend a check-up at least once every six months. We recommend that you book an appointment soon!

[2] If you are due to have a blood test soon, it could be worth requesting an oral function test too. Clearly, an oral function test provides interesting insights and should provide you with more detailed information on your overall health. If you do have a blood test scheduled, why not have a discussion with your doctor or nurse about having an oral function test too?

Calgary Reintroduces Fluoride to the Public Water Supply: What Has the Reaction Been?
7Jul
The city of Calgary in Canada has formally announced the reintroduction of fluoride into the public water supply. This reintroduction is the latest chapter in Calgary’s long and complex relationship with water fluoridation. At a time when fluoride is being debated intensely, it will be interesting to see how Calgarians, politicians, and scientists react.

The history of the city of Calgary and Water fluoridation is complex, full of twists and turns, and at times, controversy.

Now, the latest milestone moment has taken place, with fluoride having been officially reintroduced to the public water supply [1].

At a time when water fluoridation is a topic of intense debate, the United States and other Canadian cities will be watching to see what impact it has.

What is Water Fluoridation?

Fluoride is a natural mineral that is found in air, soil, and many foods. It also occurs naturally in water. Fluoride is a key ingredient in toothpaste and other oral health products.

Water fluoridation refers to when fluoride is added (in small quantities) to the public water supply. This is done with the intention of improving the oral health of citizens in the area.

The practice is supported by dentists and scientists and is seen as an effective way of improving the oral health of the general population.

History of Calgary and water fluoridation

As mentioned, Calgary has quite the history with water fluoridation. Back in the 1950s, various countries were adopting the practice of water fluoridation.

But in 1957, 1961, 1966, and 1971, Calgarians voted against fluoridation in four plebiscites [2]. For almost two decades, the topic was rather quiet.

But in 1989, a fifth plebiscite resulted in Calgarians voting in favour of fluoridation. Therefore, in 1991, fluoride was officially added to Calgary’s water [2].

Between 1998 and 1999, the level of fluoride was lessened, but support remained, with a 1999 plebiscite resulting in fluoridation remaining [2].

Then, in 2011 the city of Calgary discontinued water fluoridation [2]. Around this time, support was still largely in favour of fluoridation.

The most recent update came in 2021, when Calgarians voted for fluoridation to be reintroduced, with 62% of voters supporting this measure [2].

Now, four years later, fluoride has been formally reintroduced into the public water supply across Calgary. The City of Calgary’s Water Services department confirmed that “Fluoride will be reintroduced into Calgary’s drinking water” in an official statement [1].

Wider debate on water fluoridation

This announcement comes at a time when the topic of water fluoridation is receiving significant public and political attention.

This has been in part due to the actions and comments of United States Health Secretary Robert F. Kennedy Jr. Kennedy, who has been a long-standing critic of fluoride, calling it “industrial waste” [3].

Both Utah and Florida have banned water fluoridation statewide [4]. It looks like other states may follow soon.

One of the key concerns about fluoride is its apparent links to lowering the IQ levels of children. A recent research paper found a link between exposure to high levels of fluoride and lower IQs in children [5].

But supporters of water fluoridation – including dentists – have pointed out that the levels of fluoride seen in the study were higher than the level of fluoride in the water supply.

Other concerns include fluorosis – where too much fluoride is consumed, the potential for a negative impact on thyroid function, risks of behavioral issues in children, and a lack of informed consent.

Calgary and Edmonton study

Water fluoridation has many proponents. Many of these advocates point to a well-known study that shows the positive impact water fluoridation can have on children.

This study compared the oral health of children in the Canadian cities of Calgary and Edmonton [6]. These were used for comparison as Calgary stopped water fluoridation in 2011, whilst Edmonton has continued the practice.

Interestingly, the study found that since 2011, tooth decay in Calgary has increased significantly when compared to Edmonton [6]. Meanwhile, Edmonton’s has stayed largely the same.

Therefore, the researchers were able to conclude that the cessation of water fluoridation in Calgary was associated with a negative impact on the oral health of children.

The above study has been cited by many scientists to underline the positive impact water fluoridation has, along with the damage caused by a lack of fluoridation.

Summary

It will be interesting to see how Calgarians react to the implementation of water fluoridation. This is especially due to the ongoing debate over fluoride.

It is likely that conclusions on its effectiveness will not be made for several years. It will take time to see how Calgary and its citizens respond.

Meanwhile, further research into fluoride will continue. It is likely to be a topic that will remain in the news for many years to come.

But as seen in the Calgary and Edmonton study, there is the potential for a positive impact. Yet weighing up the benefits with the potential drawbacks is where the debate intensifies.

Thinking points…

[1] Remember that if you live in an area with fluoridated water, this isn’t enough to ensure your oral health remains strong! Instead, you need to make sure you adopt excellent oral hygiene, including brushing your teeth at least twice a day and flossing regularly. Moreover, attending regular dental check-ups is very important, as they provide a dentist with the chance to look for any problems and give advice. We recommend that you book an appointment soon!

[2] The topic of water fluoridation is definitely a contested subject area. But remember that whether you live in a fluoridated area or not, water is crucial to drink! Water helps to neutralize acid levels in your mouth and stimulates the flow of saliva. So the next time you reach for a soft drink or juice, try water instead! This can aid your oral health!

How Can a New Eco-Friendly Coating Positively Impact Titanium Dental Implants?
23Jun
Recent research has led to the creation of an eco-friendly coating which appears to positively impact the effectiveness of titanium-based dental implants. The coating appears to improve the biocompatibility and strength of implants. Due to the popularity of dental implants, improving patient experience and treatment outcomes are key goals for dentists.

Dental implants are a popular cosmetic treatment, especially for those who have lost a tooth or teeth. While they typically provide long-lasting results, this is not always the case.

However, new research has yielded the creation of an eco-friendly method which aims to improve the biocompatibility and strength of titanium dental implants, thereby improving their long-term effectiveness [1].

This is a useful finding, especially given the popularity of implants. Moreover, this method is eco-friendly, low cost, and can boost treatment outcomes.

About dental implants

Dental implants are artificial teeth that act and look like a real tooth. They are a great option for anyone that has lost one or more teeth. Common causes of tooth loss include extensive tooth decay, trauma, or advanced gum disease.

The popularity of dental implants has grown in recent years. Past research has suggested that by 2026, almost a quarter of American adults will have at least one dental implant [2].

A common material used in dental implants is titanium. Titanium is used due to its strength, resistance to corrosion, and its ability to co-exist with other teeth.

However, there are limitations with titanium. For example, they are bioinert and do not naturally integrate with bone tissue.

Moreover, recent research has highlighted the potentially negative impact that titanium microparticles can have on the tissues surrounding the implant [3].

Therefore, the researchers wanted to see if they could mitigate these problems. In order to do this, they wanted to create a coating that could enhance the effectiveness of titanium-based dental implants [1].

The Research

The research was carried out by researchers from the SUNY Polytechnic Institute in New York, USA. Their findings have been published in the Scientific Reports journal [1].

The team were hoping to create an eco-friendly way of enhancing titanium-based dental implants, with the aim of improving treatment outcomes [1].

To begin with, the researchers conducted a process called pack cementation. This involved utilizing waste materials like bovine bones to produce a coating that could be applied to the titanium implants [1].

Through pack cementation, the researchers were able to create a hydroxyapatite coating. Hydroxyapatite is the main structural component of tooth enamel which provides hardness [1].

Hydroxyapatite is chemically similar to the human bone, thereby making it an effective and suitable choice to be the coating [1].

Next, the researchers conducted testing to see how the coating would cope in practice. To do so, the team carried out some advanced testing methods [1].

These methods included scanning electron microscopy, X-ray diffraction, and mechanical wear simulations [1]. This enabled the researchers to see how the coating would interact with the implants.

Through the analysis, the coated implants produced excellent results. They demonstrated better strength, improved osseointegration, and improved resistance to friction [1].

Therefore, this produces a range of benefits. By having a better surface strength, the implant would become less likely to fail and have a higher probability of coping with the day-to-day activities of any regular tooth.

Moreover, improved osseointegration is crucial. This refers to the ingrowth of a living bone into the implant. Integrating these areas is crucial, and is a key indicator of the long-term success of implants. Therefore, this improvement is excellent news.

Additionally, having an improved resistance to friction is also positive. This provides further confirmation that the coating can cope with regular tooth-based activities.

Summary

Overall, the researchers were pleased to confirm that they were able to improve the biocompatibility and strength of the titanium dental implants [1].

The hydroxyapatite coating achieved this, with the analysis producing confirmation that this coating could improve the implants.

These findings are very useful in terms of improving patient comfort and treatment outcomes. This should enable implants to become even more popular and produce longer-term results.

Additionally, with this coating being made using eco-friendly waste materials, it is relatively low-cost to produce, which could help to limit costs for both dentists and patients.

Therefore, there are a range of benefits emanating from this research. It is positive to see that improvements continue to be sought after, with the aim of further increasing the effectiveness of implants.

Thinking points…

[1] The focus should always be on preventing dental problems, rather than needing corrective treatment. Prevention can help us to avoid getting into a situation where implants may be needed. As well as engaging in excellent oral hygiene, it is important to attend regular dental check-ups, as this offers a dentist the chance to take a thorough look at your oral health. They will be able to provide advice and suggest treatment if needed. If you don’t have an appointment booked, we strongly recommend that you book soon!

[2] If you are in a position where you have a missing tooth or teeth, then you should definitely consider dental implants! Implants offer long-lasting and natural-looking results. Here at our Calgary dental clinic Savanna Dental, we offer a free dental implant consultation for our patients! This provides you with the chance to find out more information and ask any questions about the treatment.

How Is Dentistry Becoming Kinder for Patients?
9Jun
Having a fear of the dentist is common, with many people finding the prospect of drills and injections off-putting. However, in good news, dentistry is becoming kinder. Less invasive and shorter treatments are becoming increasingly common, aided by technological advancements. This should hopefully reduce feelings of anxiety towards going to the dentist.

For many people, a trip to the dentist can be an uncomfortable prospect. Feelings of nervousness, anxiety, and trepidation are all common.

However, dentistry is changing in a positive way. In fact, it is becoming much kinder, which should ease feelings of anxiety for patients [1].

Kinder and less invasive dental treatments are becoming the norm. Technological advancements are aiding this, with the hope that attitudes towards going to the dentist will improve.

The process of needing dental treatment

In general, dentists recommend that patients should get a check-up at least once every six months. This allows them to check their oral health and to identify any problems.

Tooth decay is a common issue. It is caused by bacteria in dental plaque which produces acids, which eventually results in a cavity developing.

When a cavity does develop, it normally needs to be filled. This is where the fear sets in, as treatment typically involves needles and drills.

Traditionally, the area around the tooth that will be treated is numbed by an injection of local anesthetic. Then, the dentist will remove the decayed part of the tooth with a dental drill. The cavity is then filled with a material, which is known as a filling.

This process results in many people avoiding the dentist. This is normally due to fear of the injection or the drill. In some cases, it is both.

Dental fear is common, with one study finding that 36% of adults in the UK are moderately “dentally anxious” [2]. Some people go years without going to the dentist due to their fears.

Children can be particularly anxious about going to the dentist. If their fear is not challenged, they may get into the unhealthy habit of avoiding the dentist in their older years.

However, times are changing. Needle-free and drill-free approaches are helping to improve the management of tooth decay and ease fears.

Furthermore, there are three particular techniques which are helping dentistry to become kinder. These are Silver Diamine Fluoride (SDF), Atraumatic Restorative Treatment (ART), and the Hall technique [1].

Silver Diamine Fluoride

SDF offers a very different approach compared to traditional techniques. SDF is a clear liquid that is applied directly into the cavity using a small brush.

This process takes only a few seconds, and crucially, does not require the use of needles or drills. Therefore, this represents a much less invasive approach towards treating tooth decay.

In terms of how it works, SDF has antibacterial properties which are capable of killing the bacteria that causes the decay. Additionally, the fluoride in SDF hardens the remaining tooth structure [1].

While it isn’t overly effective in deep cavities, it is effective for shallow cavities. Past research into SDF has found it stopped decay in approximately 80% of cases [3].

However, there is a disadvantages to SDF. SDF causes the treated area to turn black, which is off-putting for many, especially if it involves a front tooth. Despite this, its non-invasive approach makes it a popular treatment.

Atraumatic Restorative Treatment

ART offers another approach to treating cavities. Originally, this approach was developed for use in areas where access to dental equipment was poor. But it is being increasingly used on a widespread basis.

ART involves removing decayed tooth tissue using hand instruments, meaning that no drills or injections are needed. Then, the cavity is filled with a material called glass ionomer cement [1].

Glass ionomer cement is a special material which sticks to the tooth and slowly releases fluoride over time. This helps to prevent further tooth decay.

There are several positives about this approach. For example, it offers a non-invasive and quiet approach and is typically quicker than traditional drilling.

Furthermore, another positive of this treatment is that it can be performed whilst the patient is sat up, which can be particularly effective in young children or those with special needs.

The Hall technique

The Hall technique is also proving to be a popular option in the management of tooth decay. It only works in children, as it is designed for baby/milk teeth.

The Hall technique works by sealing the decayed part of the baby tooth in, rather than removing it. This may seem counterproductive, though there is a method behind it!

The technique involves using a preformed metal crown which is placed over the decayed baby tooth without the need to engage in any drilling, injection, or removal of any part of the tooth.

A special dental cement holds the crown in place. The idea is that the crown will protect the tooth until it naturally falls out and is replaced by the permanent (adult) tooth.

Again, this is non-invasive and easy for children to cope with. Once the crown is in place, in theory no further work should be needed on the tooth.

Looking to the future

These are three approaches that have the potential to be very effective. Having no drilling or injections can be very appealing.

The aim is for patients to be comfortable in attending the dentist. Patient comfort is important for dentists and should result in patients looking after their oral health more.

These kinder approaches can work for both adults and children. For those that have avoided dental care for years, these new approaches may lead to them returning to receive care.

In the future, it is likely that further non-invasive treatments will be created. Hopefully, dental fear will lessen over the next few years.

Thinking points…

[1] We mentioned earlier about when tooth decay occurs, that cavities will develop, resulting in a filling being required. Fillings are very common, but can be avoided. One important element is early detection, as this can help to save as much of the natural tooth as possible. Remember to attend dental check-ups, as your dentist will be able to have a thorough look at your oral health and suggest treatment if needed. Why not book an appointment now?

[2] Further to the above, there are many ways of protecting your teeth from tooth decay. Adopting excellent oral hygiene – through brushing your teeth at least twice a day and flossing – is crucial. Moreover, avoiding sugary foods and drink can help too! Having a healthy diet rich in nutrients can be very effective. By putting these measures in place, it should maximize the chances of strong oral health!
