The CDC Confirm Outbreak of Dental Infection: What Happened and What To Look Out For?
14Nov
The U.S. Centers for Disease Control and Prevention have issued a warning following confirmation of a recent outbreak of a nontuberculous mycobacteria infection. This appears to have been caused by contaminated water lines in some dental clinics. Now, medical professionals are urging parents to look out for symptoms in their children and themselves. Fortunately, treatment is available for those who have caught the infection.

The U.S. Centers for Disease Control and Prevention (CDC) have issued a warning that some American children have caught a serious infection from contaminated water lines in some dental clinics [1].

The infection, caused by a bacteria type called Nontuberculous Mycobacteria (NTM) is rare. But small clusters of cases in recent years have taken place, with the CDC now becoming aware of another recent cluster [1].

The harmful bacteria lodge in the narrow water lines of dental equipment. This equipment is used for everything – from routine cavity fillings to more complex procedures like root canal treatments.

What is Nontuberculous Mycobacteria?

NTM is a type of bacteria. It is found in water, marshland and soil. However, it shouldn’t be confused with mycobacteria tuberculous – which causes Tuberculosis.

While children are predominantly at risk, adults can also be affected. Infections typically occur after either wisdom teeth extractions or root canal treatments [1].

One of the most notorious past outbreaks of NTM came in California in 2016 [1]. 71 patients were treated for NTM infection [1].

NTM is not the only infection or disease linked to dental water lines. For example, Legionella Disease is another type of bacteria that has contaminated water supplies in dental clinics in the past [3].

The new outbreak

This most recent outbreak was in March 2022, which the CDC was alerted to [2]. An investigation into this new outbreak is being carried out by the CDC [2].

Initial visits to the dental clinic under investigation found that the tested water line resulted in microbial counts far higher than the level recommended by the CDC [2].

Symptoms and treatment of an NTM infection

The symptoms of an NTM infection usually involve swelling in the jaw or neck. Moreover, an abscess, pain, weight loss, night sweats and general fever are other symptoms to look out for [4]. Symptoms do not always appear immediately. Instead, they can slowly appear.

If left alone, hearing loss, permanent tooth loss and facial nerve palsy are potential consequences [1]. This underlines the importance of getting help if you believe you have an NTM infection.

NTM infections usually get worse over time [1]. Treatment usually requires surgical removal of the diseased tissue. This can result in loss of the jawbone, and potentially even teeth [1]. Antibiotics are commonly prescribed as part of a multi-drug regimen [1].

In every case in the past that has involved NTM infection following dental treatment, a surgical procedure has been required to resolve the issue [1]. Therefore, this shows the possible damage of an NTM infection.

The CDC’s comments

Dr. Michele Neuburger is a dental officer within the CDC’s Division of Oral Health. She commented on this development. She says that “NTM infections following dental procedures are very serious” [1].

Neuburger continued by warning that “these infections can be resistant to antibiotic treatment”, before calling them “difficult to treat” [1].

Continuing, Neuburger says that “if dental water lines are not maintained properly and regularly treated with germicides, these bacteria, along with other microorganisms in the water, will attach to the interior surfaces of the water-line tubing and form a biofilm, which serves as a reservoir where microorganisms can grow and increase in numbers” [1].

Neuburger continued to explain by saying that “pieces of biofilm can break off into the water system and then be released into the patient’s mouth” [1].

Furthermore, Neuburger has urged parents to contact their dentist immediately if they suspect themselves or a child of theirs has developed an NTM infection [1].

The CDC have made some recommendations to dental clinics. These include the regular use of chemical germicides in the water lines – which can help in lessening the threat of bacteria.

It is important for dental clincis to follow these guidelines. Moreover, this involves maintaining equipment and following safety procedures for water to ensure that it is safe for use.

These infections are rare, but do happen. Remaining vigilant both before and after dental treatment is important. Our oral health is crucial, and should always be a priority for us all.

Thinking points…

1) While this is concerning, do not let this put you off attending the dentist. Please remember that NTM infections are very rare. Visiting the dentist is very important for both yourself and your children. Regular check-ups can help to ensure your oral health is strong, and identify any potential problems. Remember to book an appointment when needed!

How Have the Conservatives Reacted to Canada’s New Dental Care Plan?
9Oct
The Conservatives have questioned many aspects of the National Dental Care Plan that the Liberals and New Democratic Party have put forward. They are concerned that the plan – which is aimed at helping low and middle-income families to receive dental care – will increase inflation and worsen Canada’s economic situation. They have suggested the dental care plan should be quashed, though due to the support for the plan, it is likely that it will go ahead as scheduled.

The Conservative Party have questioned certain elements of the National Dental Care plan, which is gathering momentum ahead of its initial rollout in the next few months.

The Conservatives have voiced their opinion that the dental plan – which is aimed at helping low and middle-income families to receive dental care – will increase inflation at a time when a cost of living crisis is developing [1].

They have argued that the plan should be quashed. However, with the Liberals and New Democratic Party (NDP) in support of the plan, it is unlikely that it will be annulled

The current situation of the dental plan:

In March 2022, the Liberal Party, in conjunction with the NDP, announced the creation of a new national dental care plan [2]. This was part of the supply and confidence agreement between the NDP and the Liberals.

The Liberal Party have committed to spending $5.3billion over the next few years on the plan. The full rollout is due by 2025. The plan is aimed at those with a household income of below $90,000 [2].

However, the nature of the dental plan and its lack of direction or strategy has led to it being shrouded in controversy. In fact, the NDP have threatened to end their supply and confidence agreement with the Liberals unless the dental plan goes ahead.

Finally, an update came a few weeks ago. The Liberal Party announced that children from low and middle-income families under the age of 12 will be the first to benefit. All of the facts weren’t made clear, but it was a step in the right direction.

Moreover, the most recent update revealed that for every child under the age of 12, low and middle-income families would receive $650 per year towards dental care [2].

The Conservative Party’s Reaction

However, the dental plan hasn’t proven to be universally popular. The Conservative Party has led the disapproval of the plan [1]. They are not the only ones either.

One of the main concerns is the timing of this plan. Given that energy prices are soaring, the cost of living is increasing and gas is expensive, there have been some suggestions that this isn’t the right time to be launching this plan [1].

The Conservatives have argued that the dental plan is going to make Canada’s already fragile economy worse by increasing inflation [1]. They believe government spending should be lowered at this time, rather than having a large initiative being launched.

Conservative MP Michael Cooper has been among the most vocal in his opposition to the dental plan. Cooper argued that “the bill offers measures throwing some money here, throwing some money here, all in a desperate effort by a desperate government to make it appear that it is doing something – anything – to address the cost-of-living crisis” [1].

Moreover, MPs from the Bloc Quebecois Party have also raised concerns [1]. They have argued that there is a lack of clarity on whose jurisdiction dental care should fall under [1]. For example, in Quebec, the health system already covers the dental needs of children under the age of 10 – leading to questions on how this plan might be implemented there [3].

Bloc MP Marie-Helene Gaudreau spoke on behalf of her party by saying that the party may “vote against a bill” [1]. However, this is not because they don’t agree with it, rather “out of a concern about respecting jurisdictions”, Gaudreau said [1].

The Conservatives are pushing for an amendment that would result in the bill being quashed. However, with the Liberals and NDP holding a majority, their amendment is unlikely to gain the support needed for it to be annulled

What this means

The dental plan has certainly been a source of discussion for some time. However, the fact that some concrete plans have been put forward shows that it is on the right path.

But opposition remains. It is certainly a difficult time for Canadians due to the cost-of-living crisis. This has led to some believing inflation will worsen, causing further problems. However, many will see the dental plan as a way of saving money whilst improving the oral health of their children.

While the dental plan is going to be expensive to rollout, it should result in long-term benefits to the oral health of Canadian citizens. Moreover, it should put less strain on the healthcare system in the long-run. As each week passes, we get closer to the unveiling of the plan

Thinking points…

1) Many people reacted to the announcement of a national dental plan with excitement. But while it may be tempting to think this means it isn’t as important to look after your oral health as before, this is incorrect! It is still very important to have excellent oral hygiene, as this can help to prevent treatment to be needed. One of the most important aspects of this is to attend regular dental check-ups – as a dentist will be able to provide you with an overview of your oral health. We recommend that you make an appointment soon!

2) What are your thoughts on the dental plan – do you think it is a positive or a negative idea? Why not discuss this with a friend or family member? Feel free to share this article with them to see what they think. It may offer you an idea of what others are thinking, which is interesting given what a complex topic it has become.

Could a New Gel Result in More Effective Treatment for Gum Disease?
26Sep
A new topical gel has been created by a research team, which appears to be capable of treating gum disease in a more effective way than current treatments. The gel is capable of blocking the receptor for something called Succinate – which is known to be associated with Gum Disease. This can suppress inflammation in the mouth. Such findings are exciting, and could in the future result in better treatment outcomes for gum disease.

Recent research has led to the creation of a new topical gel which looks like it can treat Gum Disease in an effective way. The gel can suppress inflammation in the mouth by targeting the receptor of a molecule called Succinate [1].

Given how many people suffer from gum disease, this is an exciting finding. Gum disease can be challenging to treat.

In the long-term, the aim is that the gel could be used at home by a person in an effort to prevent or treat gum disease [1].

Background

Gum disease is one of the most common oral health conditions, and affects a huge number of people around the world. Symptoms include inflammation, redness around the gums and pain.

Gum disease typically involves an imbalance of unhealthy and healthy bacteria within the mouth. In the worst cases, gum disease can result in bone destruction, chewing issues and loss of teeth.

Studies suggest that gum disease affects up to half of adults aged 30 and above [2]. This shows the sheer scale of the impact of gum disease. Therefore, finding an effective treatment would have a very positive impact.

The Succinate Connection

This research considered the impact of Succinate. Succinate is a molecule that is produced during metabolism. Past research has showed that those with high levels of succinate typically have higher levels of inflammation [3].

Moreover, high levels of succinate is also associated with speeding up the process of bone loss, which is something that is a consequence of advanced gum disease [3]. Succinate is naturally produced by the human body.

The Research

The research was done by New York University’s (NYU) College of Dentistry. Their findings were then published in the journal Cell Reports [1].

To begin with, the researchers wanted to confirm the link between succinate and gum disease. They examined dental plaque samples from humans and mice [1].

Then, the researchers used metabolomic analysis to determine the levels of succinate in those with gum disease, and those without [1]. As they had expected, those with gum disease had higher levels of succinate than those without [1].

While doing this analysis, the researchers noticed that the succinate receptor was active in the gums of both humans and mice. Therefore, the researchers hoped to look further into this. To do this, they genetically altered some mice in a way that their succinate receptor would be inactivated [1].

In the mice with an inactivated receptor, the researchers measured the levels of inflammation in the gum tissue and blood of mice with and without gum disease. As a result, they found that mice with an inactivated receptor had lower levels of inflammation in their gum tissue and blood [1].

The investigation into the succinate receptor uncovered other findings too. Mice with gum disease had a greater imbalance of bacteria than the mice with inactivated receptors did [1]. Moreover, they also showed less bone loss – which further cemented their conclusions over succinate [1].

To ensure their findings were accurate, the researchers administered extra levels of succinate to both sets of mice [1]. For the mice with regular receptors, their gum disease worsened. However, for the mice with an inactivated succinate receptor, their mouths were mainly protected against inflammation, increases in unhealthy bacteria and bone loss [1].

This clearly showed that when the succinate receptors were inactivated, that better oral health followed. Therefore, elevated levels of succinate and the activation of the succinate receptor are key factors in gum disease [1].

Based on this knowledge, the researchers developed a gel formulation that is aimed towards treating gum disease [1]. The gel is a small compound that is capable of targeting the succinate receptor – with the aim of stopping it from activating [1].

Subsequently, lab studies were carried out on human gum cells, which found that application of the gel resulted in reduced inflammation and other processes that are associated with gum disease [1].

Then, the gel was applied to the gums of mice with gum disease. A group of mice with gum disease were not given the gel. Over a 4 week period, it was found that inflammation was significantly reduced, while bone loss was cut in half in the mice that received the gel compared to those that didn’t [1].

Therefore, the findings clearly showed that this gel was able to successfully lower inflammation and bone loss – two key consequences of gum disease [1].

Implications for the future

The authors were delighted with the results. Author and Associate Research Scientist at NYU’s College of Dentistry. Yuqi Guo, commented on the findings. He said that “no current treatment for gum disease simultaneously reduces inflammation, limits disruption to the oral microbiome, and prevents bone loss. There is an urgent public health need for more targeted and effective treatments for this common disease” [4].

Now that the results are clear, the researchers are hoping to use the gel on other animal models, which will enable the researchers to have an idea on the appropriate dosage and timing for application of the gel [4]. Toxicity will also need to be checked [4].

The long-term goal of the team is to develop a gel and oral strip that regular people can use at home in an effort to treat gum disease [4]. Moreover, they are also aiming to develop a slow-release formulation that dentists could use to fill pockets in the gums of those with gum disease [4].

Given how many people suffer from gum disease, if this treatment did eventually get used, it would be highly popular. It could result in the oral health of many people around the world being improved.

Thinking points…

1) This article mentions gum disease, which is a condition that affects so many of us. It is important to look after our gums – they are a critical part of oral health. Therefore, if you think you may need attention to your gums, why not discuss your options with your dentist? Treatment options typically include root planing, scaling or a gum graft. We recommend seeing a dentist soon!

2) Preventing gum disease is possible. Like all other oral health conditions, strong oral hygiene can help in many cases. This includes brushing and flossing regularly, eating healthily, and attending dental appointments on a regular basis. At these appointments, a dentist will be able to take a look at your gums and your overall oral health, and judge whether or not treatment is needed. Consider booking an appointment right away!

What we offer at Savanna Dental

Savanna Dental is a Calgary dental clinic that offers many services, including regular check-ups, cavity fillings and root canals.

We are also pleased to offer some cosmetic services. Here at our Calgary dental clinic, we offer treatments like tooth whitening, Invisalign™ and dental implants.

Liberals Announce First Steps for Canadian Dental Care Plan: What Is Involved?
19Sep
The first steps of the upcoming Canadian Dental Care plan have been released. The plan will be rolling out shortly, with children of low and middle-income families under the age of 12 due to be the first to benefit. The proposed Canadian Dental Benefit should help improve access to dental healthcare for millions.

The Liberal Party has announced new measures aimed at helping Canadians to cope with the cost-of-living crisis. Among these measures is the long-awaited first steps of the National Dental Care plan [1].

The dental care plan has been a common talking point in recent months, with Justin Trudeau’s Liberal Party under pressure from the New Democratic Party (NDP) over the dental plan. This is part of their confidence and supply agreement.

Finally, progress has been made with the dental care plan, with some steps outlined ahead of its rollout, which is due to be by the end of the year.

The Dental Care Plan

Back in Match 2022, the Liberal Party announced an agreement with the NDP involving the creation of a new national dental care plan [2].

The plan is aimed at low and middle-income families in Canada – specifically those who earn under $90,000 per year.

The Liberal Party have committed to spending $5.3billion over the next five years to launch the plan [2].

Updates

The Liberals are aiming to roll out the first stage of their dental care plan shortly. The announcement has a target implementation date of December 1st 2022.

The first part of this plan will benefit children aged under 12 who do not have dental insurance [1].

Such children, whose family income is lower than $90,000 per year, can access up to $650 per year for the next 2 years for dental services [1].

The following payments will be available:

• $650 would be provided for each eligible child if the family’s adjusted net income is under $70,000.

• $390 would be provided for each eligible child if the family’s adjusted net income is between $70,000 and $79,999.

• $260 would be provided for each eligible child if the family’s adjusted net income is between $80,000 and $89,999 [3].

In order to access the Canadian Dental Benefit, parents or guardians of eligible children will need to apply through the Canadian Revenue Agency.

Trudeau has announced that by the end of 2023, the dental care plan will be extended to under 18’s, seniors, and those with disabilities [1]. This will form the next step of the plan.

Then, the aim is that by 2025, full implementation of the program will have taken place. Hopefully by then, the dental plan will be helping Canadians all over the nation.

Reactions

There is a growing consensus among many Canadians that an intervention is needed into dental costs. For example, a 2018 study found that 22.4% of Canadian adults avoided going to the dentist because of cost [4].

Moreover, over a third of Canadians do not have dental insurance [4]. Therefore, it can be very difficult for this group and their dependents to receive dental care. Avoiding dental treatment can result in intense pain, possible tooth extractions and physical health complications.

As a result, this dental plan is expected to help a large amount of people. It has been one of the NDP’s main goals as a political entity.

As mentioned, Trudeau’s Liberal Party have been under pressure from the NDP. NDP leader Jagmeet Singh was delighted with the update, stating that “we have won” [1].

Singh commented that the dental care plan would not have happened, “but for the fact that we forced the government to deliver on this respect for people” [1].

But Singh is not resting on his laurels, and is saying that his party will continue to put pressure on the Liberals. The NDP’s expectation is that the government will continue to rollout the dental plan successfully over the next few years.

Aside from his announcement on the dental care plan, Trudeau also spoke about boosting the GST tax credit, whilst providing a one-time increase to the Canada Housing Benefit [1].

Thinking points…

1) While news of this dental plan is certainly exciting, it is important for us all to remember that it won’t be implemented overnight. What we mean by this is that you shouldn’t wait for the dental plan to begin before seeking dental treatment. Ensure you practice excellent oral hygiene. If you do need any assistance, remember to see your dentist soon for a check-up. In fact, why not book an appointment now?

2) As discussed above, cost is clearly an issue for many when it comes to accessing dental care. However, at our Calgary Dental Clinic Savanna Dental, our fees are set in line with the Alberta Dental Fee Guide, which means we offer transparent and competitive costs to our patients. For more information about us, we recommend visiting our website https://savannadentalclinic.ca! We offer many different services, and would love to speak soon!

Why Does “Positive Stress” Actually Boost Tooth Tissue Regeneration?
12Sep
Recent research has found that “positive stress” can make good changes in tooth stem cells – which can make them more resistant to injury and disease. This boosts the potential of tooth regeneration too, and could help with more extensive research into tooth regeneration in the future. These findings come after a range of areas to do with cells and teeth were examined.

Stress is often seen as something negative. However, recent research has found that “positive stress” is capable of making good changes in tooth stem cells – which can make them more resistant to injury and disease [1].

In the past, when there have been issues with our natural teeth, it is common to turn to dentures or implants. But such research suggests that regenerating our natural teeth could be a possibility.

What happens when teeth get damaged?

The main research looks at the steps taken when teeth become damaged. When a tooth gets damaged, either through injury, trauma or decay, the tissue inside the tooth can become exposed to harmful bacteria. Moreover, it becomes vulnerable to infection.

If the tissue inside the tooth becomes fully infected, there are only a few current treatments. This includes a root canal treatment or extraction. At third option can be to remove the pulp in the tooth and fill the canal with artificial materials like rubber or cement.

This third option does however pose problems – as these artificial materials dry over time. Unfortunately, this means that extraction becomes likely – which is something all dentists try to avoid.

Therefore, scientists have looked for a long time at finding ways where a teeth is able to regenerate itself, and not need any manual work from dentists to do so.

The Research

The research was completed by a team from the Hong Kong University of Dentistry. Their work has been published in the Journal of Dental Research [1].

The authors acknowledged that the usual approach towards dental pulp regeneration – which involves stem cell-based therapeutics – has its limitations [1]. This is because a tooth’s root canal is surrounded by tissue with a limited blood supply, making it a harsh environment for any cells to be viable in. Moreover, with the low oxygen levels making it almost impossible for any cell transplant to thrive in.

The team instead used a technique where they modified the cells genetically, yet altered them to include a responsive state for low oxygen conditions – causing “stress” [1]. Therefore, this could theoretically help the cells to survive in the environment described above.

The research involved the root canal of a human tooth fragment being implanted into mice. The root canal was altered using the technique above. The researchers observed the mice, after 28 days they witnessed that tissue formation had occurred [1].

This research was able to show that such a technique appears to work. By adapting some elements in tooth stem cells, the stress was able to boost the regeneration of the tooth [1].

The researchers concluded that this positive stress could result in tooth stem cells becoming more resistant to disease and injury [1]. This would clearly have an excellent impact on teeth.

What this means

Overall, this research has been able to show that positive stress can have a positive impact on tooth stem cells, and can help to improve survival of teeth, and also play a potential role in tissue regeneration.

Dr. Dissanayaka is Assistant Professor in Oral Biosciences at Hong Kong University of Dentistry. He commented “former research has revealed that our cells possess (a) number of adaptive mechanisms for stress” [2].

But by pre-conditioning the cells genetically, this “significantly enhanced the dental hard tissue formation within the regenerated pulp tissue” – Dissanayaka says [2]. Continuing, he says that “tooth stem cells have an inherent capacity to survive under stress” [2].

Looking ahead, the authors aim to identify drugs that could be used in clinical tissue regeneration. This, along with the research carried out above, will help the team to form new strategies to improve the potential of tooth stem cells.

Thinking points…

1) The idea of tooth regeneration is certainly exciting. However, as always, the focus should be on prevention rather than treatment. The best way of preventing dental issues is to have strong oral hygiene, including brushing your teeth regularly, flossing, and eating healthily. Another hugely important aspect of strong oral health is to have regular dental check-ups. We should have a check-up at least twice a year, why not book an appointment now?

2) It is important to remember that unlike many parts of the body, a tooth won’t automatically recover if it becomes damaged. Despite the regenerative topics outlined above, it isn’t something we will see overnight. It can be tempting to avoid visiting the dentist if you are in pain, as you may think it isn’t necessary. But if you leave problems untreated, they will only get worse. Therefore, if you do need treatment, do ensure that you book in an appointment!

Is Water Fluoridation an Environmentally Friendly Approach to Preventing Tooth Decay?
5Sep
Following a thorough study, researchers have found that water fluoridation is the most environmentally friendly approach to preventive dental care. There are a range of measures that are recommended to combat tooth decay, with water fluoridation commonly used. In an age where all industries are aiming to improve their environmental footprint, these results affirm the usefulness of water fluoridation.

Across all industries, there is a big focus on sustainability and the environmental impact that industry output has. Healthcare is no exception. In dentistry, efforts are being made to improve the environmental footprint.

Therefore, researchers have been searching for ways to improve processes in dentistry, in order to aid the effort against the climate change crisis.

As part of this overall goal, a recent study looked at various preventive measures against tooth decay in dentistry, with the aim of finding which method was the most environmentally friendly. The research produced interesting results.

Background

Tooth decay affects a huge number of people. Tooth decay impacts the healthcare industry due to a very high demand for treatment. But fortunately, there are many preventive measures – including fluoride toothpaste and a fluoride varnish.

However, water fluoridation is another preventive measure that is used in some countries. In fact, water fluoridation is widely regarded as one of the most effective healthcare interventions of the 20th Century [1].

Water fluoridation involves a small concentration of fluoride being added to the public water supply. Fluoride is a crucial ingredient for teeth, and helps to strengthen them. Studies have consistently linked water fluoridation to strong reductions in cavities [2].

Approximately 35% of the world’s population has access to fluoridated water [3]. But it has proven to be a controversial subject. Many countries have outright banned its use, while many others are unable to provide easy access to fluoridated water.

The Research

The research was a collaboration between Trinity College Dublin, Ireland, and the University College London, United Kingdom [4]. Subsequently, their work was published in the British Dental Journal [4].

The researchers looked to quantify the environmental impact that water fluoridation of the public water supply has for a 5-year-old child over a one-year period [4]. In the United Kingdom – where the study took place – water fluoridation is rather common.

They intended to compare this to the environmental impact of more traditional approaches like fluoride varnishes and regular toothbrushing programs [4]. This would allow them to see which preventive approach is the best environmentally.

In order to quantify the impact of the three approaches, the research team conducted a “Life Cycle Assessment” [4]. To do so, the researchers carefully measured the combined travel, weight and amounts of all products and processes involved in the three preventive programs mentioned above [4].

Then, the researchers inputted their data into a specialized computer program called OpenLCA [4]. Therefore, this provided the researchers with information, figures and statistics pertaining to environmental outputs of each of the preventive measures.

The results showed that water fluoridation had the lowest environmental impact of all three measures [4]. This was the key finding of the research, and shows that water fluoridation has a strong environmental impact when compared to other methods.

Moreover, the researchers also found that water fluoridation had the best return of investment, which is important for councils and governments to weigh up when deciding on legislation relating to water fluoridation [4]. Therefore, such results are useful.

The researchers concluded that after balancing out clinical effectiveness, environmental sustainability and cost implications – that water fluoridation should be the preventive measure of choice [4].

What this means

This research has showed the potential impact that water fluoridation can have. Not only is it highly effective, but it also has a strong environmental impact as well.

With the world in the midst of a so-called “climate crisis”, such findings could be very important. Water fluoridation seems to present a cost-effective and efficient way for governments to lower their environmental footprint, whilst lessening tooth decay.

But sadly, water fluoridation continues to be a controversial topic. This has resulted in many nations avoiding its use. Yet research results like the above could result in a change of opinion.

This research though does show the benefits of water fluoridation. At the very least, for those who do have access to fluoridated water, they have added protection against tooth decay.

Thinking points…

1) This study is a useful reminder of the benefits that fluoride can bring. Not everyone is in an area where the public water supply is fluoridated. If you don’t have access, remember that it is important to always use a fluoride toothpaste. It is also important to attend regular dental check-ups, as this will provide your dentist with a chance to examine your mouth, and suggest treatment if necessary. Why not book an appointment now?

2) If you do have access to fluoridated water, it is important to not get complacent. Just because you have fluoridated water, this doesn’t replace the need for strong oral hygiene, regular cleaning and flossing, and attending dental appointments. If you haven’t seen your dentist for a while, it is especially important to book a check-up, as any problems can be detected. Importantly, continue to practice excellent oral hygiene!
