New research has sought to find out if early childhood exposure to the chemical fluoride has an impact on the cognitive neurodevelopment of children. The topic of fluoride has been in the news a lot recently, so research into this subject is important. The findings may help to shape public health policy towards fluoride.

One of the most polarizing scientific debates in the modern day revolves around the chemical fluoride – with its impact and whether or not it should be added to the public water supply being heated discussion points.

Research has consistently found that fluoride is good for our oral health. It helps to strengthen our enamel, combat tooth decay, and fight off harmful bacteria [1].

However, there have been concerns raised regarding fluoride’s impact on children, including fears of over-exposure to the chemical and its impact on cognitive development [2].

Now, two senior organizations in oral healthcare have announced the publication of a new study that examines how cognitive development among young children is affected by exposure to fluoride.

Background

As discussed, fluoride is a chemical that has attracted significant debate. The oral health benefits are clear, and it is a key ingredient in both toothpaste and mouthwash.

However, the main controversy surrounding fluoride is its addition to the public water supply in some areas – known as water fluoridation.

In the United States, the debate over water fluoridation has received more attention recently due to the imminent appointment of Robert F. Kennedy as the head of the US Department of Health and Human Services [3].

Kennedy has opposed water fluoridation, and has announced that he plans on advising all US water systems to remove fluoride from the public water supply.

One of the main concerns put forward by opponents of water fluoridation is its impact on children. Moreover, this is especially in relation to exposure in early childhood.

This includes overexposure to fluoride, and concern about its impact on cognitive neurodevelopment. Therefore, new research has been conducted to look into this further.

This important study has been supported by The International Association for Dental, Oral, and Craniofacial Research and the American Association for Dental, Oral, and Craniofacial Research (AADOCR) [4].

The Research

The research was conducted by a team from The University of Queensland’s School of Dentistry. Their findings have been published in the Journal of Dental Research [4].

The team sought to investigate potential effects of fluoride exposure on the cognitive neurodevelopment of children. To find this out, the researchers used the 4th edition of the Weschler Adult Intelligence Scale (WAIS-IV) [4].

The participants in this study were a sample of Australian adults. The sample data was selected from the National Child Oral Health Study (NCOHS) 2012-14 [4].

When adults completed the NCOHS, they were aged between 6 and 16. Data was collected on oral health behaviours, socioeconomic factors, and residential history – the latter of which was crucial for determining which children had access to fluoridated water [4].

Furthermore, the children were examined by trained examiners to assess dental fluorosis – which is a reliable marker of fluoride intake during early childhood [4].

The sample – consisting of 357 participants – were then contacted to provide an update between 2022 and 2023. By this point, the participants were aged between 16 and 26 [4].

This update had the aim of collecting data on cognitive neurodevelopment using the WAIS-IV – which was administered by trained examiners [4].

The researchers then used multivariable regression models to calculate the results and any associations between the various areas [4].

Interestingly, the results showed no statistical difference between those exposed to fluoride and those that were not exposed to fluoride [4].

In fact, the regression analysis even found that IQ scores were slightly higher among those exposed to fluoride [4]. Although this was a very small difference.

Overall, the researchers concluded that early childhood exposure to fluoride does not have an effect on cognitive neurodevelopment, with their analysis demonstrating this [4].

Summary

The researchers were pleased with the findings. They hope that the results of this research will be able to play a part in shaping healthcare policy over the next few months – which coincides with crucial decisions being made in the United States.

Effie Ioannidou is the President of the AADOCR. She commented on the findings, stating that “the fluoridation of drinking water has been enormously beneficial to oral health over the decades, and to public health more generally” [5].

Continuing, Ioannidou said that “it is crucial that a wealth of scientific evidence is always available should the public ever need reminding of this fact” [5]. She says that this research is an example of this.

While there are some risks with fluoride – such as overexposure – managing the balance between the risks and benefits of fluoride is crucial.

But these findings add to the body of research which suggests fluoride has a positive impact on our oral health, and little to no impact on cognitive neurodevelopment.

Thinking points…

1) Some areas have access to fluoridated water, while others don’t. Regardless of whether you live in an area with fluoridated water or not, it is very important to visit your dentist regularly for a check-up. At a check-up, a dentist can take a thorough look at your oral health, and provide advice and suggest treatment if necessary. We recommend that you book an appointment now!

2) With fluoride being in the news so much recently, some people have decided to change to a non-fluoride toothpaste. This has the potential to cause significant dental problems! Therefore, the contents of this article could be very helpful to many people and help to downplay their fears. You could share this article on your social media channels to raise awareness, it could benefit many people. Why not share the article now?!

The Canadian Parliament has approved a $21 billion spending bill, with $317 million of this being allocated to the Canadian Dental Care Plan (CDCP). This represents a positive boost for the CDCP. Many people continue to benefit from the plan, with this additional funding likely to improve the CDCP’s potential further.

The Canadian Parliament has agreed to allocate an additional $317 million to the Canadian Dental Care Plan (CDCP), in a positive boost to the oral health of Canadians [1].

The CDCP has the aim of improving oral health for Canadians and assisting those with a low income in affording dental care. This additional funding should help to further the potential of the CDCP.

The $317 million addition in funding for the CDCP comes as part of a wider $21 billion spending bill which has been approved by parliament.

What is the CDCP?

The CDCP launched in December 2023. Since then, over one million Canadians have accessed services offered by the plan [2]. Therefore, it has had a significant impact already.

Dental costs are high in Canada, with research showing that approximately 25% of Canadians avoided seeing a dentist in 2022 due to cost concerns [3].

Many Canadians have developed poor oral health, and have not been able to access the treatment they have badly needed. Therefore, financial support for those with a low or medium income is important.

The CDCP assists those with an annual family income of less than $90,000. Prior to the update in parliament, $13 billion had been put aside for the CDCP, though this has now changed [1].

Parliament approves extra funding

Parliament was voting on a $21 billion spending bill, which the ruling Liberal Party had requested last month. The aim is for the $21 billion to fund various programs [1].

For example, one such program was the CDCP. The Liberals wanted a further $317 million to be allocated to the CDCP as part of the spending [1].

MP’s representing the Liberals, New Democratic Party (NDP) and Bloc Quebecois were among those to vote in favour of the additional funding [1]. NDP leader Jagmeet Singh has been a vocal supporter of the CDCP.

The Conservative Party opposed the entire spending bill – including the injection of further funding into the CDCP [1]. But there were enough votes in favour to pass the bill.

Overall, this additional $317 million will add to the $13 billion that has already been committed to the CDCP for the next five years [1]. Therefore, this should help with extending the reach of the plan further.

Anita Anand – President of the Treasury Board – has said that she was pleased that “the majority of members in the House of Commons recognize that the supports” are the “supports that Canadians need” [1].

What will happen next with the CDCP?

As discussed earlier, the CDCP has been rolled out on a gradual basis. This means that not everyone is currently available to apply for the services under the CDCP.

For example, the elderly, children, and those with disabilities are among those who are eligible to apply for the plan (provided they meet eligibility requirements).

However, in 2025, the aim is for the CDCP to open up to everyone. It isn’t yet known when in 2025 this will be, but the federal government remains confident of this happening at some point next year [4].

Health Minister Mark Holland has admitted that “I know people are anxious” regarding when they will become eligible for the CDCP [4].

Furthermore, Holland has said the government are working in order to make the plan available “as soon as possible in the new year” to apply for [4].

It is believed that around 9 million Canadians meet eligibility requirements. However, only 3 million of this group are currently eligible. Therefore, there is still a sizeable number of people – mainly those aged 18-64 – who are still waiting to be able to apply [4].

It isn’t known yet whether the additional $317 million will be spent on extending some of the services offered through the CDCP. Currently, services offered include cleanings, fillings and dentures.

Seeing the extra funding being agreed is positive, and underlines the government’s commitment to improving the oral health of Canadians. Hopefully, this funding will further improve the CDCP, and lead to more people benefiting from the plan.

Thinking points…

1) While the federal government are hoping for the CDCP to open to those aged 18-64 during 2025, it isn’t likely to be in the early part of the year. Unfortunately, some people are ignoring pressing dental issues in an effort to wait to become eligible for the CDCP. However, it is important to not wait for the plan, as problems will only become more severe. Therefore, make sure you carry on attending regular check-ups, as these allow a dentist to review your oral health. We recommend booking an appointment now!

2) Earlier we mentioned about how the price of dental care in Canada means that many people are unable to afford care. However, here at our Calgary-based dental clinic Savanna Dental, our prices are set in line with the Alberta Dental Fee Guide, which ensures transparent and competitive prices.

A key goal for researchers is that one day, humans will be able to regrow lost teeth. Scientists have been exploring this possibility for several years, but have struggled to make progress. Now, a new facility has opened in Canada which aims to take inspiration from fish in terms of finding ways of regrowing teeth.

When you think about the possibility of regrowing teeth, it is unlikely that your first thought might be based around fish. However, you might do soon!

Some tropical fish have the ability to grow and then shed multiple sets of teeth over their lifetime. Unfortunately, humans only get deciduous teeth, and then adult teeth.

With this unique ability in mind, a new research facility which will study fish closer has been officially opened [1]. The aim is that one day, human teeth will be able to regrow.

University of Manitoba’s New Facility

The University of Manitoba in Canada has officially opened a new facility called the Rady Biomedical Fish Facility, which is part of the Rady Faculty of Health Sciences [1].

This facility, which cost $2.5 million, has the aim of advancing research into the possibility of the regrowth of teeth – something which has been a key research subject for decades [1].

The facility is equipped with modern tools which can be used to study two freshwater species – zebrafish and Mexican tetra fish. Currently, there are approximately 2,000 zebrafish and 250 Mexican tetras at the facility [1].

The use of fish

Fish are very useful species to study. As Dr. Benjamin Lindsey – who works at the Max Rady College of Medicine – says, “about 70% of fish genes are the same as human genes” [1].

Therefore, scientists can learn a lot through studying fish. When using a microscope, researchers can study how the bones, teeth, organs and sensory systems of fish develop [1].

Lindsey has stated that “we’re trying to understand what’s unique, what’s special about the fish that lets them do this” [1].

By gaining a thorough understanding of the genetics behind the regeneration of teeth, the researchers believe that they will – echoing the words of Lindsey – be able to find out what is unique and special about the fish.

The hope is that this will eventually pave the way for dentists of the future to learn how to regrow teeth [1]. This would be an enormous achievement.

Lindsey has said that the technology at the facility means that “we’re leading players” in the effort to further the understanding of this subject area [1].

Why would the ability to regrow teeth be helpful?

So why is there so much interest in regrowing teeth? There are many reasons why scientists have ploughed significant resources into this area.

Tooth loss is very common. For example, approximately 180 million Americans are missing at least one tooth, which underlines the scale of the issue [2].

Tooth loss can result in difficulties in chewing and swallowing, while it can also negatively impact self-esteem. Being able to regrow teeth would stop this.

Dental implants are an excellent solution to missing teeth. However, they are very expensive, meaning that not everyone can afford them.

It would also mean that those who have lost teeth through extensive decay, advanced gum disease, trauma or through an illness, would be able to regrow their teeth.

Furthermore, the ability to regrow teeth would help many people who have a physical illness which results in malformations in teeth growth. For example, children with a condition called congenital tooth agenesis often have teeth missing, so this could certainly help them.

Finally, the ability for teeth to regrow would save money for hospitals and lower the number of people needing treatment.

Summary

This facility is certainly exciting. There is certainly a lot of potential for the research to yield findings that could one day lead to knowledge on how teeth could regrow.

Moreover, the facility is also helping out with research into physical health too, with the researchers looking at how these fish are capable of regenerating tissues after serious injuries.

As discussed above, there are many reasons why the ability to regrow our teeth would be helpful. This is an important objective of this facility.

Hopefully the research over the next few years will contribute towards the completion of this goal, which would be an incredible and major achievement in healthcare.

Thinking points…

1) While the possibility of teeth regrowing naturally may one day become a reality, realistically this is unlikely to happen soon. Therefore, remember to take excellent care of your oral health! One way of doing this involves attending regular dental check-ups. These allow a dentist to take a look at your oral health in detail and carry out an examination. We recommend booking an appointment now!

2) It is common to be missing a tooth, or multiple teeth. If you are in this situation, a great option can be implants! Dental implants look natural, provide long-lasting results, and can improve your self-esteem. Here at our Calgary dental clinic Savanna Dental, we offer free implant consultations. These consultations offer you the chance to review potential options, you can read more about this at our website – https://savannadentalclinic.ca/!
