What is Fluoride Varnish?

Have you heard of fluoride varnish? This preventive treatment helps strengthen and protect teeth, reducing risk of tooth decay. Next time your child is at the dentist, or even at your pediatrician, you may want to ask about a fluoride varnish.

We know that fluoride is good for teeth, and we can get it in many ways. From fluoride toothpastes and mouth rinses (which you should use daily), to drinking water, regular fluoride intake is an important component of good oral health habits.

Fun fact: Fluoride is even present naturally in many foods and drinks, like bananas, avocados, coffee, wine, shrimp, and more.

So, what is a fluoride varnish?

Simply put, fluoride varnish is a more concentrated form of fluoride, painted onto the top and sides of a patient’s teeth. The varnish itself is not a permanent layer—it stays on a patient’s teeth for several hours, allowing the fluoride to seep into the enamel and strengthen the teeth. To visualize the process, it may help to understand how fluoride works in the first place.

The outer coating of your teeth, the enamel, is the hardest substance in your body, even stronger than your bones. But that protective layer gets weakened and eaten away when we consume foods and beverages high in sugars and carbohydrates, leading to tooth decay and cavities.

When fluoride is introduced, through toothpastes, mouth rinses, drinking water, varnish, or other sources, it actually works to “remineralize” your enamel. Additionally, before tooth decay even occurs, fluoride acts to further strengthen enamel, adding additional protection down the road.

To sum it all up, a fluoride varnish is a great way to add a serious layer of protection to your teeth, which can help you avoid costly dental procedures in the future.

Who can get a fluoride varnish?

Fluoride varnishes are mainly used for children, but the truth is that anyone at risk of tooth decay could benefit from the preventive treatment. However, most insurers, including Medicaid, only cover fluoride varnish for children. In North Carolina, in response to the COVID-19 pandemic, children on Medicaid can receive a fluoride varnish a maximum of once every three month period.

Given topical fluoride varnish’s important protective benefits, it will be important that Medicaid permanently adopt policies to reimburse fluoride placement for all age groups, even after the pandemic.

If you are an adult and are interested in a fluoride varnish, have a conversation with your dentist—they can likely help you find out if your insurance will help pay for it.

A similar treatment: dental sealants

Similar to a fluoride varnish, dental sealants create a protective layer to ward off tooth decay.. Unlike a varnish, sealants are actually semi-permanent (they do wear off eventually), sealing off grooves in your teeth and providing a protective layer against foods and drinks that can cause decay.

While fluoride varnish must be applied several times each year to be effective, sealants on children’s teeth are effective up to nine years, though they should be checked by a dentist regularly as they can wear away.

The bottom line

At the end of the day, dental sealants and fluoride varnish are two effective preventive treatments that are powerful tools to prevent tooth decay and costly dental treatments necessary to repair damaged teeth.

Unfortunately, we don’t live in a world where everyone who could benefit from preventive treatments can access them. If you have access to a dentist, they can work with you to identify the mix of preventive measures that best fits your needs.

Teaching Equity in Dentistry

MLK Jr Quote: "Of all the forms of inequality, injustice in health is the most shocking and the most inhumane because it often results in physical death"

When creating equitable health care systems, especially at a statewide level, policy plays an important role in driving sustainable, system-wide change. Before policy can be implemented, however, advocates must start by changing peoples’ mindsets.

We recently sat down (virtually) with Dr. Sylvia A. Frazier-Bowers to discuss her role as Assistant Dean of Inclusive Excellence and Equity Initiatives at the University of North Carolina Adams School of Dentistry. Dr. Frazier-Bowers’ goal entering her position was to be an advocate working to change the mindsets of stakeholders when it comes to equity. Her goal was to teach people to be conscious of inclusivity and equity, which is now being incorporated into the Adams School of Dentistry’s curriculum.

“Equity refers to fairness,” said Dr. Frazier-Bowers, speaking about the importance of the word equity in health care and how it differs from the word “equality.”

While equality means treating everyone the same, or providing the same inputs into a system, equity means providing everyone with the resources and assistance they need to achieve successful outcomes. Equal treatment is important, but in a world where we are all different, with different experiences, abilities, disabilities, and resources available for our use, we inherently need different things in order to be successful. When all stakeholders have the opportunity to be successful, everyone benefits.

It is no secret that historically, people in the United States have been discriminated against because of race. While we have undoubtably made huge strides toward a more just society, the impact of historical injustice lives on, and there are still structures and individuals today who perpetuate inequity along racial lines.

For a non-oral health example of system-level equity with important ties to the dental world, see NCOHC’s interview with Duke Wold Food Policy Center Director of Strategic Initiatives Jen Zuckerman.

Dr. Frazier-Bowers explained that if two groups are given the same amount of a given resource, one may still be at a disadvantage if they started out further behind. When it comes to health care, equity may actually mean giving some people more help just to overcome existing disparities.

The Adams School of Dentistry curriculum is currently being revised, and the Office of Inclusive Excellence and Equity Initiatives is working to incorporate equity education into the dental school’s coursework.

“Instead of having an insular experience of, ‘Okay everyone, we’re now going to learn about equity and justice,'” said Dr. Frazier-Bowers, “It’s going to be integrated more seamlessly throughout the four-year curriculum.”

Working with experts in equity and justice education, the school designed the Advocate, Clinician, and Thinker (ACT) framework to integrate knowledge of racial equity throughout the four years of schooling, rather than as a small section.

To further incorporate equity education into the student experience, the Adams School of Dentistry was the first to coin an Inclusive Excellence Week, offering weeklong experiences to promote equity. Working with a community of scholars from different disciplines, the Adams School of Dentistry is able to communicate regularly with content experts who can influence new ideas and portray the interconnectedness of their work. The Adams School of Dentistry’s Inclusive Excellence Week influenced dental schools at other universities to do the same.

According to Dr. Frazier-Bowers, when it comes to equity and inclusion, “Mindset is the key.”

“When I say the mindset, this refers to every time you engage in any activity,” said Dr. Frazier-Bowers. “Whether its teaching, seeing patients, being a student, or being a classmate even—think about it from a lens that considers inclusivity and equity.”

When asked about the most prevalent social injustices in dentistry, Dr. Frazier-Bowers explained how the fact that not everyone has access to reliable care is an issue. Unlike a second home or expensive car, “education and health care should not be considered luxuries,” she said.

For that reason, the Adams School of Dentistry is currently working on self-assessment and accountability measures where people can have an opportunity to reflect and search for improvement in the pursuit of equity.

“People must be willing to open their minds to truth and history,” said Dr. Frazier-Bowers.

Many oral health professionals already advocate for change and understand what needs to be done to create a lasting impact. For those who don’t, there are always ways to get involved, but you have to be willing to put in the work. The DOCSpeaks program was created by Frazier-Bowers to bridge the “knowing-doing” gap for well-meaning professionals.

According to Dr. Frazier-Bowers, it all starts with education and an open mindset. The UNC DOCSpeaks sessions are a resource that can serve as a good starting point, and they will soon be open to the public. Outside of the education system, any community with the right leaders and the right mindset can be a catalyst for racial equity.
