Dental Varnishes protect teeth

Dental Varnishes are an important part in the fight against tooth decay. For places that do not have fluoride in their water, dental varnishes can make a significant difference in the amount of tooth decay present.


In Chariton County Missouri, according to the local health department, areas of the county without fluoride in the water had a dental screenings referral rate of more than double areas with fluoride in the water when screenings were conducted at the local schools. While the referrals did not necessarily mean that there was a definitive problem, it did indicate that there was the potential for a more serious issue and follow up care was necessary.

According to the American Academy of Pediatric Dentistry, children should begin to receive dental care when their first tooth appears or no later than their first birthday. By age six the permanent teeth begin to erupt. These permanent teeth need to be protected from dental cavities. Dental varnishes are just one tool used in prevention of dental cavities however, they are only meant to be part of a team approach that also includes regular visits to a dentist.

According to the American Academy of Pediatrics, dental varnishes consist of “5% sodium fluoride or 2.26% fluoride in a viscous resinous base in an alcoholic suspension with a flavoring agent (e.g. bubble gum)” (http://www.aap.org/oralhealth/cme/page46.htm). This solution should be applied by a dental professional. It is applied to the surface of the teeth and is used to prevent further cavities from forming. It can also help to strengthen teeth and reverse early stages of demineralization as it begins to occur.

It is important to note that dental varnishes do not replace regular dental checkups by a dental professional nor do they replace at home care. They are simply a supplement to help defend against cavities. They are particularly important for areas that do not have fluorinated water.

While some may argue that this additional fluoride will lead to fluorosis, according to the American Academy of Pediatrics website it does not. There is evidence from Scandinavia that this treatment is effective as it has been used there for more than 25 years.

Other important parts of dental care are establishing a dental home, which is similar to the concept of a primary care physician in the fact that the dental home establishes care and preventative measures. Other important habits include proper brushing and flossing.

In conclusion, dental varnishes are an important part in the prevention of dental tooth decay, especially for areas that lack fluoride in the drinking water. Dental varnishes do not replace regular dental care by a dental professional, but are a supplement to further help protect a child’s teeth.
