What are dental sealants?

A dental sealant (also called a pit and fissure sealant) is a plastic, professionally-applied material that is put on the chewing surfaces of back teeth to prevent cavities. Sealants provide a physical barrier so that cavity-causing bacteria cannot invade the teeth from the chewing surface. In presence of sealants the tooth is smoother, and therefore easier to brush.

When should my child get dental sealants?

First permanent molars erupt into the mouth at about 6 years of age. Placing sealants on these teeth shortly after they erupt protects them from developing caries in areas of the teeth where food and bacteria collect.

Second permanent molars come out at about age 12. Therefore, young teens need to be evaluated for sealant placement to help prevent decay on these vitally important teeth.

Are dental sealants just for kids?

The potential to develop cavities begins early in life, so children and teenagers are obvious candidates. However, adults who take medications, or are unable to brush their teeth properly are at higher risk of getting tooth decay, and therefore can benefit from sealants as well. Dr. Vinson can help you determine if dental sealants are appropriate in your situation.

How can fluoride treatment benefit my child?

In presence of sugar, the bacteria that are normally present inside the mouth produce acid. This acid removes minerals from the surface of the tooth, a process that is known as demineralization. If the demineralization process continues for a period of time, a cavity is formed. If fluoride is available, the tooth is able to rebuild itself, thereby preventing the cavity. In addition to being a building material for the tooth, fluoride reduces the ability of the oral bacteria to produce acid.

Do dental sealants replace fluoride?

No. Fluorides, such as those used in community water, toothpaste, gels, varnish, and mouthrinse also help to prevent decay. Fluoride works best on the smooth surfaces of teeth. The chewing surfaces on the back teeth, however, have tiny grooves where decay often begins. Sealants keep cavity-causing bacteria out of the grooves by covering them with a safe plastic coating. Sealants and fluorides work together to prevent tooth decay.
