Sealants are the #1 way of preventing decay for teens and children, and also benefit adults as well. It's a plastic material that is applied on the chewing surface of the back teeth. It acts as a barrier, protecting the enamel from plaque build-up and acid. Sealants become necessary when the back teeth are developing, because of the pits and fissures that form in the chewing surfaces of the tooth. The lack of ability for a toothbrush to reach down into the pits to clean them causes build-up of plaque and food that cause decay if not taken care of. Each sealants takes only a few minutes to seal and last several years before any reapplications are needed.Check out Dr. Dennis Myers' webiste at stjoesmiles.com or troysmiles.com to schedule an appointment. Dr. Myers checks at every regular dental appointment for need of sealants and keeps them maintained until reapplication is necessary.
