Sealants A sealant is a plastic material that is usually applied to the chewing surfaces of back teeth—pre-molars (bicuspids) and molars. The depressions and grooves (pits and fissures) of the chewing surfaces of back teeth can be extremely difficult to keep clean. Some of the pits and fissures are so narrow and deep that the bristles of a toothbrush cannot reach into them. These areas are snug places for plaque and bits of food to hide and are especially prone to decay. The sealant - a plastic resin - bonds into the grooves and acts as a barrier, protecting enamel from plaque and acids. Sealants have been shown to stop more than 80% of dental decay within two years of application. They offer a great, painless option when looking for ways to reduce cavities in children. How are they applied? It usually takes only a few minutes to seal each tooth. The teeth that will be sealed are cleaned. The chewing surfaces are conditioned to help the sealant adhere to the tooth. The tooth must be kept very dry. The sealant is then "painted" onto the tooth enamel, where it bonds directly to the tooth and hardens. A special curing light is used to help the sealant harden. How long do sealants last? As long as the sealant remains intact, the tooth surface will be protected from decay in that area. Sealants usually last several years before a reapplication is needed. During regular dental visits, the condition of the sealant will be checked and reapplication will be done as is necessary. ‡ |
