Seal Out Decay with Sealants
A sealant is a plastic material that is usually applied to the chewing surfaces of the back teeth (premolars and molars). This plastic resin bonds into the depressions and grooves (pits and fissures) of the chewing surfaces of the back teeth. The sealant acts as a barrier protecting the enamel from plaque and acids which cause decay (cavities).
The surfaces of the back teeth are difficult to keep clean, because they cannot be reach with a toothbrush. It is for this reason that sealants are indicated (i.e., needed) while the back teeth are developing. Sealants keep out plaque and food and, thereby, decrease the risk of decay. Prevention is always preferable to treatment. Because sealants are extremely effective in preventing pit and fissure decay, properly applied they can result in savings, both in dollars and in discomfort.
