Sealants are a plastic resin material that is applied to the chewing surfaces of the back teeth—premolars and molars. They act as a barrier, protecting enamel from plaque and acids that contribute to dental decay. Toothbrush bristles cannot reach into the deep depressions and grooves of teeth and the sealant helps to protect these areas.
Sealants are easily applied and take only a few minutes for each tooth. Sealants will be checked at each appointment to make sure they are retained, and will generally last several years before reapplication is needed.
