Sealants: A Barrier Against Decay

Sealants help prevent cavities by creating a protective barrier on the biting surface of back teeth. The biting surface of molars have deep pits, fissures, crevices, and grooves that act as natural plaque traps. Toothbrush bristles fail to fully clean these areas. By filling in and bonding to these grooves, sealants provide a tooth-colored barrier that protects the molars and effectively blocks plaque and bacteria. They are most often placed on permanent molars soon after they erupt, although they may be applied at any age on teeth with deep grooves that are susceptible to decay.
