Your back teeth have small grooves called pits and fissures on their biting surfaces that can become traps for foods and liquids that contain sugar. The sugar can be converted into acid by resident bacteria in plaque and demineralize the tooth surface, causing a cavity. Dental sealants are thin, plastic coatings that can be applied to these grooves. This coating projects the chewing surfaces from tooth decay by keeping bacteria and food particles out of the grooves.
