Pit and fissure sealants are treatment to prevent tooth decay.
The chewing surfaces of the teeth have grooves/fissures that make them weak to decay. These fissures can be deep, are difficult to clean, and can be narrower than even a single bristle of a toothbrush. Food and Plaque accumulate in these areas, and the acid from bacteria in the plaque attacks the enamel and cavities can develop. Dental sealants provide extra protection for the grooved and fissure areas by providing a smooth surface. Dental sealants are used to fill these pits to provide a smooth surface that is easy to clean and maintain.
