How Dental Sealants Create a Protective Barrier on Teeth Dental sealants are one of the simplest ways we help protect teeth from decay. Sealants are thin, protective coatings placed on the chewing surfaces of molars and premolars, where deep grooves can easily trap food and bacteria. At Tulane Family Dentistry, we often recommend dental sealants as part of a preventive dental care plan for both children and some adults. Why Back Teeth Need Extra Protection The back teeth do most of the heavy chewing, and their uneven surfaces can be harder to keep clean with brushing alone. Even patients with good oral hygiene can miss the tiny pits and fissures on molars. When plaque and food particles stay in those areas, the risk of cavities goes up. Dental sealants help by covering those vulnerable spots before decay starts. How Sealants Form A Barrier A dental sealant works by bonding to the tooth surface and creating a smooth shield over the natural grooves. Once in place, the sealant helps block out food debris, plaque, and bacteria that could otherwise settle into hard-to-reach areas. This protective barrier makes the tooth easier to clean and lowers the chance of cavities developing in the future. What The Application Process Looks Like Getting dental sealants is quick, comfortable, and non-invasive. We begin by cleaning and drying the tooth. Then we prepare the surface so the sealant material can bond properly.
