What is the primary purpose of dental sealants?

The primary purpose of dental sealants is to prevent tooth decay. Sealants are thin, protective coatings that are applied to the chewing surfaces of molars and premolars, particularly in children and teenagers who are at higher risk for cavities. These surfaces have pits and fissures that can trap food particles and bacteria, leading to decay. By sealing these areas, sealants create a smooth surface that is easier to clean and less likely to accumulate plaque, thereby significantly reducing the risk of cavities and supporting overall oral health. This preventive measure is particularly beneficial in maintaining the health of developing teeth and is a widely recommended practice in pediatric dentistry.
