Dental sealants are thin layers of resin applied to the pits, fissures, and grooves of molars to prevent tooth decay. The majority of decay on back teeth begins in these hard-to-clean areas, especially during the first few years after the teeth erupt.

By sealing these vulnerable surfaces with composite resin, sealants act as a barrier against bacteria and food particles, significantly reducing the risk of cavities. While decay may still develop between teeth, sealants are one of the most effective ways to protect chewing surfaces from cavities and maintain long-term oral health.
