Dental sealants provide a physical barrier that helps prevent bacteria and food particles from settling into the pits and fissures of the teeth. By sealing these vulnerable areas, dental sealants reduce the risk of tooth decay and cavities.

Sealants are most commonly recommended for children and teenagers as soon as their permanent molars and premolars erupt. However, adults who have deep grooves and pits on their teeth and are at a higher risk of developing cavities can also benefit from sealants.

Sealants can last several years before they may need to be reapplied. Regular dental check-ups are essential to monitor the condition of the sealants and ensure they remain intact. If a sealant becomes chipped or worn, it can be repaired or replaced by a dental professional. Proper oral hygiene, including regular brushing, flossing, and routine dental visits, is still necessary even with dental sealants to maintain overall oral health.
