Best dental clinic in Adambakkam | Pit and Fissure Sealants – A Simple Way to Prevent Cavities Pit and fissure sealants are thin, protective coatings applied to the grooves of back teeth to prevent tooth decay. These sealants act as a barrier, blocking food and bacteria from settling in hard-to-clean areas. Ideal for children and teens, sealants are a painless, quick, and effective preventive dental treatment. At Dr. Akkshaya Dental and Aesthetics in Adambakkam, we recommend sealants as part of a proactive oral health plan. They are especially useful once the permanent molars erupt, usually between ages 6 and 14. Protect your child’s smile early and avoid costly treatments later.
