Best dental clinic in Adambakkam | Pit and Fissure Sealants: Protecting Your Teeth Pit and fissure sealants are a preventive dental treatment designed to protect molars from cavities. These thin, protective coatings are applied to the chewing surfaces of teeth, sealing deep grooves where food particles and bacteria often get trapped. Ideal for children and teens, sealants act as a barrier against tooth decay and make cleaning easier. At Dr. Akkshaya Dental & Aesthetics, we recommend sealants as part of a proactive oral care plan to maintain a healthy, cavity-free smile.
