Dental sealants are a preventive dental treatment that involves applying a thin, protective coating on the chewing surfaces of the back teeth (molars and premolars). These teeth have grooves and pits that can trap food particles and bacteria, leading to tooth decay. Sealants act as a barrier, sealing off these vulnerable areas and preventing the buildup of plaque and bacteria. The application process is quick, painless, and non-invasive. Dental sealants are particularly beneficial for children and teenagers who are prone to cavities but can also be used for adults. They are an effective way to protect teeth and reduce the risk of dental decay. Regular dental check-ups are still necessary to ensure the sealants are intact and providing adequate protection.
