Sealants are an easy and effective way to help protect your back teeth (molars) from cavities and decay. These teeth do most of the chewing and can be tough to keep clean, which makes them more likely to get cavities. The first molars usually come in around ages 5 to 7, and the second set shows up between 11 and 14. It’s a good idea to get sealants on them as soon as they come in to keep them protected from the start.
Getting a sealant is quick and painless. First, a thin layer of adhesive is put on the tooth. Then, the sealant—kind of like a liquid coating—is painted on. It hardens pretty fast and creates a shield that keeps out plaque, food, and bacteria. Sealants can last up to 10 years, and if needed, they can be reapplied.
