Dental sealants are a type of special coating that act as a barrier, protecting cavity-prone teeth. They are usually applied to the chewing surfaces of back teeth. They are sometimes used to cover deep pits and grooves in other teeth. As long as the sealant remains intact, the tooth surface will be protected from decay. Applying sealants during childhood will protect the teeth throughout the most cavity prone years. Sealing a tooth is fast and easy. Sealants can last for many years if properly cared for, and will last longer if you maintain good oral hygiene and avoid biting hard objects. During routine dental visits your dentist will check the sealants and may recommend reapplication or repair when necessary. Ask your dentist about sealants today.
