Newly erupted molars and sometimes other teeth often have deep grooves and pits on the chewing surface of the tooth. Food and bacteria tend to get stuck in these deep grooves and pits and can cause cavities. Sealants help to prevent cavities by filling in these grooves and pits. Sealants are non-invasive and simple to place. Sealants have been shown to reduce the number of cavities on the chewing surface of the tooth by 76%. Sealants will be recommended as soon as the permanent molars erupt and may be recommended on other teeth based on your child’s risk for cavities.
