The newest research by the CDC reveals that low income children with sealants has increased by 70% preventing nearly 1 million cavities. This proves that sealants play a pivotal role in keeping children’s oral health in tact. Sealants are placed on the permanent molars of children. It is a liquid plastic that flows into the grooves on the occlusal or biting surface. The plastic is then hardened with a light. This creates a barrier that prevents food and bacteria from depositing deep in the groove where toothbrushes cannot adequately brush. While they are extremely effective, dental sealants are not permanent and can wear off. It is essential that you ask your dentist to examine these for replacement at every cleaning appointment. Insurance coverage will vary for this procedure so as a patient it is in your best interest to know what your benefits specify.
