Used for decades by dental professionals, sealants are applied like a thin coat of paint onto the teeth and then hardened using a special dental curing light. The chewing surfaces of molars and premolars, located in the back of your mouth, are full of fissures and ridges which make them particularly good areas for bacteria to hide. It is not easy to clean these teeth effectively with only a toothbrush, which is why it is important to get regular cleanings and consider getting a teeth sealant at Green Tree Dental.
