One of the easiest procedures a dental office can provide to help minimize the risk of tooth decay, specifically in the grooves on the chewing surfaces of the permanent back teeth, is to place a clear sealant into those deep pits and fissures. This inexpensive and painless procedure involves first cleaning out any debris in the grooves, then cleansing the tooth with a mild etchant, and finally, placing a liquid resin into the grooves. Once this resin hardens, it seals access to the inside of the grooves from sugars and acids which contribute to enamel breakdown, thereby providing an extra layer of protection.
