What are sealants and does it hurt to have them?
Studies show that well more than half the cavities in children between ages of 5 to 17 are found on deep pits and grooves of tooths chewing surface. Unfortunately, fluoride, a major anti-cavity mineral, only protects the smooth surface, so the groovy surface needs another protection called a “sealant”. Sealants are opaque or clear plastic applied to the fissures painlessly to keep out food and germs. Although sealants can last long time, they should be checked at follow-up visits by your dentist to see if they need to be repaired or replaced.
