Molars (teeth at the back of the mouth used for chewing) often have grooves or fissures. These can be difficult to clean and food particles can be trapped here. Bacteria may grow and release acids that can decay your tooth. Your dentist can apply a protective plastic covering (sealant) to the fissure to help prevent tooth decay.
