When it comes to protecting your teeth and maintaining good oral health, the most important thing to do is brush often and floss daily. However, brushing and flossing your teeth is just the beginning. It is easy to overlook the back teeth, or molars, and even though you may be brushing regularly, the chewing surfaces of those back teeth don’t always get as clean as they need to be. This is because of the fissures or “pits” in the molars and premolars that allow food particles to build up where toothbrush bristles may not reach. In this case, dental sealants may be recommended by your dentist.
