Preventive dentistry is a vital part of dental science. It helps to prevent the onset of any oral infection even before the patient develops it, which is way better than getting it treated after it has taken a significant toll on oral health. One such part of preventive dentistry is the application of dental sealants.
Sealants are made from tooth-colored acrylic and applied on the surface of the molars and premolars to prevent cavities. The grooves on the surfaces of these teeth can house thousands of microbes though they seem just as wide as a small crack. Minute food particles and other debris may also get accumulated in them, thereby driving up the chances of getting cavities. The sealants prevent this by completely sealing off the grooves to the microbes and food particles in the mouth.
