Sealants can dramatically reduce the number of cavities a child might develop over the course of their childhood. On the chewing surface of molars, deep grooves run into the center of the teeth. Under a microscope, these crevices might look like a deep canyon. In fact, most of them are narrower than a single toothbrush bristle but wide enough for bacteria to hide. It's easy to see how cavities can form in such a perfect hideout.
If the grooves in permanent molars are sealed at a young age, the risk of decay occurring on the chewing surfaces decreases dramatically. Fortunately, your dentist can do this procedure quickly and without any discomfort or anesthetic. The sealant material creates a smooth surface, filling in the grooves, making the biting surface easier for little hands to keep clean. A resin material is flowed over the grooves and sealed quickly with a blue activating light. Within a few minutes, your child’s teeth are protected against cavities.
