Your back teeth (the molars and pre-molars) have very deep grooves on their chewing surfaces, and they can be so small and narrow that cleaning them yourself at home is basically impossible. Over time, bacteria and plaque can easily build up in these tiny spaces, leading to decay that is very difficult to detect until it is far along. With dental sealants, however, we can easily stop this from happening. They involve placing a thin resin over the teeth that literally shields them from all cavity-causing factors.
The procedure to get a dental sealant is quick and 100% painless, taking only about 10-45 minutes depending on how many teeth are being sealed. It’s an easy addition to a standard checkup and a great treatment for younger patients who are still learning how to brush properly. They cost less to get than a filling, and they can easily last for a decade or more. They will eventually wear down as the years go by, but they can be easily replaced when needed during routine exams.
