The first place decay occurs in permanent teeth is on the chewing surface of back molars. This is due to deep grooves, which trap food and germs. A SEALANT is a plastic coating that is bonded into these deep grooves to lessen the chance of decay developing. A sealant is effective only if placed before any decay develops
The average life of a sealant is usually 3 years; they are plastic and wear off with eating over time. Many dental insurance companies cover the cost of sealants since they are considered preventive…you may want to check your insurance for coverage.
