Think of a dental sealant as the first line of defence against tooth decay and potential cavities. During your annual oral health exam, your dental technician at your ‘dental clinic near me’ might notice a minor lesion on one of your teeth that isn’t quite a cavity but still opens up the area for potential bacteria to infect the area and cause serious tooth decay.

How a Dental Sealant Works

The goal of a dental sealant is to shield your tooth’s surface from bacteria and germs that could penetrate through the tooth and into the sensitive tooth pulp. Even if the lesion on your tooth is tiny, it only takes a millimetre of space to allow an infection to invade the area, which is why a resin-based dental sealant is beneficial as a preventative dental treatment option. This protective material will fill in any cracks or minor chips in the tooth’s surface to keep it smooth and protected from infection.
