Dental sealants (also known as tooth sealants) can play an important part in helping prevent tooth decay on some areas of the teeth. Tooth decay is caused by the bacteria found in dental plaque. The longer dental plaque stays on a tooth’s surface the more likely it will be able to form a cavity. The idea behind brushing teeth is that dental plaque that has accumulated on a tooth’s surface is scrubbed off. However, some teeth have aspects related to their anatomy are harder to clean than others.
The placement of sealants involves the bonding of a plastic coating into the grooves of your tooth. The result is a smoother tooth surface, one which is less likely to trap food and plaque and one which is easier to clean with your toothbrush.
