How do sealants work?
A. In many cases, it is near impossible for children to clean the tiny grooves in their teeth. When a sealant is applied, these grooves are filled in, and the surface of the tooth becomes flatter and smoother. There are no longer any places on the chewing part of the tooth that the bristles of a toothbrush can’t reach and clean. Since plaque can be removed more easily and effectively, there is much less chance that decay will start.
