Preventive Sealants

A sealant is a thin tooth colored protective coating that is placed on a tooth. The sealant starts as a liquid that flows down into the tiny, difficult to clean, grooves of a tooth. When the sealant material is just where we want it, we use a curing light to harden the sealant. The now hard sealant is smooth, and much easier to clean, helping to protect the tooth from food collecting in the grooves causing decay.
