It flows down into the crevices to form a protective barrier and is cured with a halogen light. The sealant is now bonded to the tooth and is hard enough to chew on. Sealants are not foolproof. The sealant on a tooth can chip or wear off in some areas, but usually stays over the crevice part of the tooth it needs to protect. I wish all insurance companies paid for sealants, because they are quick, easy, and can prevent the need for fillings, which are far more traumatic for the children.
Sealants cost about one third the price of a small filling.
Unfortunately, most insurance companies do not cover the cost of sealants but most of us want what's best for our children. Sealants are a good investment in your child's dental health.
