is a sealant?
A sealant is a plastic that is bonded to the biting surface of the tooth
so that food cannot sit on the tooth creating conditions for a cavity. They
are placed by the hygienist because no tooth structure has to be removed.
Bonding means that the plastic is chemically attached to the underlying
tooth structure. Though fluoride has virtually eliminated cavities for those
children taking it properly, it does not work as effectively on the grooves
on the biting surface of the molars (where the cookies stick) and this is
why sealants are necessary.
Unless you are a patient of Dr. Landin's and have seen him very recently, this should not be construed as dental advice but only as information. Please consult your own dentist in regard to your personal situation or condition.
