With the eruption of the permanent 6 and 12 year molars, we
start discussing dental sealants with parents. Sealants are a relatively easy
preventative procedure. It takes about 10 minutes from start to finish. Many
parents have researched dental sealants and may be concerned about to
introduction of BPA. Our sealants are BPA free. The list of BPA free sealants,
compiled by the ADA, is listed below. The brand we use is Clinpro (3m ESPE). We
hope this blog helps answer any questions you may have.
What are Sealants?
A sealant
is a flowable liquid we apply to the chewing surface of molars to aid in the
prevention of cavities. It acts as a barrier to food, plaque, and acid. Thus,
it protects the decay-prone areas of the teeth. Sealants will not protect your
child from getting decay in between the teeth. Therefore, regular brushing and
flossing is still strongly recommended.

How do Sealants work?
Ensuring
that your child is brushing and flossing properly is a tough job. When their
permanent molars begin to erupt, the pits of these teeth are deeper than most.
Sometimes, even if your child is brushing and flossing like they should, these
deep grooves aren’t getting clean. This is where sealants come into play. They
“seal” the biting surface of a molar in order to prevent plaque and food from embedding
into the grooves, decreasing the risk of decay.
How are sealants
applied?
We
start by “etching” the tooth. This process preps the tooth, allowing it to
retain the sealant. Next we bond the tooth. The bond acts as an extra measure
to ensure the sealant stays on. Afterwards, the sealant is placed. Similar to
having a filling done, a UV light is used to harden the sealant. During this
process, we isolate the tooth to prevent your child from swallowing any of the
materials.
How long do they
last?
If
cared for properly sealants can last for years. Your dentist should check them
at every 6 month visit. Repair and re-application may be recommended if
necessary.
