Brushing and flossing are the best ways to help prevent cavities, but it’s not always easy to clean every nook and cranny of your teeth – especially those back teeth you use to chew (called molars)
. Molars are rough, uneven and a favorite place for leftover food and cavity-causing bacteria to hide.
Still, there’s another safety net to help keep those teeth clean. It’s called a sealant, and it is a thin, protective coating (made from plastic or other dental materials)
that adheres to the chewing surface of your back teeth. They’re no substitute for brushing and flossing, but they can keep cavities from forming and may even stop early stages of decay from becoming a full-blown cavity.
How Are Sealants Applied?
It’s a quick and painless process. Your dentist will clean and dry your tooth before placing an acidic gel on your teeth
. This gel roughs up your tooth surface so a strong bond will form between your tooth and the sealant. After a few seconds, your dentist will rinse off the gel and dry your tooth once again before applying the sealant onto the grooves of your tooth. Your dentist will then use a special blue light to harden the sealant.
Can Sealants Be Placed Over Cavities?
Sealants can be used over areas of early decay to prevent further damage to your tooth. Because some sealants are clear, your dentist can keep an eye on the tooth to make sure the sealant is doing its job.
Some plans do cover sealants, so call your dental benefit company to find out what kind of coverage you have.
