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.
Luckily, there’s a 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.
In fact, sealants have been shown to reduce the risk of decay by nearly 80% in molars. This is especially important when it comes to your child’s dental health. In October 2016, the Centers for Disease Control released a report on the importance of sealants for school-aged children, of which only 43% of children ages 6-11 have. According to the CDC, “school-age children without sealants have almost three times more cavities than children with sealants.”
Sealants work by placing a liquid resin in the grooves of your molars to protect the grooves from catching cavity-causing food and bacteria. The procedure is quick (usually 5 – 45 minutes long based on how many sealants have to be placed).
Who can get sealants?
Both children and adults can benefit from sealants, but the earlier you get them, the better. Your first molars appear around age 6, and second molars break through around age 12. Sealing these teeth as soon as they come through can keep them cavity-free from the start, which helps save time and money in the long run. Ask your dentist if sealants are a good option for you and your family.
How are sealants applied?
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.
Is there any BPA in sealants?
Yes, there is a tiny amount of BPA in sealants but not enough to cause you or a loved one any harm. In fact, you get more exposure to BPA by simply touching a receipt, using cosmetics or coming in contact with dust.
