If you’re the parent of early elementary-aged children, you’ll likely hear your pediatric dentist mention dental sealants. Dental sealants are a very effective way to protect your child’s teeth. They work by forming a protective barrier on teeth, filling small grooves, pits, and fissures where bacteria can live but toothbrush bristles are too big to reach.

Sealants are usually recommended once the first molars grow in at around age 6 years old, and when the second molars grow in at around age 12. Sealants may also be recommended for older patients who are at risk of developing cavities. Placing sealants is typically a quick, easy, and painless procedure.

Here’s what you can expect – First the teeth are thoroughly cleaned then a specialized sealant liquid is painted on the teeth followed by a short exposure to a bright cure light to harden the liquid. This forms a smooth, hard barrier to keep food and bacteria out of the teeth. A one-time sealant application will often last at least a couple of years and with proper care it is not uncommon for sealants to help prevent decay for up to 10 years. Proper care would include regular check ups for fracturing and wear, possible minor touch ups, as well as good oral hygiene habits at home.

According to the CDC, sealants can prevent 80 percent of cavities in back teeth, which is where 9 out of 10 cavities occur. Prevention is especially important in young children because once a permanent tooth has a cavity and is restored with a filling, that filling will have to be replaced many times over the child’s life. And as these children grow into adults, these fillings can also often need to be replaced with larger fillings or eventually crowns. Stopping the cascade of disease and progression to more invasive dental needs with the help of sealants is essential for long term oral health.

Sealants are a great way to reinforce the importance of dental care without being a substitute for regular brushing twice a day and regular flossing. They are also often covered by insurance and if not, the costs are usually very reasonable, especially compared to the cost a dental filling. Since cavities can lead to more serious dental issues, sealants are a valuable investment in your child’s health and smile.

Your child’s pediatric dentist can answer any question you may have relating to dental sealants – or any other concerns about your child’s oral health. If you don’t have a relationship with a pediatric dentist yet, use the AAPD’s “Find a Dentist” tool to locate one near you.
