Dental Sealants: What Are They and Who Needs Them?

Sometimes, even the most thorough oral hygiene routine can miss those deep grooves and hard-to-reach spots. That’s where dental sealants come in. These thin, protective coatings act as a barrier against decay, and they can make a big difference in keeping teeth healthy.

At Grand Falls Smiles Dentistry, we believe in the power of preventive care. Dental sealants are one of the simplest and most effective ways to reduce the risk of cavities, yet many people don’t know much about them.

Whether you’re a parent thinking about your child’s dental health or an adult exploring ways to protect your own smile, use this post as a guide to dental sealants.

What Are Dental Sealants?

Dental sealants are a clear or tooth-coloured resin material that is applied to the grooves and pits of your back teeth (primarily the molars and premolars). These areas are the most susceptible to decay because they’re full of tiny crevices that easily trap food particles and bacteria. Even with excellent brushing, it can be difficult to clean these areas thoroughly every day.

Sealants work by creating a smooth surface over these natural grooves, preventing food and plaque from collecting there. Once applied, the sealant hardens and forms a shield that can last several years.

How Are Sealants Applied?

Applying a sealant is a simple, non-invasive procedure that can usually be completed in a single dental visit. First, the tooth is cleaned and dried. A special solution is then applied to the chewing surface to help the sealant bond properly. After rinsing and drying again, the dentist brushes the sealant material onto the tooth. A curing light is used to harden the sealant in place, and that’s it, you’re done!

Because the process is fast and comfortable, it’s ideal for children and teens who may be anxious about dental visits. In many cases, dentists apply sealants during a routine cleaning appointment, often around the time when the first and second permanent molars come in.

Who Needs Dental Sealants?

While anyone can benefit from sealants, they’re most commonly recommended for children and teenagers. That’s because these age groups are especially prone to cavities, and the earlier you can protect their permanent molars, the better. Typically, we suggest applying sealants as soon as the first set of permanent molars erupts (usually around age 6) and again when the second set comes in, around age 12.

But that doesn’t mean adults are left out. Adults without cavities or fillings in their molars can also benefit from sealants, especially if they have deep grooves in their teeth or are at higher risk for decay. If you’ve had cavities in the past, have dry mouth, or consume a high-sugar diet, sealants can be an extra line of defense to keep your teeth healthy.

Commonly Asked Questions About Sealants

Do Sealants Really Work?

Yes, dental sealants are proven to be effective. According to the Centers for Disease Control and Prevention (CDC), sealants can reduce the risk of cavities in molars by up to 80%. That’s a significant benefit, especially considering how quick and affordable the procedure is. Sealants are especially valuable for protecting newly erupted molars, which are more vulnerable in the early years.

It’s important to remember that sealants are not a substitute for brushing and flossing. They work best as part of a complete oral care routine that includes daily hygiene, regular dental checkups, and a healthy diet. Think of them as a safety net that helps catch what your toothbrush might miss.

How Long Do Sealants Last?

Sealants can last anywhere from 5 to 10 years, depending on factors like your chewing habits and how well you care for your teeth. During your regular checkups, your dentist will inspect the sealants and touch them up or reapply them if necessary.

Most people find that once applied, sealants stay in place for several years without issue. It’s worth noting that the application is painless and can be repeated as needed. So even if a sealant wears down over time, it’s easy to replace it and continue protecting the tooth.

Are Sealants Safe?

Absolutely. Dental sealants have been used safely for decades. Some parents express concern about the materials used in sealants, particularly around BPA (bisphenol A), but the levels found in dental sealants are extremely low and much lower than what you’d encounter from everyday objects like plastic containers or receipts.
