Frequently Asked Questions About Dental Sealants (and Their Answers!)

Even with regular brushing and flossing, some areas of your child’s mouth are harder to keep clean—especially the grooves and pits on their back teeth. These areas can easily trap food particles and bacteria, making them more vulnerable to cavities. Dental sealants offer an extra layer of protection to help prevent decay and keep your child’s smile healthy for years to come.

If you’re curious about how sealants work or whether they’re right for your child, here are answers to some of the most common questions parents ask.

What Are Dental Sealants?

Dental sealants are thin, protective coatings applied to the chewing surfaces of the molars and premolars. They act as a physical barrier, sealing out food and plaque from the deep grooves where toothbrush bristles can’t always reach.

Sealants are made from a safe, tooth-colored material that bonds to the enamel, making them virtually invisible once placed. The process is quick, painless, and requires no drilling or removal of tooth structure.

Why Are Sealants Important for Children?

Children and teenagers are especially prone to cavities in their back teeth because they are still learning proper brushing techniques and tend to eat more cavity-causing snacks. Sealants provide an extra defense during these critical years of oral development.

According to the American Dental Association (ADA), sealants can reduce the risk of decay in molars by nearly 80 percent. This makes them one of the most effective preventive treatments available for young patients.

How Are Sealants Applied?

The process of applying dental sealants is simple and can usually be completed in one visit. First, the dentist will clean and dry the tooth surface. Then, a mild solution is applied to help the sealant bond properly. After rinsing and drying again, the sealant material is painted onto the tooth and hardened with a special curing light.

The entire procedure is comfortable and typically takes only a few minutes per tooth. Once in place, the sealant immediately starts protecting the enamel from decay.

How Long Do Sealants Last?

With proper care, dental sealants can last for several years before needing to be replaced. Your child’s dentist will check the sealants at each routine visit to make sure they’re intact and providing effective protection.

Even though sealants are durable, they don’t replace daily brushing, flossing, and regular dental checkups. Think of them as an added layer of protection to reinforce good oral hygiene habits.

Are Dental Sealants Safe?

Yes. Dental sealants have been used safely and effectively for decades. They are approved by the American Dental Association and the U.S. Food and Drug Administration (FDA) for preventive dental care. The materials used in sealants are biocompatible and release no harmful substances once cured.

If you have concerns about sealant ingredients or how they might affect your child’s teeth, your dentist can discuss the materials used and answer any specific questions you have.

When Should My Child Get Sealants?

Dentists usually recommend applying sealants as soon as the permanent molars come in—typically around ages six and twelve. However, some younger children may benefit from sealants on baby teeth if they have deep grooves that are prone to decay.

Getting sealants early helps protect teeth during the years when children are most vulnerable to cavities.

Dental sealants are a quick, effective, and affordable way to safeguard your child’s smile for the long term.
