Protecting your child’s smile is a lifelong commitment, and good oral hygiene habits are just the beginning. Even with consistent brushing and flossing, some areas of the mouth—especially the grooves of the molars—can be difficult to keep clean. That’s where dental sealants come in. These thin coatings provide an extra layer of defense against tooth decay. If you’re curious about how they work, here are answers to some of the most common questions parents have about sealants.
What Are Dental Sealants?
Dental sealants are thin, plastic-like coatings applied to the chewing surfaces of the back teeth. These molars naturally have deep pits and fissures where food particles and bacteria can hide, making them more prone to cavities. Once applied, the sealant forms a smooth, protective barrier that keeps plaque and acids from damaging the enamel.
Sealants are most often recommended for children, but adults who don’t have decay or fillings in their molars can benefit from them as well. They’re a simple and effective way to safeguard teeth against cavities for years at a time.
How Are Sealants Applied?
The process of applying dental sealants is quick, comfortable, and completely noninvasive. First, the dentist will thoroughly clean and dry the tooth. Then, a mild solution is applied to roughen the surface slightly, which helps the sealant bond securely to the enamel. After rinsing and drying the tooth again, the sealant material is painted onto the grooves and hardened with a special curing light.
The entire process typically takes just a few minutes per tooth, and patients can resume eating and drinking right away.
How Long Do Dental Sealants Last?
Dental sealants can last for several years before needing repair or reapplication. With good oral hygiene and regular dental checkups, they may even protect teeth for a decade or longer. Your child’s dentist will examine the sealants during routine visits to ensure they’re still intact and effective. If a sealant becomes chipped or worn, it can easily be replaced during the same appointment.
Are Sealants Safe?
Yes! Dental sealants have been used safely and effectively for decades. The materials used are approved by the American Dental Association (ADA) and undergo strict safety testing. Some sealants contain trace amounts of BPA, but research shows that the levels are far below what is considered harmful. In fact, the health benefits of preventing tooth decay far outweigh any potential risks.
Do Sealants Replace Brushing and Flossing?
Sealants are not a substitute for good oral hygiene—they’re an added layer of protection. Your child should continue to brush twice a day with fluoride toothpaste and floss daily to remove food and plaque from between the teeth and along the gumline. Sealants help shield the chewing surfaces of molars, but the rest of the mouth still needs attention to stay healthy.
Keep Cavities at Bay with Preventive Care
Dental sealants are a smart, affordable, and painless way to prevent cavities and keep your child’s smile strong as they grow. Combined with daily brushing, flossing, and regular checkups, they can make a big difference in long-term oral health.
