When it comes to protecting your child’s teeth, every parent wants to make the safest, most informed choice. If your dentist has recommended dental sealants, you may have questions about how they work, what they’re made of, and—most importantly—whether they’re truly safe for your child.
The good news? Dental sealants have been used safely and effectively for decades, and they remain one of the simplest ways to prevent cavities in children and teens. In this post, we’ll break down what dental sealants are, how they’re applied, and why parents can feel confident choosing them.
What Are Dental Sealants?
Dental sealants are thin, protective coatings—usually made from medical-grade resin—applied to the chewing surfaces of the back teeth (molars and premolars). These are the areas most vulnerable to decay because of their deep grooves and pits, which can trap food particles and bacteria.
Once applied, sealants act as a barrier that keeps out plaque and food, reducing the risk of cavities. They’re especially beneficial for children and teenagers, whose newly erupted permanent teeth are still developing and more prone to decay.

Are Dental Sealants Safe?
Yes—dental sealants are considered extremely safe for children, teens, and adults. In fact, both the American Dental Association (ADA) and the Centers for Disease Control and Prevention (CDC) recommend sealants as a proven tool for cavity prevention.
However, some parents have questions about one particular component: BPA (bisphenol A), which may be present in trace amounts in some sealant materials.
What About BPA?
- While it’s true that some dental sealants contain very small traces of BPA, research shows that the levels are far below any threshold considered harmful.
- According to the ADA, exposure to BPA from sealants is 100 times lower than daily exposure from food, water, or air.
- In most cases, BPA levels from sealants are undetectable after 24–48 hours.
If you’re concerned, speak with your dentist. Many modern sealants are now BPA-free, and your provider can choose a material that meets your preferences.
Benefits of Dental Sealants for Children
Still on the fence? Here are a few reasons why dental sealants are widely recommended by pediatric and family dentists alike:
- Cavity Prevention: Sealants reduce the risk of decay by up to 80% in molars.
- Pain-Free Application: No drilling or numbing needed—it’s a quick, non-invasive procedure.
- Cost-Effective: Preventing a cavity is far less expensive than filling one.
- Long-Lasting: With proper care, sealants can protect teeth for up to 10 years.
Who Should Get Dental Sealants?
Sealants are especially recommended for:
- Children around age 6, when their first molars appear
- Children around age 12, when their second molars erupt
- Teens and adults with deep grooves or a history of cavities
Even adults can benefit from sealants if they have healthy molars without existing fillings.
What to Expect During the Procedure
The sealant application process is simple and painless:
- The tooth is cleaned and dried
- A gentle etching solution is applied to help the sealant bond
- The sealant is painted onto the tooth
- A special light hardens the sealant in seconds
Your child can eat, drink, and return to normal activities immediately after the appointment.
Conclusion: A Safe, Smart Choice for Preventive Care
Dental sealants are one of the easiest ways to protect your child’s smile for the long haul. Backed by decades of research and trusted by dental professionals across the country, sealants are a safe, cost-effective way to prevent cavities—especially during those vulnerable early years.
