If you’ve ever considered dental sealants for yourself or your child, you may have stumbled across concerns about BPA. It’s a hot topic—and understandably, any material used in your mouth should be safe and well-studied.
That’s why patients looking for guidance often turn to the best dentists in Palm Beach Gardens, who can separate fact from fiction with clarity and care. It’s best to uncover the truth behind BPA in dental sealants and explore why this powerful treatment remains one of the most effective methods for preventing cavities.
What Is BPA and Why Is It in the News?
Bisphenol A (BPA) is a chemical commonly used in the manufacturing of plastics and resins. It gained attention for its possible effects on hormone regulation and health, especially when used in food packaging. This naturally raised questions about its presence in dental materials—including sealants. But here’s what you need to know.
Myth #1: “Dental sealants are full of BPA.”
Fact: Dental sealants do not contain BPA as an ingredient.
Most dental sealants are made from BPA derivatives, such as bisphenol A diglycidyl ether (Bis-GMA) or bisphenol A dimethacrylate (Bis-DMA), which differ in their chemical structure and behavior. While trace amounts of BPA can be detected as a byproduct when Bis-DMA-based sealants degrade, this is usually a temporary and minimal occurrence, often comparable to everyday exposure from handling receipts or using plastic containers.
Myth #2: “BPA exposure from sealants is dangerous.”
Fact: Exposure levels are extremely low—far below health risk thresholds.
Studies have shown that the release of BPA from dental sealants is extremely low and occurs only for a short time after placement. According to the American Dental Association (ADA) and the U.S. Food and Drug Administration (FDA), these levels are not considered harmful. For context, you'd be exposed to more BPA by touching a grocery receipt than from getting dental sealants.
Myth #3: “There are no safe alternatives.”
Fact: BPA-free and ultra-low BPA sealant options are widely available.
If you’re still concerned, speak to your dentist. Many practices offer sealants formulated without BPA derivatives or with the lowest release potential. Pediatric and family dentists often stock multiple material types to suit specific health preferences or sensitivities.
Myth #4: “Sealants aren’t necessary anyway.”
Fact: Sealants reduce cavities in molars by up to 80%.
Skipping sealants because of BPA myths could do more harm than good. Sealants are applied to the chewing surfaces of back teeth to “seal out” plaque and food particles. The CDC and ADA both endorse them as a proven, safe, and essential step in preventive dental care, particularly for children and teenagers.
Myth #5: “Adults don’t benefit from sealants.”
Fact: Sealants aren’t just for kids.
While most often applied to children’s newly erupted molars, adults can benefit too—especially those prone to decay, deep grooves, or sensitivity. Your dentist may recommend them during your next cleaning or preventive visit, particularly if you've a history of cavities.
