As a parent, you want to do everything you can to protect your child’s oral health. Dental sealants are one of the most effective ways to prevent cavities in children’s permanent molars, especially during the cavity-prone years of childhood. However, some parents have concerns about the safety of dental sealants, particularly when it comes to BPA (bisphenol A), a chemical sometimes associated with plastics.
At North Shore Dental Center in Peabody, we understand that your child’s safety comes first. In this article, we’ll explain what dental sealants are, how they work, and what the latest research says about BPA exposure so you can make an informed decision for your child’s dental health.
What Are Dental Sealants?
Dental sealants are thin, protective coatings applied to the chewing surfaces of the back teeth, the molars and premolars. These areas often have deep grooves where food and bacteria can collect, making them more likely to develop cavities.
The sealant material flows into these grooves and then hardens, creating a smooth surface that’s easier to keep clean. Sealants are most commonly applied to children’s permanent molars soon after they erupt, typically between ages six and twelve.
When applied properly, sealants can reduce the risk of cavities by up to 80 percent — making them one of the most effective preventive treatments in pediatric dentistry.
Why Parents Worry About BPA
BPA, or bisphenol A, is a chemical used in the production of certain plastics and resins. It has been linked in high amounts to potential hormonal effects, which is why many parents are understandably cautious about BPA exposure in food containers, baby bottles, and dental materials.
Some studies have found that trace amounts of BPA can be present in certain types of dental sealants, typically as a byproduct of the manufacturing process. However, it’s important to understand the context and actual risk level involved.
Are Dental Sealants Safe?
Yes — according to major dental and health organizations, dental sealants are safe when applied correctly by a trained dental professional.
The American Dental Association (ADA) and the U.S. Centers for Disease Control and Prevention (CDC) both recommend dental sealants as a proven and safe method to prevent cavities in children and adolescents.
Research shows that if any BPA is present in a sealant, it is typically at extremely low levels — far below the threshold known to cause harm. In fact, studies indicate that children are exposed to more BPA through everyday sources like household dust, canned foods, and receipts than from dental materials.
How Long Does BPA Stay in the Mouth?
Even when trace BPA is detected in certain sealants, the exposure is temporary. Research shows that BPA may be measurable in the saliva for only a few hours after application — after which it quickly dissipates.
Dentists can also minimize even this brief exposure by wiping and rinsing the tooth surface after sealant placement. This simple step removes any unpolymerized material that could contain BPA, reducing the already minimal risk to virtually zero.
At North Shore Dental Center, our team takes every possible precaution to ensure your child’s safety. We use high-quality, trusted materials that meet all health and safety standards.
The Real Benefits of Dental Sealants
While it’s natural to be cautious about any dental material, it’s equally important to consider the proven benefits of sealants. Untreated cavities can lead to pain, infection, difficulty eating, and missed school days — not to mention higher treatment costs later on.
Dental sealants provide:
- Powerful cavity prevention: They block bacteria and food particles from entering deep grooves.
- Pain-free application: The process is quick, comfortable, and requires no drilling or anesthesia.
- Long-lasting protection: Sealants can last up to 10 years with regular dental checkups.
- Support for better oral hygiene: Smooth tooth surfaces are easier for children to clean effectively.
The benefits of protecting your child’s teeth far outweigh the minimal and temporary risk of BPA exposure.
What to Ask Your Dentist About Sealants
If you have concerns about BPA or any dental material, talk openly with your dentist. At North Shore Dental Center, we welcome your questions and will explain every step of your child’s care in detail.
You can ask your dentist:
- What type of sealant material do you use?
- Does it contain any BPA or related compounds?
- How do you minimize BPA exposure during application?
Many dental offices, including ours, use BPA-free sealant materials whenever possible. When combined with proper placement and aftercare, the treatment is both safe and effective for children of all ages.
How Sealants Are Applied
The application process for sealants is simple and noninvasive:
- Cleaning: The tooth is cleaned and dried.
- Preparation: A mild solution is applied to help the sealant bond properly.
- Rinsing and drying: The tooth is rinsed and dried again.
- Sealant application: The liquid sealant is painted onto the tooth and hardened using a special light.
The entire process usually takes only a few minutes per tooth and provides years of protection.
Maintaining Sealants Over Time
Sealants do not replace regular brushing, flossing, or dental checkups, but they add an extra layer of defence. During each visit, your dentist will check to make sure the sealants are intact and reapply them if needed.
Regular preventive care, including sealants, fluoride treatments, and routine cleanings, helps children maintain healthy teeth and avoid cavities before they start.
