Your dentist has recommended dental sealants for your child. You want to protect their teeth from cavities. But then you read that some sealants contain BPA — a chemical you are trying to avoid. Do dental sealants pose a real BPA exposure risk?
Dental sealants are a thin coating painted onto the chewing surfaces of back teeth. They fill in the grooves where food and bacteria get trapped. Sealants are highly effective at preventing cavities, especially in children and teenagers.
Do sealants contain BPA?
Some older dental sealants did contain BPA. However, most modern dental sealants are BPA-free. The concern comes from a specific type of resin that can release very small amounts of BPA when it cures.
The good news is that BPA-free alternatives are now standard in most UK dental practices. These alternatives use different resin chemistries that do not produce BPA.
How much BPA could your child be exposed to?
Research shows that any BPA release from dental sealants is extremely low and short-lived. Studies have detected BPA in saliva for a few hours after sealant placement. But the levels are much lower than what would cause any health concern.
The amount is comparable to what you might absorb from handling a receipt or eating canned food. It is not considered clinically significant.
The benefits outweigh the risks
Dental sealants prevent up to 80% of cavities in the back teeth where most cavities form. They are a proven, safe, and cost-effective way to protect your child's teeth.
The small potential BPA exposure from some sealants is far less concerning than the real risk of untreated cavities. Cavities lead to pain, infections, and costly dental work.
What you can do
Ask your dentist about the specific sealant they use. Most will use BPA-free materials and can confirm this for you. If you have concerns, your dentist can recommend BPA-free options.
The most important thing is to get sealants placed when recommended. The protection they provide far outweighs any theoretical risks from trace chemical exposure.
