Biological Fillings
Concerned About BPA in Dental Fillings? What You Should Know – Costa Rica BioHealth
Some people worry about mercury in amalgam fillings, while others raise concerns about BPA (bisphenol A) in tooth-colored composite fillings. And they’re right to ask questions. Many composite resins contain BPA or related compounds, which are known endocrine disruptors.
A recent study found that over 86% of the 130 composite products examined were based on BPA derivatives. Only 18 were completely free of these compounds. This is particularly concerning since composites aren’t just used for fillings but also for sealants, which are often recommended for children. Research has linked BPA exposure to potential developmental effects on the brain and reproductive system, as well as increased risks of obesity, diabetes, heart disease, infertility, thyroid dysfunction, and certain cancers.
How Big of a Risk Is BPA Exposure?
The body can generally excrete BPA efficiently under normal circumstances. However, with constant exposure from multiple sources—including plastics, food packaging, and even dental materials—accumulation is possible. Studies show that over 90% of people have detectable levels of BPA in their system.
Minimizing exposure, especially in dental work, is a smart approach. Fortunately, there are BPA-free alternatives. At Costa Rica BioHealth, we prioritize the safest alternatives available on the market.
Other materials are labeled as free from easily released or ionizable BPA:
• Admira
• Clearfil
• Concise
• Esthet-X-HD
• Filtek Supreme
• Filtek Supreme XT
• Filtek Z-250
• Grandio SO
• Herculite XR
• Kalore
• Point 4
• Premise Indirect
• Vertise Flow
• Z-100
While some of these products may contain derivatives like bis-GMA or bis-DMA, the BPA release from these compounds is considered negligible.
BPA-Free Dentistry at Costa Rica BioHealth
At Costa Rica BioHealth, we prioritize biocompatible materials and use only BPA-free and fluoride-free composites. (Yes, some composites contain fluoride as well.) For patients with chemical sensitivities or chronic illnesses, additional biocompatibility testing can be done to determine the safest material for their specific needs.
For those seeking a completely metal-free and highly biocompatible option, ceramic restorations—such as inlays, onlays, and crowns—are another excellent alternative.
What If You Already Have BPA-Containing Fillings?
Unlike mercury amalgam fillings, there’s little benefit in removing BPA-containing composites or sealants once they’re placed. Studies show that most BPA exposure happens at the time of placement, with levels dropping significantly within days. A recent study found that BPA levels in saliva were near zero within a week of placement.
The best course of action? Simply choose BPA-free materials for any future dental work to further reduce your exposure.
At Costa Rica BioHealth, we believe in biocompatible, non-toxic dentistry for optimal long-term health. If you have questions about safe dental materials, we’re here to help!
