BPA in Dental Products 

BPA in dental products; are they harmful and are there other options?  Wholistic dentists, like Dr. Abeyta, understand that your Dental Health is absolutely intertwined with your overall body health. 

Here’s what you should know about composite fillings, sealants and the risk of BPA exposure. 

What is a BPA? 

BPA or bisphenol A is an industrial chemical that has been used to make certain plastics and resins since the 1950s.  They are found in polycarbonate plastics and epoxy resins. They can also be used in other products such as dental sealants and composites. 

What are Side Effects of BPA Exposure? 

Studies have linked exposure to: 

  • Reproductive issues 
  • Neurological problems 
  • Childhood Asthma 
  • Type 2 Diabetes 
  • Cardiovascular disease 

And for our children, where sealants are recommended for those who are at high risk of tooth decay, studies have shown a wide variety of problems, including early puberty and metabolic disorders such as obesity.   

Are There Alternatives? 

Yes!  Not all composite resins contain BPA derivatives. There are many holistic alternatives that can be used for patients and their children who prefer to limit BPA exposure. 

Another option are ceramics. They are PBA free, broadly biocompatible, and can be used for crowns and inlays. 

What If You Already Have Fillings or Sealants that Aren’t BPA free?  

Don’t worry, unlike mercury fillings, there’s no reason to replace or remove them. Typically, BPA exposure happens when the fillings or sealants are first positioned and while initial BPA levels may be high, they quickly decrease. In fact, a recent study found that after seven days salivary BPA levels were near zero.  

Fluoride released from composites work very similar to BPA.  The main exposure happens at the time of placement and quickly drops. 

Going forward, choose a dentist who provides holistic dentistry to promote optimal teeth / jaw / head / neck structural relationships.  These relationships are vital to support your body in maintaining a strong immune system and structural health.
