You've probably never Googled what your fillings are actually made of.
Most people haven't. But mercury amalgam is still one of the most commonly placed filling materials in the United States — and most patients don't find out until they start looking on their own. Same goes for nickel-based crowns and composites containing BPA.
Biocompatible materials — ceramic restorations, zirconia, BPA-free composites — are selected based on how your body receives them. Less inflammation. Less sensitivity. Better healing over time.
Your dentist chooses materials for every filling, crown, and implant. Those choices affect your immune system whether you know about them or not.
Have you ever asked what's in your mouth?
