Toxic Fillings? AKA amalgam (silver) fillings. A great assistant once said "If you cannot throw it in the trash, why would you want it in your mouth?" Mercury is a potent neurotoxin that can cause auto-immune diseases, mental disorders, chronic illnesses, and neurological issues at certain levels in the human body. Silver fillings are indeed considered "safe" by OSHA, however, the decision is up to you. Call Davis Family Dental for additional information about your dental care options!
