"Dr. Donald Robbins is a graduate and former instructor from the University of Pennsylvania School of Dental Medicine. He has practiced dentistry over 35 years and developed the â€œGREENâ€ BioSafeDentistryâ„¢ system of practice to protect patients, the dentist and staff from the dangerous chemicals and materials in the typical dental office. He created the www.BioSafeDentistry.com site to help educate the public about these materials, and how they can find a BioSafe Dentist. His book, The Toxic Dental Office â€“ How to Protect Yourself and Your Family, was published to help patients choose a dentist with confidence and guidance. Dr. Robbins conducts research on mercury fillings vapor in the mouth and testified at FDA hearings on neurotoxicity of mercury. He lectures to professionals and audiences about using biocompatible dental materials and how offices can avoid using mercury, other toxic metals, like nickel and tin, and fluoride, which is toxic to the body.
