Anita has spent decades studying one of the most controversial subjects in dentistry: mercury. Long before most people were willing to question it, she was asking why a neurotoxin was still being used in dental materials and what that mighty mean for the rest of the body. What struck me about Anita is her persistence. She has followed this issue through science, policy, and global health debates, working alongside researchers, dentists, and activists who believe the mouth may play a much larger role in systemic illness than we currently acknowledge. In this episode, Anita breaks down the history of mercury amalgam fillings and why they remain so widely used. We talk about how toxic metals interact with the nervous system, immune system, and cellular metabolism — and why biological dentistry is beginning to gain attention among practitioners who are looking deeper for the roots of chronic illness. This conversation is about awareness, responsibility, and the courage to question long-standing systems when the health of the body may be at stake. This conversation is intense.
