Why Your Dentist Is Wrong About Toothpaste, Flossing, and Fluoride with Dr. Al Danenberg

Periodontist Dr. Al Danenberg was diagnosed with incurable bone marrow cancer (multiple myeloma) in September 2018 and given 3 to 6 months to live. His oncologist wanted to start chemotherapy the next day, but Dr. Al rejected chemo and instead focused on natural methods to help his body heal. While Dr. Danenberg has since passed on, he survived most of his remaining years with an outstanding quality of life, shocking his oncologist and maintaining such good health that his gut microbiome diversity was in the 97th percentile. In this episode, filmed in March 2023, Dr. Al discusses his diagnosis and why he believed his cancer stemmed from toxic exposures in dental school in the late 1960s and early 1970s. He emphasizes that all cancers are diseases of lifestyle, and that there are very few wild animals with cancer and very few primal societies with gum disease, tooth decay, chronic diseases, or cancer. Dr. Al also explores a few somewhat shocking oral health ideas, including why dental plaque is actually healthy! He backs this surprising claim with three critical roles plaque plays in the mouth: it acts as a gatekeeper, allowing minerals from saliva to remineralize teeth; it contains chemical buffers that keep pH at ~5.5 to prevent decay; and it produces hydrogen peroxide that kills pathogenic bacteria trying to invade. I know you'll enjoy this episode with the late Dr. Al Danenberg.
