Biological Dentistry

Biological dentistry, also referred to as holistic dentistry, is an alternative to traditional dentistry, focusing on the patient’s overall health and nutrition. These particular dentists believe in a holistic approach, meaning that they take into account the entire body of the patient, not just the diseased area. Practitioners of biological dentistry believe the compounds contained in an amalgam filling are toxic to the human body. An amalgam filling is 50 percent mercury and does include other heavy metals such as copper. It is their belief that this toxicity causes or contributes to disease in the body, including cancer. Dr. Josef Issels was one of the first to connect dental procedures, such as amalgam fillings and root canals, to poor patient health. He believed decayed teeth should be completely removed allowing the body to rid itself of the toxins and their effects.


Treatment by a holistic dentist often involves removing amalgam fillings and replacing them with a synthetic substitute. Biological dentists also claim that decaying teeth produce a toxic substance known as dimethyl sulfide. Their belief is that this substance may lead to various cancers such as mesothelioma. Cavitational osteopathosis is the term given to cavities in the jaw that are undetected by an x-ray but believed to be present by a biological dentist. Along with this dental work, a biological dentist may suggest a nutrition plan, including an element for detoxification. Oral acupuncture and a realignment of the jaw may be undertaken. Chelation therapy, a treatment for heavy metal poisoning, may be recommended, although there is no supporting evidence of these conclusions. Neural therapy, laser therapy, and mouth balancing are other controversial treatments offered by biological dentistry practitioners.

Lack of Endorsement

These forms of treatment are currently not supported by the American Cancer Society, and the American Dental Association has declared the practices of biological dentistry unethical. Furthermore, relying on biological dentistry, or any alternative treatment, in lieu of standard treatments, or as the sole treatment for cancer and other illnesses, is not recommended. However, there is a small segment of the population who are allergic to certain metals and for these few, replacing amalgam fillings may relieve painful mouth sores. The ADA, the National Institute of Health, and the U.S. Food and Drug Administration all maintain their stance that the use of amalgam fillings remains safe.

Although currently not endorsed by research or the ACS, alternative treatments such as biological dentistry, are used by some regardless of their reported effectiveness. Patients diagnosed with mesothelioma and other cancers might consider these types of alternative treatments in conjunction with standard methods.
