In his work, Dr. Tomasian applies an understanding of bio-meridians, cavitations (occult oral infections), and bio-toxicity. He acknowledges that just as systemic problems can degrade oral health, poor oral health can be the source of systemic problems. Dr. Tomasian helps his clients appreciate biological function beyond the context of the mouth, and supports them in making informed choices about health care. He also acknowledges the prevalence of metal (especially mercury) toxicity, and has not used amalgam for many years.
