Hal Huggins
Hal Alan Huggins (1937 – November 29, 2014) was an American alternative dentistry advocate and campaigner against the use of dental amalgam fillings and other dental therapies that he believed to be unsafe. Huggins began to promote his ideas in the 1970s and played a major role in generating controversy over the use of amalgam. Huggins's license to practice dentistry was revoked in 1996 after a panel found him guilty of gross negligence. Since then, he continued to publish on the topic of mercury and human health and believed that dental amalgam and other dental practices were responsible for a range of serious diseases. Many of Huggins' health claims have been criticized as pseudoscientific and quackery. Life and career Huggins received his DDS in 1962 from the University of Nebraska at Lincoln. In 1973, he became involved in the study and research of mercury toxicity and its impact on human health. Through the course of these investigations, Huggins earned an MS from the University of Colorado at Colorado Springs in 1989 with special emphasis in toxicology and immunology. Huggins subsequently became a prolific campaigner against the use of amalgam dental fillings, creating the Huggins Diagnostic Center in Colorado Springs, Colorado.
