Multiple Sclerosis: Mercury Dental Fillings

Topic Overview

There is no evidence to support the claim that mercury from dental fillings is a factor in making MS symptoms worse. Any reduction of MS symptoms after removal of mercury amalgam fillings is most likely a coincidence and occurs because the person has entered a period of remission unrelated to the dental treatment. The placebo response in people who have MS may be as high as 70%, making it very hard to know that treatment is responsible for an improvement in symptoms.

Some alternative medicine practitioners maintain that vapour escaping from the mercury in dental fillings can lead to changes in blood composition, possibly contributing to multiple sclerosis (MS) symptoms. They claim that removing the fillings can benefit people who have MS.

Treatment involves removing mercury amalgam fillings, testing for the optimum replacement filling material before substituting it for the mercury fillings, and detoxification therapy. This may include nutritional support to balance body chemistry, use of compounds to remove mercury from the body (chelating agents), vitamin C supplements, and psychological counselling.

Warning

Clinical research has been unable to show that removal of mercury fillings (dental amalgams) has any benefits for people with MS. It is not recommended by most experts.
