There is no evidence to support the claim that mercury from dental
fillings can make MS symptoms worse. Any reduction of MS
symptoms after removal of mercury amalgam fillings is most likely a coincidence.
It likely occurs because the person has entered a period of remission that is not related to
the dental treatment. The
placebo response in people who have MS may be as high
as 70%. This makes it very hard to know that treatment caused an
improvement in symptoms.
Some alternative medicine practitioners say that vapour that escapes
from the mercury in dental fillings can lead to changes in blood composition. They think that this may contribute to
multiple sclerosis (MS) symptoms. They claim that
removing the fillings can benefit people who have MS.
Treatment involves removing mercury amalgam fillings. The person is tested for the
best replacement filling material. Then that material is used to replace the mercury
fillings. The person also gets detoxification therapy. This may include nutritional support to
balance body chemistry. It may also include the use of compounds to remove mercury from the body
(chelating agents), vitamin C supplements, and psychological counselling.
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.
