I had root canal procedure last Friday morning to fix infection in my #4 tooth (2 more mortars needs periodontic work) and 2 days later, my 2 month long anxiety, hot flashes and insomnia disappears automatically, and I am back to myself now. If you have bad tooth/teeth pls have it fix because of such connection is existed ... Google search "tooth infection cause anxiety" for more info.
INFECTION: Infections in the mouth (infected root canal teeth, infections in the jawbone from previously extracted teeth, infections under old fillings, periodontal or gum infections) provide a reservoir of toxic substances, which filter through the lymphatic or drainage system and concentrate within the thyroid gland. The thyroid gland contributes much to the mental health of the patient. Disturbed function can result in depression, anxiety, panic attacks, paranoia, voices in the head and insomnia.
Hope this can help some anxiety people ...
