I'm reading up on the suggestion that patients with the gum condition Periodontitis is linked to Hashimoto's patients. Is anyone else aware and researched further? Oil pulling is suggested. There is also mention of the antibiotic doxycycline that is used for periodontitis, which says interestingly this same antibiotic has been reported to eliminate TPO antibodies for some and may be an option to consider in someone with both Hashimoto's and periodontitis. Any thoughts anyone?
