Ulcers, caused by H. pylori, can originate from an infected tooth or root canal treated tooth. This is what I think happened to my wife, she had an ulcer, and she had an infected tooth, which still showed a shadow in her digital x-ray. When I googled on ulcer & root canal the following medical article popped up:
Helicobacter pylori and its reservoirs: A correlation with the gastric infection
This is a review paper on the correlation between ulcers and infected teeth. The infection can serve as a 'reservoir' for H. pylori, the ulcer is treated and then comes back, because the underlying tooth infection is not being treated. I use chlorine dioxide, I rinse my mouth with four activated MMS drops and swallow it. Bacteria from the teeth or infected gums can cause heart disease and arthritis.
I attached the slice from a 3-D scan of my wife's molar, you see a dark spot above the white root canal filling.
Thanks, that's so interesting!
Oral infections are just as pernicious and intestinal ones. It's fascinating how systemic their effects can be.
Due to some circumstances, I haven't been to the dentist in 3 years. I don't miss the x-rays, but I've had health problems in the meantime which may be driven by oral issues.
