While I do not agree with folks that think dental issues are responsible for all illness, I do believe that they can have an effect. I have zero confidence in mainstream dentistry, and in any field of medicine I think there's a great deal people don't know. But I would change my diet before undergoing oral surgery (for thousands of dollars) to address chronic illnesses.
My understanding is that cavitations are more likely when the area left vacant by a wisdom tooth extraction is not properly cleaned out, and then it heals closed, trapping the gnarly stuff (including the connective tissue that held the tooth in place) inside, and results in porous jaw bone tissue. People often don't have symptoms from this because the immune system seals off the area, which takes work to maintain. (If the dental professional performing the extraction just isn't big on cleaning out the spaces, then it makes sense that all four extraction sites would have cavitations.) With root canals, it's also pretty straightforward, because your body wants to reject pieces of dead tissue (and a root canal-treated tooth is dead, as are the connective tissues that held it in place, attached to the jaw) so again the immune system forms and maintains a barrier around the rotting material, which can include a visible pocket of infection.
Everything I know about
this comes from the documentary Root Cause, one holistic dental practice out to swindle people, and an awesome holistic dental practice. Perhaps there are reputable websites someone can recommend? Obviously mainstream dentists get angry when these things are mentioned, and three functional medicine LLMDs just shrugged and said they didn't know much about
it but would not bother unless I had dental symptoms or had tried everything else.
Which brings me back to my point that diet is likely to help vastly more than dental surgery.
I know in some ways a surgery may seem simpler, though!
