A client sits down and runs through four years of symptoms. Fatigue that no amount of sleep touches. Joint aches that move around. Brain fog. Swollen glands on one side that never quite go down. They've had the full workup. Labs, imaging, specialists, a few diagnoses that didn't stick. Somewhere around minute fifteen I'll ask what work they've had done on their teeth, and there's always a pause, because nobody has asked them that before.
I'm not saying the mouth is the answer every time. It isn't. But it sits right next to the brain, it's full of blood supply and lymphatic drainage, and it is the one region of the body that most medical workups skip entirely. Your dentist looks at your teeth. Your doctor looks at everything but. The jaw falls into the gap.
What People Are Actually Asking
The questions I get are pretty consistent. Can an old root canal make me sick? Should I have mine pulled? What is a cavitation? My tooth doesn't hurt, so does that mean it's fine? My biological dentist says there's an infection in my jawbone and my regular dentist says there's nothing there, so who do I believe?
That last one deserves a straight answer rather than a dodge, so let me lay out where the field actually stands before I give you my read.
The History Nobody Explains
In the early 1900s there was a widely held idea called focal infection theory: that a local infection, often in a tooth, could seed disease elsewhere in the body. Weston Price did a lot of the writing that popularized it in the 1920s. Teeth came out by the thousand on that reasoning. Studies in the 1930s are generally credited with discrediting the theory, and the profession moved on hard in the opposite direction.
Today the mainstream endodontic position is clear: there is no good evidence linking properly performed root canal treatment to disease elsewhere in the body, and recent work found no change in cancer risk. The American Association of Endodontists says this directly. Modern treatment removes the infected tissue, disinfects the canal system and seals the tooth.
I'm telling you their position in their words because you deserve to know what the other side of the table says before you hear mine. Anyone who presents this as settled in their favor, in either direction, is overselling.
Where I Actually Land
Here's my clinical read, and I'll own it as mine.
An untreated infection in a tooth is not controversial at all. Everyone agrees that bacteria reaching the pulp can spread to the root, form an abscess, damage the supporting bone, move into nearby tissues of the head and neck, and in rare cases become systemic. That is standard medicine. So the question was never whether a tooth can make you sick. It's whether a treated tooth can still be a problem.
A root canal does not sterilize a tooth. It cleans and seals the main canal. A tooth's internal structure includes thousands of tiny tubules that no instrument reaches. In a person with a well-functioning immune system, that is usually a non-issue, and most root canals go on to cause nobody any trouble for decades. In a person already carrying mold exposure, a tick-borne infection, heavy metal burden, or a mast cell system that's been running hot for years, I treat a chronically inflamed area in the jaw as one more thing on an already overloaded pile. Not the cause. A contributor.
The same logic applies to what people call cavitations: an area in the jawbone, often at an old extraction site like a wisdom tooth, that didn't fill in with healthy bone. I want to be honest that this one is genuinely contested. The FDA declined to clear a device for diagnosing these lesions as claimed. The ADA has not endorsed the diagnosis. The AAE has said it cannot support surgical intervention for a suspected lesion without a confirmed diagnosis, and warns the surgery can make pain worse. A published systematic review found observational studies only, no randomized trials, and poor overall quality, with no established prevalence in the general population.
I still look. I look because the clients in front of me have exhausted everything else, because most of these areas are painless so symptoms won't find them, and because a 3D cone beam scan is a low-risk way to get a picture. What I do not do is send someone straight to surgery on a hunch. The downside of an unnecessary jaw surgery is real and permanent.
What This Looks Like in Real Life
The pattern that makes me look: a person who got meaningfully worse at a specific point in time, and when we build the timeline, that point sits near a dental procedure. An extraction, a root canal, a crown. Often one-sided symptoms. Swelling, aching, or nerve sensations on the same side as the work. A gland that stays up. Sometimes facial pain with no neurological explanation.
The other pattern: someone who has done everything right on mold, gut and infections, got eighty percent better, and then stalled for a year with no further progress. That last stubborn twenty percent is where I start asking about the mouth.
What I Recommend
- Build the timeline first. Write down when your symptoms meaningfully changed and what else happened within a few months of it. Dental work included.
- Get a 3D cone beam scan rather than a standard flat X-ray if the question is the jawbone. A flat image can miss a great deal.
- Get two reads on the images. One from a dentist who works in this area and one from someone who does not. If they agree, you have your answer. If they disagree, you've learned how ambiguous the finding is, which is worth knowing before anyone picks up a drill.
- Treat the rest of the load first. If mold, infections and gut function are still unaddressed, fix those before you take out a tooth. Plenty of people who were sure it was the tooth got better without touching it.
- Do not extract a tooth as an experiment. You cannot put it back. The bar for surgery should be a clear finding plus symptoms that match it, not a theory plus frustration.
I take the mouth seriously because it is a genuine blind spot in standard care, and because I've watched clients stall for years in that blind spot. I also take it seriously enough not to send anyone into irreversible surgery on the strength of a hunch. Both of those things are the same position, not opposite ones.
If you've worked the list and you're still stuck, it may be worth looking at a region nobody has checked yet.
Has anyone ever connected a dental procedure to a change in how you felt? Tell me what happened and when, because the timeline is usually where the answer hides.
