What Does Your Mouth Have to Do With Chronic Inflammation Elsewhere in the Body?
(Based on a recent interview with Dr. Dome Nischwitz discussing biologic dentistry and the mouth-body connection)
---
Dr. Robert Whitfield spends his days evaluating chronic inflammation tied to breast implants. Dr. Dome Nischwitz spends his evaluating chronic inflammation tied to dental work. On a recent episode of the podcast, the two compared notes, and the overlap was hard to ignore.
Dr. Nischwitz is vice president of the International Society for Metal-Free Implantology and co-founder of the DNA Health and Aesthetic Center for Biologic Dentistry in Tübingen, Germany. He has placed more than 5,000 ceramic implants, authored the bestselling book It's All in Your Mouth, and is building what he calls the Biological Global Standard, a set of training criteria meant to give biologic dentistry a consistent definition across the field. His question to patients is simple: what is sitting in your mouth, and what is it doing to the rest of your body?
## The Question Dr. Whitfield Hears Every Week
Dr. Whitfield's patients often ask which area to address first, dental work or breast implants, when both may be part of a broader inflammation picture. He typically defers to the biologic dentist's assessment of priority, since dental sources of inflammation are frequently the more accessible starting point for evaluation.
Dr. Nischwitz agreed, explaining that both fields are working toward the same goal: helping the body return to a more balanced, lower-inflammation state through comprehensive evaluation. Teeth, he noted, sit close to the nervous system, which is part of why he often encourages patients to have the mouth assessed early in a broader health optimization plan. He was careful to add that this isn't a universal rule and depends on each patient's history and findings.
## Root Canals and the Question of Dead Tissue
Much of the conversation centered on root canal-treated teeth. Dr. Nischwitz explained that a root canal procedure removes the nerve, blood supply, and lymphatic tissue from inside a tooth, then fills the empty space so the tooth can continue to function for biting. From a purely mechanical standpoint, it's a long-standing and effective solution.
His concern is what's left behind. Each tooth contains thousands of microscopic tubules, and once the living tissue is gone, those tubules can, in some cases, become a home for bacteria that a healthy immune response might otherwise clear. Dr. Nischwitz described this as a potential source of low-grade inflammation that often doesn't cause pain, which is part of why it can go unnoticed for years.
Dr. Whitfield drew a parallel to his own field. In reconstructive and plastic surgery, leaving infected or non-living tissue in place isn't standard practice; devitalized tissue is typically removed and, where possible, replaced with healthy, vascularized tissue. He noted this reflects the same principle behind his own published research on breast implant capsules, discussed in more depth on his Breast Implant Illness resource hub (https://drrobertwhitfield.com/breast-implant-illness). Dr. Whitfield's PCR research (Whitfield et al., Microorganisms 2024) found bacterial contamination in 29% of tested implant capsules, undetectable by standard culture methods. It is the largest PCR-tested explant capsule series in the world. Patients curious about their own inflammatory markers can also review the inflammation test (https://www.drrobssolutions.com/products/inflammation-test) Dr. Whitfield offers as part of a broader evaluation.
Dr. Nischwitz was clear that he isn't suggesting every root canal needs to be revisited. His framework is built around comprehensive evaluation rather than the simple absence of disease, and he reserves this conversation for patients who have already addressed nutrition and lifestyle fundamentals and are still working through symptoms like brain fog, skin issues, or inflammation that hasn't responded to other interventions.
## Cavitations: A Diagnosis Many Dentists Aren't Trained to Make
Dr. Nischwitz introduced a second concept many patients haven't heard of: cavitations, areas of chronic, low-grade inflammation in the jawbone, often left behind after a tooth extraction that didn't fully heal. He estimated that a large share of wisdom teeth extractions can lead to a cavitation, largely because the surgical site isn't always prepared or supported for optimal bone healing.
Diagnosing a cavitation typically starts with a panoramic X-ray and is confirmed with a three-dimensional cone beam CT scan. Dr. Nischwitz noted that only a small fraction of general dentists own this imaging technology, and fewer still are trained to recognize a cavitation on the scan, since it isn't part of standard dental school curriculum.
The two doctors also discussed how emerging diagnostic support software could eventually assist with radiographic interpretation, particularly for practitioners who haven't built years of pattern-recognition experience from reviewing thousands of scans. Both agreed that any such tool would only be as reliable as the experienced clinicians who help develop it, rather than a shortcut around clinical judgment.
## Metal, Mercury, and What Safe Removal Actually Requires
Amalgam fillings, the dark gray-black fillings many people of a certain generation grew up with, are roughly 50% mercury. Dr. Nischwitz was direct that mercury is a highly reactive element, and that these fillings were the standard of care in much of the world, including parts of Europe, until relatively recently.
He was equally direct that removing them isn't something to approach casually. Simply drilling out an amalgam filling can release a concentrated burst of mercury vapor, and he described seeing patients who felt worse after a poorly managed removal. His clinic's protocol includes breaking the filling into pieces rather than drilling through it, using a rubber dam, high-volume suction, and air filtration, along with nutritional support before and after the procedure. His message to listeners: this is useful information to have, not a reason to panic, and safe removal starts with finding a practitioner trained specifically in this protocol.
## The Airway Connection Dr. Whitfield Didn't Expect
One of the more striking exchanges touched on bite height and airway function. Dr. Nischwitz referenced findings suggesting that losing even a small amount of bite height, often from years of teeth grinding, can be associated with a meaningful reduction in blood flow to and from the brain, along with reduced lymphatic drainage during sleep.
Dr. Whitfield shared his own experience: nineteen years of microsurgery, performed while clenching his jaw under a surgical microscope, contributed to a narrowed airway and undiagnosed obstructive sleep apnea, something his wife noticed well before he did. He now uses an oral appliance to manage it. Dr. Nischwitz noted that sleep apnea is often multifactorial, involving swollen tissue from gum disease, food intolerances, or inflammation tied to dental work, and cautioned that popular tools like mouth taping can worsen symptoms if an underlying airway problem hasn't been evaluated first.
## Preparing the Body Before Reconstructive Work
The conversation also touched on Dr. Whitfield's use of autologous fat transfer in reconstructive procedures. He explained that because heavy metals and other compounds tend to concentrate in fat and connective tissue, he requires a body composition scan and toxicity assessment before considering a patient a candidate, and will delay the procedure for patients with elevated markers. If you're evaluating your own readiness for a procedure like this, our pre and post-surgery essentials collection (https://www.drrobssolutions.com/collections/pre-post-surgery-essentials) is built around supporting exactly this kind of preparation window.
Dr. Nischwitz noted this aligns closely with his own approach: addressing metal-containing dental work before pursuing more intensive support protocols, since residual sources of mercury or other metals in the mouth can complicate that process. Both doctors emphasized that preparation, not urgency, tends to produce the best outcomes.
## Simple Steps Dr. Nischwitz Recommends Starting Today
Toward the end of the conversation, Dr. Nischwitz offered a few accessible starting points for listeners:
Toothpaste: Look for a formula built around hydroxyapatite, the mineral that makes up tooth enamel, rather than fluoride, and free of ingredients like SLS, triclosan, and titanium dioxide.
Oral rinse: Consider oil pulling with coconut oil for five to fifteen minutes rather than a conventional antiseptic mouthwash, which can disrupt the oral microbiome.
Tongue care: A daily copper tongue scraper takes seconds and supports a healthier oral environment.
Flossing: Especially useful for anyone with existing dental work; look for microplastic-free options.
Micronutrients: Vitamin D3, K2, magnesium, zinc, boron, biotin, and methylated B vitamins all play a role in supporting tooth and bone health from within.
## How the SHARP Framework Applies to This Discussion
SHARP, the Strategic Holistic Accelerated Recovery Program developed by Dr. Whitfield, follows the same logic that runs through this entire conversation: evaluate before intervening, address sources of chronic inflammation with a careful and specific protocol, and treat the patient as a connected system rather than a single procedure. Dr. Nischwitz's approach to dental toxicity screening before fat transfer candidacy, and his emphasis on full-body preparation before surgery, mirrors exactly how the SHARP framework guides patients preparing for or recovering from implant-related procedures. Preparation, immune support, and identifying sources of toxicity are central to both approaches, and neither doctor frames this work as a guarantee of a particular outcome, but as a way to give the body its best chance to heal.

## Frequently Asked Questions
What is a cavitation in dentistry?
A cavitation is an area of chronic, low-grade inflammation in the jawbone, often at a site where a tooth was previously extracted and the bone did not fully heal. It typically requires a three-dimensional cone beam CT scan to diagnose.
Is it necessary to have a root canal removed?
Not necessarily. According to Dr. Nischwitz, this is a conversation reserved for patients who have already addressed nutrition and lifestyle basics and are still experiencing unexplained symptoms. Any decision should be made after a full evaluation with a qualified provider.
Are amalgam (mercury) fillings dangerous?
Amalgam fillings are roughly 50% mercury. Removal should only be performed by a practitioner trained in safe removal protocols, since improper removal can release mercury vapor. This is a decision to discuss with a qualified dental provider.
How does bite height affect the brain?
Dr. Nischwitz referenced findings suggesting that a loss of bite height, often from grinding, may be associated with reduced blood flow to and from the brain and reduced nighttime lymphatic drainage. Individual findings should be confirmed through evaluation.
Can biologic dentistry help with breast implant illness symptoms?
Both doctors discussed overlapping principles of chronic inflammation evaluation, but each area requires its own independent clinical assessment. Patients with concerns in both areas should discuss sequencing with their respective providers.
## Patient Perspective Critique
A patient reading this would likely find the parallel between dental sources of inflammation and implant-related inflammation validating, since it reframes an overlooked area (the mouth) as worth investigating alongside more familiar sources of chronic symptoms. She may still wonder how to find a qualified biologic dentist near her, or how to know whether her own root canals or fillings warrant a closer look. The tone throughout is measured and educational rather than alarming, which should help a thoughtful reader feel informed rather than pressured into a decision.
