What Is Your Oral Health Doing to Your Inflammation Levels?
*This post is based on a recent podcast conversation with Dr. Kelly Blodgett, a biological dentist based in Portland, Oregon.*

One of the most common questions I hear from patients working through a chronic inflammatory process is some version of: "What else should I be looking at?" They are changing their diet. They are sleeping better. They are reducing their toxic exposures. They are doing the work. And yet something persists.
In a significant number of those cases, the answer is in their mouth.
I recently had the pleasure of sitting down with Dr. Kelly Blodgett, a biological dentist in Portland, Oregon, who has spent his career thinking carefully about how dental health connects to systemic health. We had dinner together in Austin before recording, and the conversation that followed covered territory that I think will be directly useful for anyone navigating chronic inflammation, preparing for surgery, or managing a condition with an immune component.
The connection between the oral cavity and the rest of the body is not theoretical. It is clinical. And it is underappreciated.

## The Mouth as the Beginning of the System
The oral cavity is the beginning of the GI tract. That is not a metaphor. It is anatomy. What happens there, in terms of microbial load, inflammatory activity, and tissue integrity, does not stay there. The lymphatic drainage and blood supply that feed your mouth feed the same systems that feed every other organ and implanted device in your body.
I was reminded of this early in my surgical training, working alongside cardiac surgeons. Before any heart valve surgery or cardiac procedure, patients were required to have a dental clearance. If there was active gum disease or any oral infection, the procedure was deferred. The reason is direct: dental procedures can introduce bacteria into the bloodstream, and if those bacteria coat a heart valve or cardiac implant, you can develop endocarditis. The medical community has known this for decades.
Antibiotics are given prophylactically before dental appointments for patients with certain cardiac conditions and joint replacements for exactly this reason. What Dr. Blodgett and I discussed at length is why the same logical concern is not routinely applied to other implanted devices, including breast implants.

## Gum Disease: The Visible Starting Point
The most visible marker of oral inflammation is gum disease. If your gums bleed when you floss or brush, there is an active inflammatory process in your mouth. Dr. Blodgett notes that the dental community and the medical community agree on this. Bleeding gums are a problem, and they signal that the immune system is already engaged in that tissue.
For patients carrying a broader inflammatory burden, this is not a minor issue. It is an ongoing driver. A chronically inflamed periodontal environment introduces a steady stream of bacterial signaling into the bloodstream, activating immune responses that compound whatever is already present systemically.
Addressing gum inflammation is the starting point. It is the most recognizable, the most documented, and the one with the clearest consensus across specialties. If you have gum disease, that is step one.

## Root Canals: What the Research Is Showing
The topic that surprised me most when Dr. Blodgett and I began comparing notes is root canals.
A root canal removes the blood supply from a tooth. The tooth becomes, as Dr. Blodgett describes it, a dead organ connected to living bone and gum tissue. Because of the porosity of the dentin surface of the tooth, it is structurally capable of absorbing microbes the way a dry sponge absorbs water. Without a blood supply to provide immune surveillance, those microbes have no mechanism to be cleared.
Dr. Blodgett has been sending extracted root-canaled teeth to a DNA laboratory in Colorado for approximately seven years. The lab uses PCR testing, which identifies DNA fragments from bacteria, viruses, parasites, and fungi. Every single root he has sent, now more than 500 samples, has come back positive for some mixture of microbial contamination inside the root system itself.
This finding has a direct parallel in my own work. My research team has published a series of 900 consecutive implant capsule samples using the same PCR methodology. We found that approximately 30 to 34 percent of those samples contained biofilm: organized colonies of bacteria, fungi, or mycobacteria embedded in the capsule tissue, undetectable by standard culture methods. The bacterial DNA was there. Standard testing would have missed it.
What Dr. Blodgett describes in root canals maps onto the same phenomenon. Standard X-rays show bone loss or periapical abscess when the infection has progressed to that stage. They cannot show microbial colonization within the root structure itself. PCR can. And when you use PCR, the picture is consistent: the roots are loaded.
This does not mean every person with a root canal is acutely ill, or that removing root canals will resolve every chronic health condition. What it means is that for patients carrying unexplained inflammatory burden, particularly those who report that something feels wrong even when imaging looks normal, the presence of a root-canaled tooth is worth a careful, informed conversation with a knowledgeable provider.

## Biofilm, Implants, and the Oral Connection
For patients in my practice, particularly those evaluating implant-associated health concerns, the biofilm conversation is familiar. We know from our published research that biofilm can be present in implant capsules even when clinical and radiographic evaluation looks unremarkable. The immune response to biofilm is real, measurable, and persistent.
What Dr. Blodgett's work adds is the understanding that biofilm is not only a consideration around implanted devices. It is a consideration inside root-canaled teeth, which are themselves in direct contact with the vascular and lymphatic systems that supply the rest of the body.
Breast implants, as I often explain to patients, have surface area that matters. A smooth implant has less surface area and less surface complexity than a textured implant. More surface complexity means more potential contact with tissue, more opportunity for immune activation, more surface for biofilm to form. The same principle applies to any foreign or non-vital structure inside the body.
A root-canaled tooth is a non-vital structure with a porous surface embedded in living tissue with direct vascular access. The biology is not fundamentally different from other biofilm scenarios. The immune system responds to what it perceives as a threat, and that response does not stay local.

## Dissimilar Metals and Galvanic Effects
Dr. Blodgett raised a topic I had not thought deeply about: the electrical environment inside the mouth when multiple different metal restorations are present.
Saliva is an electrolyte solution. When you place dissimilar metals in that environment, the same electrochemical principles that operate in a battery begin to operate in the mouth. Different metals with different electrical potentials, sitting in a conductive solution, generate small electrical currents. This galvanic effect can shift the local electrochemical environment in ways that may alter how microbes behave and how certain teeth are more prone to breakdown than others.
The dental profession, Dr. Blodgett notes, has historically placed materials without asking two basic questions: what is the energetic effect of this combination, and might this person be sensitive to any of the components of the alloy? For most people, this is not clinically significant. For those with underlying immune reactivity or sensitivity, it may contribute to unexplained oral and systemic symptoms.

## Biocompatibility Testing: Choosing Materials That Work for You
One of the most practical takeaways from our conversation is the existence of a blood-based biocompatibility test for dental materials. Dr. Blodgett explained that a blood draw is sent to a laboratory, the serum is tested against the full range of dental materials currently on the market, and the results identify which products are least reactive, moderately reactive, or most reactive for that individual.
For most people, this test costs around $400. The test database has expanded dramatically in recent years and now covers a much wider range of materials than it did five years ago. For the majority of patients, most materials test as least reactive. But for the one to two percent who have specific immune reactivity to a given material or alloy, this test provides actionable information that changes what gets placed in their mouth.
For patients who are already managing an inflammatory condition, for patients with a known sensitivity or immune issue, or for patients who are choosing dental work carefully as part of a broader health optimization effort, this test is a logical step before any significant dental procedure.

## The Oral Microbiome, Diet, and the Gut Connection
What you eat directly affects your oral microbiome, and your oral microbiome affects your gut microbiome. The connection runs in both directions, and both affect systemic inflammatory burden.
Dr. Blodgett and I discussed several specific patterns that are common in the general population and that have meaningful oral health consequences. Acidic beverages consumed throughout the day, including kombucha, despite its health reputation, and the Starbucks drink category that most of us can visualize, create persistent low-pH exposure in the mouth. The frequency of exposure matters more than any single exposure. Sipping an acidic drink over six to eight hours creates far more erosion risk than consuming the same drink in a short window.
Sugar, particularly fructose from processed foods and fruit juices, feeds bacterial populations in the mouth and gut. It is also highly addictive in a neurochemical sense, which makes it difficult to reduce even when patients understand the consequences. The standard American breakfast, a bowl of sweetened cereal with a large glass of orange juice, delivers a substantial fructose load before the day has started.
For patients in my practice preparing for surgery, I use a higher-protein, reduced-processed-food approach. I typically recommend one and a half to two and a half grams of protein per kilogram of body weight daily. I pair that with digestive enzymes, because rapidly increasing protein intake without supporting digestion creates fermentation problems in the gut. Getting these foundations right supports both oral and systemic health and creates a better starting point for any surgical or recovery process.

## Air Filtration: The Overlooked Parallel to Water Filtration
Dr. Blodgett runs air filtration in every room of his dental clinic, a decision that predates the recent attention to indoor air quality and that makes particular sense in a dental environment. Dental procedures generate aerosols. Those aerosols carry whatever is present in the patient's oral cavity, including the microbial populations we have been discussing.
In his office, air filtration is standard practice. When the local news came to ask him about COVID protocols, they found an office that had already been filtering air for years.
I have taken a similar approach. I currently use a Jasper air filtration unit, which I bring to the surgical center when I operate. I have eleven air filters in my office. The parallel to water filtration is direct. Most people would not drink unfiltered water and consider themselves well-served. The idea that the quality of what you breathe should receive less attention is difficult to defend, particularly in environments where aerosol generation is part of the work.
For patients, this translates to a practical recommendation: filtered air at home is an achievable step, particularly in cities or regions with pollen, mold, or industrial pollutants. Austin, where my practice is located, has significant cedar and oak pollen burdens and has historically had mild enough winters that pollen seasons extend almost year-round. Patients who have relocated here from other climates often report that their symptoms worsened without understanding why. Air filtration is part of addressing that.

## How the SHARP Framework Connects to Oral Health
The SHARP Framework, which stands for Strategic Holistic Accelerated Recovery Program, is the structure I use to evaluate patients before surgery and guide them through recovery. Oral health is not peripheral to that framework. It is part of the foundational evaluation.
Before surgery, I want to know about any active oral inflammatory processes. Before cardiac surgery, oral clearance has been standard practice in training for decades. The same logic extends to any patient with an implanted device, with a known immune condition, or with unexplained inflammatory burden. A patient who arrives for explant surgery with active gum disease or one or more root-canaled teeth is carrying microbial load that will affect how the immune system responds to the surgical stress of that procedure.
This does not mean we delay every surgery until every dental concern is resolved. It means we include oral health as part of the comprehensive picture, we have the conversation, and we make decisions with full information.

## Practical Steps You Can Take
The practical priorities that came out of this conversation are worth summarizing:
Get your gum health assessed. If your gums bleed when you brush or floss, that is a signal worth addressing. This is the one area of oral health where there is full consensus across dental and medical specialties.
If you have root-canaled teeth and are managing unexplained inflammation, ask a biologically minded dentist to assess them. The fact that a tooth looks normal on X-ray does not mean it is not a source of microbial load.
If you are considering new dental work, ask about biocompatibility testing. It is a modest investment and it allows your dentist to choose materials with your specific immune chemistry in mind.
Be thoughtful about what you drink and how often. Acidic beverages consumed frequently throughout the day are a consistent source of oral tissue damage. Frequency matters more than individual quantities.
Download the Environmental Working Group's Healthy Living app and check the products you use daily. Many personal care products contain compounds that are absorbed through skin and mucous membranes, and the cumulative exposure adds up to something the body is managing quietly.
If you are preparing for surgery, work with a team that looks at your oral health as part of your preparation, not as a separate domain.
