When patients ask me what they should be doing to prepare for surgery, the list usually covers nutrition, sleep, reducing inflammatory inputs, and optimizing protein intake. What rarely comes up in those initial conversations, and what I now make a point of asking about directly, is oral health.
I recently sat down with Dr. Kelly Blodgett, a biological dentist in Portland, Oregon, who has spent years investigating how dental health connects to systemic inflammation. Our conversation brought into focus a set of clinical questions that any patient carrying implants, managing a chronic inflammatory condition, or preparing for a procedure should have on their radar.

Why the Mouth Matters to the Rest of the Body
The oral cavity is the beginning of the GI tract. The lymphatic drainage and blood supply that feed the mouth are the same systems that feed every other tissue and implanted material in the body.
This connection has been recognized in cardiac surgery for decades. Before any heart valve or joint replacement procedure, patients require a dental clearance. Active gum disease or oral infection is grounds for deferring surgery because the risk of introducing bacteria into the bloodstream and having them colonize the implant or valve is real. Endocarditis is the consequence when this goes wrong.
Dr. Blodgett made a point I found hard to argue with: the same logic that applies to a knee replacement or a heart valve applies to any implanted device. The biology does not change based on the type of implant.

## Root Canals and Microbial Load
The topic that generated the most substantive comparison between our practices was root canals.
A root canal removes the blood supply from a tooth. Without blood supply, there is no immune surveillance. The dentin surface of the tooth is porous, which means it is capable of absorbing microbes the way a dry sponge absorbs water. Over time, those microbes establish themselves inside the root system, forming organized biofilm colonies that a standard X-ray cannot detect.
Dr. Blodgett has been sending extracted root-canaled teeth to a DNA laboratory using PCR methodology for approximately seven years. PCR looks for the DNA signatures of bacteria, viruses, fungi, and parasites. Every single root he has submitted, now more than 500 samples, has come back positive for some form of microbial contamination inside the root structure. Not around the root. Inside it.
This has a direct parallel to work being done in my own practice. We have published a series of 900 consecutive implant capsule samples tested with PCR methodology. We found that roughly 30 to 34 percent of those samples showed biofilm inside the capsule tissue. Standard culture methods would have missed it entirely. The bacteria and fungi were there. The routine test would have said the sample was clean.
Both findings point to the same clinical conclusion: standard imaging and standard culture methods leave a significant category of microbial burden undetected. For patients with unexplained symptoms, that undetected burden matters.

## The Patient Who Knows Something Is Wrong
One detail from Dr. Blodgett's clinical experience resonated immediately: many of his patients report an intuitive sense that something is wrong with a root-canaled tooth, even when the X-ray looks normal. The objective measures say fine. The patient says otherwise.
I hear the same thing. Patients arrive having been told their imaging is clean, their labs are unremarkable, and there is nothing to explain what they are feeling. In the work I do with implant-associated health concerns, we know that standard testing misses a meaningful portion of what is actually present. The same principle appears to apply to root-canaled teeth.
This is not a reason to approach dental history with alarm. It is a reason to approach it with appropriate curiosity, particularly in patients whose symptoms do not have a clear explanation.

## Biocompatibility Testing for Dental Materials
One of the most practically useful pieces of information from this conversation is the existence of a biocompatibility test for dental materials.
The test requires a blood draw. The serum is tested against the current range of dental products and materials on the market. The results show, for that individual, which materials are least reactive, moderately reactive, or most reactive. For most patients, most materials fall in the least-reactive category. But for a subset of patients, particularly those with immune reactivity or known sensitivities, some materials produce a response that would have gone undetected and unaddressed without the test.
The test currently costs around $400. The material database has expanded significantly in recent years and now covers a much wider range of products than it did five years ago.
For anyone preparing for dental work who is also managing an inflammatory condition, this is a worthwhile conversation to have with a biologically minded dentist. Choosing materials intentionally, based on individual immune chemistry, is a meaningful step that does not require guessing.

## Diet, Frequency, and the Oral Microbiome
What you eat affects your oral microbiome. Your oral microbiome, as the first microbial environment in your GI tract, affects your gut microbiome. And your gut microbiome shapes the systemic inflammatory picture.
Dr. Blodgett noted a pattern worth naming directly: the frequency of acidic beverage consumption matters more than any single exposure. Kombucha, which has a genuine health reputation for its probiotic content, is also a low-concentration acid. Sipping it throughout the day creates sustained low-pH exposure in the mouth that erodes enamel over time. The same applies to coffee drinks, sparkling waters, and sodas consumed in sippable vessels across a full morning.
The practical standard he uses is the one I also use with patients: if you are going to consume something acidic or high-sugar, do it in a defined window, preferably with food, and move through it rather than sipping.
In my own surgical preparation protocols, I move patients to a higher protein intake in the weeks before surgery, typically one and a half to two and a half grams per kilogram of body weight per day. Supporting that with digestive enzymes prevents fermentation issues in the gut from the increased protein load. The Pre and Post-Surgery Essentials collection at drrobssolutions.com/collections/pre-post-surgery-essentials includes products that support this kind of preparation.

## Air Quality: The Parallel That Gets Overlooked
Dr. Blodgett's approach to his clinic extends beyond what goes into patients' mouths. Every room in his dental office has air filtration, a decision that predates recent awareness of indoor air quality and that makes particular clinical sense in a dental context. Dental procedures generate aerosols carrying whatever is present in the patient's oral cavity. Filtering that air protects both patients and the dental team.
When local news contacted him during the pandemic asking how he was managing air quality concerns, they discovered an office that had already been filtering air for years.
I have taken the same approach in my own practice. I use a Jasper air filtration unit that I carry to the surgical center when I operate. My office runs eleven air filters across multiple rooms. The parallel to water filtration is direct: most people would not consider drinking unfiltered water. The idea that what you breathe deserves less attention is difficult to defend, particularly in clinical environments where aerosol generation is part of the work.
For patients at home, filtered air is a practical step, particularly in regions with high pollen, mold, or industrial air quality concerns. For patients in Austin, the cedar and oak pollen loads are significant and, given historically mild winters, tend to run nearly year-round. Patients who have relocated here from other climates often do not connect their worsening symptoms to the air. It is a manageable variable when you know to manage it.

## The SHARP Framework and Oral Health
The SHARP Framework, which stands for Strategic Holistic Accelerated Recovery Program, guides how I evaluate patients before surgery and support their recovery. Oral health is not a separate category in that evaluation. It is part of the foundational picture.
Active gum disease is a contraindication to elective surgery in cardiac contexts. The same principle extends to any patient with an implanted device or a condition with an immune component. Before I operate, I want to understand what is happening in the mouth, not because dental history is the only factor, but because it is one factor that can be evaluated and addressed.
For patients using the SHARP approach as their preparation framework, oral health is one of the upstream questions to ask alongside sleep, nutrition, inflammatory burden, and toxin exposure. These are not separate conversations. They are part of the same one.
