Oral health may be a critical but often overlooked factor in managing Lyme disease and other tick-borne illnesses, according to a recent clinical lecture by Dr. Alexander Volchonok, a board-certified periodontist with expertise in biologic dentistry. He presented alongside Dr. Susan Marra, a physician who treats complex chronic conditions including Lyme disease and co-infections.
The experts emphasized that oral health extends beyond teeth and gums. The mouth interacts with the immune system, influences inflammation, and sends systemic signals that can affect overall health. In some patients with tick-borne illnesses, unresolved oral inflammation may contribute to persistent immune activation and hinder recovery, even when appropriate antimicrobial therapy is administered.
“The mouth is a gateway between the outside world and the immune system,” Dr. Volchonok explained. “Microbes, nutrients, and inflammatory signals from the oral cavity can influence immune activity throughout the body.”
A healthy oral microbiome—composed of bacteria, fungi, and viruses—supports digestion, blood flow, and immune regulation. But when the microbiome becomes imbalanced, a condition known as dysbiosis, harmful bacteria proliferate, inflammation increases, and the immune system remains chronically activated.
Patients with Lyme disease are particularly vulnerable due to immune dysregulation, medication effects, stress, nutrient deficiencies, and reduced saliva flow. Dysbiosis and chronic oral inflammation may become self-sustaining, increasing the body’s overall inflammatory load.
Periodontal disease, a bacterial infection affecting the tissues around the teeth, was highlighted as a major driver of systemic inflammation. Often painless in early stages, periodontal disease creates a persistent inflammatory wound with direct access to the bloodstream, potentially compounding symptoms in patients with impaired immune regulation.
The lecture also discussed less obvious dental and jawbone issues, such as necrotic teeth and poorly healing jawbone after extractions or dental trauma. These silent conditions may continue to stress the immune system without producing noticeable symptoms.
Antibiotic therapy alone may not fully address these oral issues. Low-oxygen pockets, biofilm formation, and reduced blood flow in diseased oral tissues can limit the effectiveness of systemic treatments. Addressing oral health may therefore be a crucial adjunct in the comprehensive care of Lyme disease patients.
Experts stressed that oral disease does not cause Lyme disease. Instead, it can act as an additional source of inflammatory stress that slows recovery. Integrating oral evaluations into Lyme care may help identify hidden contributors to ongoing illness and support more effective treatment strategies.
