Why Your Cardiologist and Dentist Need to Coordinate Care

Thirty years ago, when I began linking periodontal disease to cardiovascular risk, many colleagues thought I was overreaching.

“Stay in your lane,” they told me.

I kept noticing the same pattern.

Patients with gum disease frequently also had high blood pressure, atrial fibrillation, valve problems—or worse.

Decades of clinical observation have since been supported by research.

A 2024 umbrella review by Arbildo-Vega et al. analyzed 41 systematic reviews and concluded that periodontal disease increases cardiovascular risk.

Even more compelling, a 2024 meta-analysis by Meng et al. found that treating gum disease reduces CRP and IL-6, two central inflammatory markers linked to heart risk.

This inflammation is reversible, and your cardiologist may be measuring elevated markers in your blood without recognizing the mouth as a source.

Heart disease claims an American life every 33 seconds and remains the leading cause of death in the United States.

To help bridge the gap between dental and medical care, I created the Physician–Dentist CRP Letter.

It’s free and thousands of patients have used it to connect their care teams, helping clinicians catch inflammation that might otherwise be missed.

If you want to actively lower inflammation, you need a plan that addresses the root cause in the mouth.

Over the years I refined the Mouth–Heart Protocol, a straightforward, evidence-informed framework designed to support oral and cardiovascular health. This is the approach I used in my Silicon Valley practice to help patients control inflammation and protect their hearts.

This is educational content and not medical advice. Discuss any changes with your healthcare team.

The Mouth–Heart Protocol

These steps help control inflammation at its source—the mouth—and support cardiovascular health. Consult your dentist and physician before making changes.

1. Get a High-Sensitivity CRP Test
Ask your physician for a high-sensitivity CRP. Values above 1.0 mg/L often indicate hidden inflammation, which can include periodontal disease.

2. Use the Physician–Dentist CRP Letter
Provide one copy to your doctor and one to your dentist so they can coordinate care and interpret CRP in context. Many physicians don’t realize oral inflammation can raise CRP.

3. Switch to 3–4 Month Cleanings
Quarterly professional cleanings help prevent recurring gum inflammation and reduce systemic inflammatory burden.

4. Find a Dentist Who Treats Whole-Body Health
Select a provider who understands oral-systemic connections and how oral inflammation affects cardiovascular and metabolic health.

5. Optimize Your Airway
If you snore, wake unrefreshed, or have difficult-to-control blood pressure, consider an airway/sleep evaluation. Sleep apnea worsens cardiovascular inflammation.

6. Check Existing Root Canals
Failed or chronically infected root canals can drive systemic inflammation. Have them evaluated periodically, ideally using 3D imaging when appropriate.

7. Rebuild Your Oral Microbiome
Support beneficial oral bacteria that protect gums and vascular health:

Drink green tea regularly for catechins that help reduce harmful bacteria and support vascular function.
Consider a prebiotic toothpaste with nano-hydroxyapatite to support enamel and a balanced oral microbiome.
Chew xylitol gum after meals to reduce harmful bacteria and support saliva flow.
Use a tongue scraper daily to remove biofilm from the back of the tongue where harmful microbes accumulate.
Avoid routine use of antiseptic mouthwashes, which can disrupt beneficial oral bacteria.

8. Support Inflammation Control with Nutrition
Key nutrients support gum and cardiovascular health:

CoQ10 – supports gum tissue energy and mitochondrial function.
Magnesium – helps maintain vascular tone and modulate inflammation.
Vitamin D3 + K2 – supports calcium balance for bones, teeth, and arteries.

Both your dentist and physician should monitor oral inflammation with the same diligence they apply to cholesterol and other cardiovascular risk factors.

You deserve coordinated, integrated care.
