Dr. Chuck Reinertsen spent 40 years connecting dental infections to heart disease, pregnancy complications, and Alzheimer’s. The medical establishment resisted. So, we took his message directly to patients through search. In 8 months, DAP took TDMC from zero search visibility to 640K+ impressions, 96 top-10 rankings, and 38% Share of Voice in oral-systemic health.
The Dental Medical Convergence is a 501(c)(3) nonprofit founded by Dr. Charles Reinertsen, a dentist with over 40 years of clinical experience. Its mission is to educate the general public about the critical connection between oral health and systemic disease. 90% of dental infections cause no pain, yet the bacteria enter the bloodstream and contribute to cardiovascular disease, pregnancy complications, diabetes, Alzheimer's, and more. Most physicians do not examine the mouth, and The Dental Medical Convergence provides this life-saving information directly to patients through its website, book, videos, and educational content.
TDMC had the science but no audience, and engaged Digital Authority Partners to fix that. Starting in October 2025, we built two content clusters around the topics patients actually search for: Pregnancy & Oral Health and Heart Health & Oral Health.
Each cluster paired a landing page with 10-15 blog articles targeting real patient questions like “mouthwash safe during pregnancy” and “broken tooth while pregnant.” We layered in YouTube videos with Dr. Chuck, downloadable PDF guides, a brand messaging framework, and E-E-A-T optimization across the board.
Eight months in: 640K+ impressions across 160+ pages, 38% Share of Voice, and Google’s AI cites TDMC 164 times across every major engine. From nothing.
When DAP started working with TDMC, the organization had a website but zero organic search visibility. Not a single keyword ranked. No content strategy existed. The site generated virtually no organic traffic despite Dr. Reinertsen's 40 years of expertise and his message about the oral-systemic connection.
Dr. Reinertsen had tried the traditional route, educating hospitals and physicians about the oral-systemic connection. Hospitals said they didn't want to "be in the referral business." Physicians said they didn't have time (70%+ work for corporations with 15-minute patient slots). The medical establishment wasn't going to change from the top down.
The oral health space online is dominated by massive health publishers with decades of domain authority and millions of backlinks. A small nonprofit with no search history had to find a way to outrank established players. Not by competing head-to-head, but by owning underserved niches and answering genuine questions.
Even as traffic grew, key pages showed average engagement times under 20 seconds with zero key events. Visitors weren't scrolling, weren't clicking, weren't converting. The content strategy was driving traffic successfully, but the website itself wasn't capturing that interest.
We built structured content clusters around TDMC’s two most important verticals.
Google doesn’t rank new sites for health topics unless it trusts the author. We gave Google every reason to trust Dr. Chuck.
A single blog post only goes so far. We built a system where every format feeds the others.
Ranking is one thing. Showing up multiple times on the same results page is another. We did both, and got TDMC cited by AI models along the way.
TDMC pulled in 640,000+ search impressions across 160+ indexed pages over six months, with 579,670 impressions in Q1 2026 alone, a 9x quarter-over-quarter jump. Content published through the DAP retainer ranked on page 1 of Google for competitive pregnancy and oral health keywords. The canker sores page alone generated 125,647 Q1 impressions at position 3.75. Mouthwash safety: 87,858 Q1 impressions. Pregnancy tooth pain remedies: 109,076. Three pages doing the heavy lifting while the rest of the site kept climbing.
TDMC now owns 38% of the search conversation for tracked oral-systemic health topics. The climb was steady: 11% in November, 15% in December, 19% in January, 25% by late February, and 38% by May 2026. Nearly two of every five search results in the space now belong to TDMC. For a site that didn’t exist in search eight months earlier, that’s more than a third of the market captured before competitors could react.
By May 2026, TDMC held 96 Top 10 rankings and 34 Top 3 rankings, with 11 #1 rankings reached at peak in late February. The growth has been continuous: Top 10 keywords nearly quintupled between November and February, then doubled again between February and May. Top 3 rankings climbed from 12 to 34 across Q1 and Q2. Once Google started treating TDMC as an authority in oral-systemic health, the rankings compounded fast and have kept compounding.
TDMC’s content is now cited across every major AI platform: Google AI Overview (137 citations), Grok (10), Gemini (9), Perplexity AI (7), and ChatGPT (1), a 17x increase in just six months (the original count was 8 AI Overview citations in Q4 2025). When patients ask AI assistants about pregnancy and oral health, dental infections and blood pressure, or oral-systemic connections, TDMC shows up as the source. That matters because AI-powered search is growing fast, and the sites getting cited now are building an advantage that’s hard to replicate later.
DAP’s performance audit uncovered 4,000 to 6,000 additional clicks across 47 ranking pages that existing titles and meta descriptions were failing to capture. The canker sores page alone had 82,221 impressions at position 4.2 but only a 0.5% CTR, meaning 2,220+ clicks were going to competitors. The mouthwash safety page: 1,585 missed clicks. Pregnancy tooth pain: 1,086. DAP delivered a page-by-page CTR optimization roadmap targeting the highest-value gaps first.
Dr. Chuck’s YouTube channel reached 768,244 people in Q1 2026, 7x Q4 reach. Q1 watch time grew 19% to 556 hours, the channel added 279 new subscribers (bringing the total to 627), and the top video, “She Stopped Blood Pressure Meds After We Pulled One Tooth,” pulled in 7,357 views in Q1 alone. Cross-promotion between YouTube and the content clusters turned each search visitor into multiple touchpoints with Dr. Chuck’s message.
