How does ChatGPT decide which dentist to recommend?
ChatGPT retrieves candidate businesses through Bing's index, then favors practices with consistent information across platforms, a rating around 4.3 stars or higher, and recent reviews. It also pulls from business-data providers and community sources. Strong Bing presence plus consistent details and fresh reviews is the combination that gets a clinic named.
Unlike a Google search, ChatGPT doesn't return a page of links you scroll through. It synthesizes an answer and names a few businesses directly. That makes the stakes higher: being fourth is the same as being invisible. Understanding the pipeline — retrieval, then selection — is what lets you influence it.
Does ChatGPT use Google? No — it uses Bing
ChatGPT search relies on Bing's index, not Google's. Analyses show roughly 87% of AI citations align with Bing's top results, versus about 56% for Google. This is the single most misunderstood fact in dental AI marketing: a practice can rank well on Google and still be completely absent from ChatGPT.
The practical consequence is that your Google rankings tell you almost nothing about your ChatGPT visibility. If your site has never been submitted to Bing, ChatGPT has no reliable way to retrieve it — no matter how strong your Google SEO is.

The steps that get a clinic into ChatGPT
In order: allow AI crawlers in robots.txt, get indexed in Bing via Bing Webmaster Tools and IndexNow, add LocalBusiness and Dentist schema, raise your review rating above roughly 4.3 stars, keep reviews fresh, and make your name, address and phone identical across every platform. Reviews and consistency usually matter more than any single technical change.
- Open robots.txt to AI. Confirm OAI-SearchBot, GPTBot and ClaudeBot are not blocked.
- Get into Bing. Set up Bing Webmaster Tools, submit your sitemap, enable IndexNow, and submit key pages manually.
- Add structured data. Implement LocalBusiness, Dentist and FAQ schema so AI understands your practice.
- Clear the rating floor. Build genuine reviews until your average sits comfortably above ≈4.3★.
- Keep reviews fresh. A steady, recent flow signals an active, trusted practice.
- Make your details consistent. Identical name, address and phone everywhere — inconsistency lowers AI trust.
How long until ChatGPT shows my practice?
Once your pages are indexed in Bing, they can begin appearing in ChatGPT within days to a few weeks. The technical foundation is quick; building the review and consistency signals that make ChatGPT confident enough to recommend you compounds over a 30 to 90 day window. No one can guarantee a specific position.
New domains and practices with thin review profiles sit toward the slower end of that range. The fastest wins usually come from clinics that already have good reviews and simply weren't indexed or structured correctly — for them, the fix can surface quickly.
