Most dentists who have heard about AI search assume they are dealing with a single system. They think: Google uses AI now, so if I rank on Google, I am covered. That assumption is costing them patients.
Google actually operates two distinct AI systems that patients use in very different ways. One sits inside Google Search. The other is a standalone chatbot. They pull from different sources, surface different practices, and require different strategies to appear in. A practice that shows up confidently in one can be completely absent from the other — and most practice owners have no idea which side they are on.
What Is Gemini?
Gemini is Google’s standalone AI assistant, available at gemini.google.com. Patients use it the same way they use ChatGPT — to ask questions, get recommendations, and research options before making a decision.
When a patient opens Gemini and asks “What’s the best family dentist in [city] who accepts Aetna?”, Gemini composes a response by drawing on web content it has indexed. In Seeniq’s audit data, 52% of Gemini’s citations link to first-party website content — meaning Gemini heavily favors what is directly on your practice website when constructing its answer.
This matters. If your website has thin content, outdated procedure pages, or no clear description of the services you offer, Gemini may not mention you at all. Or it may mention you with the wrong details.
Patients who use Gemini are motivated searchers. They have opened a separate tool, typed a specific question, and are actively looking for guidance. 26% of patients say AI directly influenced their provider choice — and Gemini is a major part of that influence chain.
What Is Google AI Overview?
Google AI Overview — the AI-generated answer box that appears at the top of Google Search results — is a completely separate system. Patients encounter it without intending to. They type “dental implants [city]” and before any regular links appear, an AI-generated paragraph summarizes the topic, often pulling from multiple sources.
Healthcare has the highest Google AI Overview trigger rate of any industry at 88%. Procedure-specific queries trigger AI answers almost every time. “Dental implants,” “teeth whitening,” “Invisalign in [city]” — these terms reliably produce a Google AI Overview answer at the top of the search page.
But here is the critical distinction: location-based searches do not trigger Google AI Overview the same way. “Dentist near me” or “family dentist [city]” produce traditional local pack results, not AI answers. Google AI Overview is primarily a procedure-and-information channel, not a directory channel. Patients use it to understand what they need before deciding where to go.
This means Google AI Overview and Gemini serve different patient moments — and visibility in one does not guarantee visibility in the other.
Why Your Practice Might Show Up in One and Not the Other
The two systems favor different signals.
Gemini favors website structure and content. If your website has well-written procedure pages, clear language about what conditions you treat, and structured information about your practice — Gemini can cite it. If your website is a single homepage with five sentences and a phone number, Gemini has nothing to work with.
Google AI Overview favors citation authority and directory data. When building AI answers for procedure queries, Google draws heavily on directory listings, NPI Registry data, and how consistently your practice information appears across the web. A practice with inconsistent NAP (name, address, phone) across directories — or one that has never claimed its NPI listing — is at a structural disadvantage regardless of what is on its website.
Here is what this looks like in practice:
A dentist who invested in their website but neglected their directory presence may show up when a patient asks Gemini a direct question — but be invisible in the Google AI Overview answer when that same patient searches “dental implants” in their city.
Conversely, a practice with strong directory presence but a minimal website may appear in Google AI Overview but give Gemini nothing meaningful to recommend.
Seeniq’s monitoring data consistently surfaces this split. ChatGPT drives 87.4% of AI referral traffic — but Google AI Overview and Gemini shape patient decisions earlier in the journey, before they ever click anything. Missing from either means missing a meaningful segment of new patient volume. For a deeper look at how AI search works across all platforms, see our complete GEO guide for dental practices.
What You Can Do
The fixes for each system are concrete.
For Gemini visibility
- Add dedicated procedure pages to your website — one per major service. A page specifically about dental implants, one for Invisalign, one for cosmetic dentistry. These give Gemini structured content to cite.
- Make sure each page clearly states the procedure, who it is for, and your practice’s approach. Thin pages with two paragraphs do not provide enough signal.
- Include your city and neighborhood naturally in page content so Gemini can associate your practice with the right geography.
For Google AI Overview visibility
- Claim and verify your NPI listing at npiregistry.cms.hhs.gov if you have not already. NPI data is one of the most trusted sources for healthcare AI systems.
- Audit your directory listings: Google Business Profile, Yelp, Healthgrades, Zocdoc, Vitals, and others. Name, address, and phone should be identical across all of them — no abbreviations, no suite number variations.
- Check that your specialty categories are consistent. “General Dentistry” in one directory and “Family Dentist” in another creates conflicting signals.
For both
- Run an AI audit to see exactly what each platform is currently saying about your practice. Most owners discover errors they had no idea existed.
93% of dental practices are invisible in AI recommendations. That number is not a reflection of care quality or reputation — it is a reflection of the fact that AI visibility requires a different kind of attention than traditional SEO, and most practices have not made that shift yet.
The Practical Takeaway
Google AI Overview and Gemini are not the same thing. They represent two separate patient journeys: the active researcher using a standalone chatbot, and the passive searcher who encounters an AI answer in the middle of a Google search. Both matter. Both require different inputs to appear in.
The practices gaining new patients through AI search right now treat Gemini and Google AI Overview as distinct channels, each with its own logic. Most of their competitors have not made that distinction yet.
