Every campaign in this guide so far has been built around one moment: a patient typing a search. The Isolation and Exploration campaigns catch that moment. Performance Max catches it too, and reaches a little further.
Demand Gen works differently. It shows your ads to people who are not searching for a dentist at all. They are watching a YouTube video, scrolling Discover on their phone, reading Gmail or browsing a website. Some of them will need a dentist soon. Most of them will not be ready for weeks or months. The job of Demand Gen is to make sure that when they are, your practice is a name they already know.
That makes it the most patient campaign in the account, and the easiest one to waste money on. This chapter covers what Demand Gen is, where it fits for a dental practice, what it really costs to run, and the healthcare rules that shape it.
Display Ads Didn't Disappear. They Moved Into Demand Gen.
Google describes Demand Gen as a campaign that serves ads "on YouTube, Discover, Gmail, and the Google Display Network," including YouTube Shorts, the YouTube home feed and the videos people watch next. It runs on images and video, not keywords.
If you have heard of Google Display ads, the banner and image ads that appear on websites across the internet, they are part of this now too. Google announced in May 2026 that Display ads have "a new home in Demand Gen," with a migration tool for existing Display campaigns and the move expected to be complete by 2027. For a practice starting today, display advertising means a Demand Gen campaign.
It Belongs at the Top of the Funnel, So It Comes Last
In Chapter 2 we laid out the funnel: people who do not yet know they have a problem, people researching options, and people ready to book. This whole guide has followed one rule. Start at the bottom, where people are ready to book, and work your way up.
Demand Gen sits near the top. It creates interest; it does not capture it. That is why it comes after everything else. Your search campaigns need months of real conversions before Google knows what a new patient looks like for your practice. Performance Max builds on that. Demand Gen builds on both. Launch it first, and you are paying to introduce your practice to strangers before you have proven you can turn the people already searching for you into patients.
Where Demand Gen Earns Its Place in a Dental Practice
Not every dental service needs a campaign that reaches people before they search. A patient with a toothache books today. But some services have long decision windows, and that is where Demand Gen helps.
- Implants, aligners and cosmetic work. As Chapter 2 showed, these are researched for weeks or months. A patient who has watched a short video of your dentist explaining implants, or seen your before-and-after work, has a head start on trusting you before they ever search.
- Families new to the area. Every household that moves to town needs a new dentist. Google lets you reach people around life events like a recent move, which is exactly when a family starts looking.
- Putting a face on the practice. Most dental websites look alike. A 30-second video of your dentist, your team and your office does something a search ad cannot: it lets people meet you before they call.
Start with two ad groups, not ten
Keep the first one small and specific. One ad group runs on YouTube only, with a short video of your dentist introducing the practice, shown to people in your area around a recent move. A second ad group runs on Discover and the Display Network, with real photos and a simple message about implant or aligner consultations, shown to people Google considers in the market for those services. Both send people to a page built for that message, not the homepage, and both use the same conversion actions as the rest of the account. That is enough to learn whether awareness advertising pays for your practice before you spend more on it. If one ad group clearly outperforms the other after a fair run, move the budget there rather than adding a third.
The Budget Math Most Practices Skip
Here is the part that decides whether Demand Gen makes sense for your practice at all.
Google's own guidance for Demand Gen is to set a daily budget of "at least 10 times your target CPA" when you bid toward a target cost per conversion. It also says the campaign needs about 50 conversions to get through its learning phase, and that you should change bids and budgets gradually, around 5% to 10% a week.
Run those numbers for a dental practice. If a new-patient lead costs $200, ten times that is $2,000 a day. Even Google's lighter approach, bidding for volume without a target, comes with a recommended daily budget of at least $100, about $3,000 a month, on a campaign that will not produce search-level lead costs.
For most single-location practices, the honest answer is to wait. Fund the search campaigns that catch patients ready to book, add Performance Max when the account is ready, and come to Demand Gen when those are fully funded and you still have budget to build awareness. For a larger practice, a group with several locations, or one pushing hard on implants or aligners, Demand Gen can make sense sooner, as long as the budget can carry it through learning.
You Can Finally Tell Demand Gen Where to Run
Demand Gen used to decide on its own where to show your ads. It no longer has to. Google now offers channel controls at the ad group level, so you can choose the channels for each ad group, or let Google use all of them.
For a dental practice, this is useful. A video-first ad group can run on YouTube only, where a short introduction from your dentist belongs. An image ad group can run on the Display Network or Discover. If you want a set amount to go to a specific channel, Google's own suggestion is to give that channel its own ad group.
Locations work the same way as the rest of the account: set the area your patients actually come from. In Demand Gen you set location at either the campaign or the ad group level, not both.
Healthcare Rules Take the Best Audiences Off the Table
Demand Gen is built around audiences, and this is where healthcare changes the picture most.
Google offers a long list of audience options in Demand Gen: custom segments, in-market audiences, life events, detailed demographics, affinity audiences, your own data such as website visitors and customer lists, optimized targeting and lookalike segments. For most businesses, the most powerful of these are the ones built from their own customers.
For dental ads, Google's health policy for personalized advertising takes several of those off the table. For sensitive health content, which Google defines to include "invasive medical procedures, including cosmetic surgery, surgical procedures, or injections," it does not allow your own data segments, customer lists, audience expansion or lookalike segments. Custom segments are limited to Display, shown to non-sensitive audiences or contextually. That covers services like implants and oral surgery, and it means remarketing to people who watched your videos or visited your implant page is out.
What remains still works:
- Life events, such as a recent move.
- In-market and affinity audiences related to the services you offer.
- Demographics, used the careful way Chapter 9 describes.
- Location, always.
In practice, that means dental Demand Gen campaigns lean on broad, well-chosen audiences and strong creative, rather than the tightly targeted retargeting other industries use. Expect it, and plan the creative accordingly.
The Creative Is the Campaign
In search, the words of the ad do most of the work. In Demand Gen, the pictures and video do. People are scrolling past your ad while doing something else, and you have a second or two to earn a pause.
Google's guidance is to give each campaign at least three images, in vertical, square and horizontal shapes, and a video for each shape, including vertical video for YouTube Shorts. For a dental practice, the best material is usually already walking around your office:
- Your dentist, on camera. A short, relaxed introduction: who they are, what they care about, what a first visit is like.
- Your office and team. Real rooms, real people, real light. Stock photos of perfect smiles look like every other dental ad on the internet.
- Patient stories, only with clear written permission, and never in a way that reveals health details a patient has not agreed to share.
- One clear next step, such as booking a visit or a consultation, on every ad.
A phone and a quiet afternoon are enough to start. What matters is that it looks like your practice, not a template.
Judge It Like an Introduction, Not Like Search
Demand Gen will almost never match your search campaigns on cost per lead. That is not a sign it is failing. It is reaching people earlier, before they are ready, and many of the patients it helps create will eventually arrive by searching for your practice by name or calling directly.
So judge it fairly:
- Give it time. Let it get through learning, around 50 conversions by Google's count, before you draw conclusions, and change it gradually rather than rebuilding it every week.
- Look at conversions over weeks, not days.
- Watch your brand searches and direct calls. If Demand Gen is doing its job, more people will search for your practice by name, and your brand campaign from Chapter 6 will see it.
If after a fair run it is not moving any of those numbers, put the money back into the campaigns that catch patients ready to book.
Next, the Map Patients Look at First
There is one more place patients look for a dentist, and for many searches it appears above everything else on the page: the map, and the ads that sit on and above it.
That is Chapter 12, Local Ads and Google Maps.
If you are ready to reach patients before they search, we build Demand Gen for dental practices that have the search foundation to support it, and we will tell you plainly if you are not there yet. Our Google Ads management follows the same rollout as this guide.
