Your dental Google Ad went through. You set up the campaign, wrote the headlines, launched it — and then got a disapproval notice. The ad copy looked fine to you. So what happened?
The answer is almost always the same: you ran into two rulebooks at once, and only knew about one of them.
Google has its own advertising policies. Your provincial dental regulatory body has its own advertising guidelines. These are two separate sets of rules, written by two separate organizations, and both apply to every ad your dental practice runs. Most Canadian dentists — and many marketing companies managing their accounts — are only familiar with one of them.
This post is for dental practice owners and anyone managing Google Ads campaigns for a Canadian dental clinic. It explains what both rulebooks actually say, why your ad likely got flagged, and how to write ad copy that satisfies both Google and your provincial regulator at the same time.
Key Takeaways:
- Dental Google Ads in Canada must comply with two separate sets of rules: Google’s advertising policies and your provincial dental college’s advertising guidelines
- Google checks ad copy, assets, keywords, and the landing page — a disapproval can come from any of these, not just the headline
- The RCDSO and other provincial colleges prohibit superlatives, guaranteed results, incentive offers, and comparisons with other practices
- Ad copy that is entirely factual, objective, and verifiable will satisfy both Google and provincial regulators simultaneously
- When an ad is disapproved, the first place to check is Google’s Policy Manager — the specific policy details column tells you exactly what triggered the flag
The Two Rulebooks Every Canadian Dentist Must Follow
Rulebook One: Google’s Advertising Policies
Google’s advertising policies apply to every business running ads on the platform. For dental practices, the most relevant policies involve healthcare claims, editorial standards, and misrepresentation.
Google’s automated systems scan ad copy, assets, keywords, and the destination landing page. A disapproval can be triggered by the ad headline, a phrase in the description, an image asset, or by a disconnect between what the ad promises and what the landing page delivers. Most practices assume the disapproval is about the headline — often it is not.
Rulebook Two: Provincial Dental College Advertising Guidelines
Dentistry in Canada is regulated provincially. The rules governing what dentists can and cannot say in advertising are set by individual provincial colleges — the Royal College of Dental Surgeons of Ontario (RCDSO) in Ontario, the College of Dental Surgeons of Alberta (CDSA) in Alberta, and their equivalents elsewhere.
This is where most Canadian dentists get caught off guard. A significant portion of digital marketing strategies — and many marketing agencies — originate from the United States, where dental advertising rules are far more permissive. What is standard practice in an American dental Google Ad can be a direct regulatory violation in Ontario or Alberta. The agency managing your campaigns may not know Canadian dental advertising rules. You are still responsible for the content.
What a Compliant-Looking Ad That Isn’t
Here is a real example of dental ad copy that reads as standard marketing to most people — but would trigger flags from both Google Ads and the RCDSO simultaneously.
Headline 1: Tired of Missing Teeth? Headline 2: Top Dental Implant Clinic Headline 3: Get a Permanent, Painless Smile Description 1: Our state-of-the-art office uses cutting-edge technology to restore your confidence. Description 2: Book a consultation today and get a free take-home teeth whitening kit!
Why the RCDSO Flags This Ad
Superlative and superiority claims. “Top Dental Implant Clinic,” “state-of-the-art,” and “cutting-edge technology” are all prohibited under RCDSO advertising guidelines. The college forbids dentists from claiming uniqueness, superiority, or implying their services or equipment are better than a colleague’s. These phrases appear reasonable in general marketing — in Ontario dental advertising, they are violations.
Guaranteed results. Promising a “Permanent, Painless Smile” creates unrealistic patient expectations. No dental procedure is guaranteed to be painless, and implants can fail. The RCDSO prohibits outcome guarantees in advertising because they mislead prospective patients about what they can expect from treatment.
Prohibited incentives. The offer of a “free take-home teeth whitening kit” is a significant violation. Ontario dentists are prohibited from running incentive programs, giveaways, contests, or offering free or discounted products to attract new patients. This rule exists regardless of where the offer appears — including in Google Ads.
Undisclosed registration status for specific procedures. When an ad highlights dental implants specifically, the RCDSO requires that general practitioners explicitly state their registration status — for example, “Services provided by a general dentist” — so patients understand who is performing the procedure. Omitting this is a violation.
Why Google Also Flags This Ad
The “painless” health claim. Google’s healthcare policies flag speculative or unverifiable clinical claims. Promising a procedure is “painless” or yields “permanent” results is treated as a misleading health declaration and can trigger disapproval under the Healthcare and Medicines policy.
Responsive Search Ad misalignment. Google rotates Responsive Search Ad headlines in different combinations. If “Top Dental Implant Clinic” and “Get a Permanent, Painless Smile” appear together without additional context, the ad may fail Google’s editorial standards for clarity about what is actually being offered.
Landing page disconnect. If a user clicks an ad expecting a free teeth whitening offer and the landing page omits or buries that offer — perhaps because the practice knows it cannot legally fulfil it — Google flags the account for misrepresentation. The ad and landing page must match. If the offer cannot appear on the landing page, it cannot appear in the ad.
What Google Actually Checks When It Reviews Your Ad
When a dental ad is disapproved, the first place to look is the Policy Manager inside your Google Ads account. The specific policy details column identifies exactly what triggered the disapproval — whether it was the ad copy, an asset, a keyword, or the landing page.
Most practices check only the headline when an ad is disapproved. In practice, the trigger is often elsewhere:
- Ad copy: a phrase in a description line, not just the headline
- Assets: a sitelink or callout extension that contains a prohibited claim
- Keywords: a keyword in an ad group that conflicts with Google’s sensitive categories
- Landing page: content on the destination page that violates policy — even if the ad copy itself is clean
The policy that triggered the disapproval is named in the Policy Manager. Reading it precisely tells you where to make the fix, rather than guessing.
One thing many practices do not realize about Google’s disapproval system: the review is not purely manual. Automated systems scan your ad and landing page against a policy database, and the flags they produce are sometimes inconsistent or overly broad. An ad that was approved last month may be disapproved when re-submitted after a minor edit, because the automated review catches something it previously missed.
If a disapproval seems incorrect — your ad copy is factual and your landing page is clean — you can request a manual review through the appeal process in your Google Ads account. Manual reviews take longer than automated ones but apply more nuanced judgment to edge cases. For dental practices dealing with a recurring disapproval on compliant ad copy, appealing for manual review is often the right next step.
The One Rule That Satisfies Both Regulators at Once
The single most effective rule for writing dental Google Ads in Canada — the rule that keeps you compliant with both Google and your provincial college simultaneously — is this:
Write only what is factual, objective, and verifiable. Remove every subjective claim, superlative, and result guarantee.
When your ad copy describes only what your clinic actually offers — your location, your services, your hours, your registration status — you eliminate the violations that trigger both Google’s automated systems and the RCDSO’s advertising guidelines at the same time.
Practically, this means:
- Replace “Top Dental Implant Clinic” with “Dental Implants in [City] — Book a Consultation”
- Replace “Permanent, Painless Smile” with “Dental Implants for Missing Teeth — [City] Dentist”
- Replace “state-of-the-art” with nothing — remove it entirely and use the space to state a specific service or location
- Remove all incentive offers from ad copy
- Add your registration designation where required by your provincial college
This approach is not just about staying out of trouble. Factual, specific ad copy targeted to high-intent searches also performs better. Potential patients searching for dental implants in a specific city are not looking for superlatives — they are looking for a credible provider close to them. Precise ad copy that matches their search intent converts more reliably than copy built on claims that cannot be substantiated.
Structuring Your Dental Google Ads Campaigns to Reduce Disapproval Risk
Segment Campaigns by Treatment Type
Mixing dental implants, teeth whitening, emergency dentist, and general checkups into a single ad group creates two problems: targeting becomes imprecise, and any disapproval in one ad affects the entire group. Segment campaigns by service. Each ad group should target a specific service with its own relevant keywords, its own ad copy, and its own dedicated landing page.
This also improves performance. Campaigns segmented by treatment type allow budget allocation to reflect service demand — a dental practice may spend more on implants than on whitening because the patient value is higher, and segmented campaigns make that control straightforward.
Match Landing Pages to Ad Copy
Sending traffic to your homepage from a Google Ad is one of the most common reasons dental Google Ads underperform. A patient who clicked an ad for emergency dental care and lands on a general homepage has to find what they were looking for — and most will not.
Each ad group should send traffic to a specific landing page that matches the search intent. An ad for dental implants goes to a dental implants page. An ad for emergency dentist services goes to an emergency contact or booking page. Conversion tracking should be set up to track phone calls and form submissions, not just clicks, so you can evaluate which landing pages are actually generating patient bookings.
Use Negative Keywords to Protect Ad Spend
Negative keywords filter out searches that are not relevant to the services you offer. A dental practice running implant ads without negative keywords may be paying for clicks from people searching for veterinary implants, dental school programs, or DIY dental kits. None of those searchers are potential patients.
Reviewing search term reports regularly and adding irrelevant terms as negative keywords keeps ad spend focused on the right audience. This is one of the highest-impact optimizations available to dental PPC ads and is frequently overlooked.
Set Geographic Targeting Precisely
Location targeting should be focused on the actual area your patients come from. For most dental clinics, this means targeting within a defined radius of the clinic location rather than a broad city or region. A patient actively searching for a dentist is almost always looking for one nearby — overly broad geographic targeting wastes ad spend on users who are too far away to become patients.
Frequently Asked Questions
Why was my dental Google Ad disapproved?
Disapprovals can be triggered by ad copy, assets like sitelinks or callout extensions, keywords in the ad group, or content on the landing page. Check Google’s Policy Manager under the specific policy details column — it identifies exactly what triggered the flag.
Do Canadian dental Google Ads need to follow provincial college rules?
Yes. In Canada, dental advertising is regulated provincially. The RCDSO governs Ontario dentists, the CDSA governs Alberta dentists, and other provinces have equivalent bodies. These rules apply to all advertising including Google Ads, regardless of whether your marketing agency is Canadian or not.
What ad copy is prohibited for Canadian dentists?
Superlatives (“top,” “best,” “most advanced”), guaranteed outcomes, incentive offers (free products, contests, discounts to attract patients), comparisons with other practices, and unsupported superiority claims are all prohibited under guidelines like the RCDSO’s. These restrictions apply across all advertising including Google Ads.
How do I write dental Google Ad copy that won’t be disapproved?
Limit copy to factual, objective descriptions of the services you offer, your location, your hours, and your registration status. Avoid all outcome guarantees, superlatives, and incentive offers. This approach satisfies both Google’s advertising policies and Canadian provincial dental advertising guidelines simultaneously.
What is the best structure for dental Google Ads campaigns?
Segment campaigns by treatment type, with each ad group targeting specific services and sending traffic to a matching landing page. Set up conversion tracking for phone calls and form submissions. Use negative keywords to eliminate irrelevant searches, and focus geographic targeting on your actual patient catchment area.
How long does it take for a disapproved Google Ad to be reinstated?
After fixing the issue and submitting for review, most ad reviews complete within one business day. Complex policy issues or landing page violations may take longer. If the ad remains disapproved after a fix, the Policy Manager will indicate whether an appeal is available.
