Negative Keywords Every Dental Google Ads Account Needs

Negative keywords tell Google which searches should never trigger your ads. In a dental account, they're the difference between paying for "dentist near me accepting new patients" and paying for "dental hygienist jobs near me." Both contain the word "dental." Only one fills a chair.

This article gives you a starter list of dental negative keywords sorted by category, explains the match type rules that trip people up, and lays out a 20-minute weekly routine for keeping the list current. If your ads are getting clicks but the phone isn't ringing, start here.

Why dental accounts need negative keywords more than most

Dental searches overlap with a lot of things that aren't patient searches. The same words show up when people look for jobs, schooling, home remedies, products, pet care and free clinics. Google's matching has gotten looser over the years, especially with broad match, so a keyword like "teeth whitening" can show your ad to someone shopping for whitening strips at a drugstore.

You can't prevent every bad click. You can stop paying for the same bad click over and over. That's what a negative list does.

How negative keyword match types work

Negative keywords use the same three match types as regular keywords, but they behave differently. This is the part most practices get wrong.

Negative type	Written as	Blocks searches that...	Example
Broad	jobs	contain all the negative's words, in any order	jobs blocks "dental jobs near me"
Phrase	"dental school"	contain the exact phrase in that order	blocks "best dental school in Texas" but not "school dental program"
Exact	[free dentist]	match the phrase exactly, with nothing added	blocks "free dentist" but not "free dentist near me"

The critical difference: negative keywords don't automatically cover close variants. A positive exact match keyword will match plurals and misspellings. A negative won't. If you block job, you haven't blocked jobs. If you block hygienist, you haven't blocked hygenist, a common misspelling. Add the variants yourself.

Our opinion: use broad match negatives for single words that are never relevant (jobs, salary, vet), and phrase match negatives for multi-word ideas where one of the words is still useful to you ("dental school" so you don't block "school" in "back to school checkup").

The starter list: dental negative keywords by category

Copy these into a shared negative keyword list so you can apply them to every campaign at once. Then edit for your practice using the next section.

Employment and careers

• jobs, job, hiring, career, careers
• salary, salaries, pay, wage
• resume, interview, internship, externship
• assistant, hygienist, hygenist, receptionist (see the caution below)
• "dental assistant," "dental hygienist," "office manager"
• indeed, glassdoor (job sites)

A caution on "hygienist": a patient might search "dental hygienist cleaning near me." That's rare compared with job searches, but check your search terms before blocking the single word. The phrase "hygienist jobs" is always safe to block.

Education and training

• "dental school," "dental schools"
• course, courses, class, classes, CE, "continuing education"
• certification, certificate, program, degree
• exam prep, "board exam," "how to become"
• textbook, anatomy, diagram

Research and DIY

• "how to," "why does," "what causes"
• symptoms, remedy, remedies, "home remedy"
• DIY, "at home," homemade
• pictures, images, video, Reddit
• wiki, definition, meaning

Be thoughtful here. "How much does a root canal cost" is a research query, but cost searchers can become patients if your page answers cost honestly. If you block "how much", you lose them. Many practices block "how to" and "what causes" but leave cost questions alone.

Products and supplies

• strips, kit, kits, gel, pen (whitening products)
• toothpaste, floss, mouthwash, Waterpik
• amazon, walmart, target, cvs (retail shoppers)
• adhesive, "denture glue," "denture cleaner"
• wholesale, supply, supplies, equipment, lab

Animals

• dog, dogs, cat, cats, pet, pets
• vet, veterinary, veterinarian, animal, horse

Pet dental cleaning is a real search category, and it can show up for broad terms like "teeth cleaning near me."

Wrong location

If you serve one city, people searching for dentists in a city two hours away can still see your ads, depending on your settings. Add distant city names you keep seeing in your search terms. Also review your location setting. Google's default setting includes people who have shown interest in your area, not just people who are in it or regularly there. Most practices only want the second group.

Negatives that depend on your practice

These aren't universal. Decide based on what you offer and who you want to attract.

Term	Block it if...	Keep it if...
free, cheap, low cost	you're fee-for-service or don't offer discounted care	you run a free consult offer or a membership plan aimed at uninsured patients
Medicaid, CHIP, state plan names	you don't accept them	you're in network
specific PPO names	you're out of network with that plan	you're in network
pediatric, kids	you don't see children	you're a family practice
orthodontist, braces	you don't offer ortho	you offer aligners or braces
oral surgeon, "jaw surgery"	you refer these out	you have a surgeon on staff
"24 hour," "open now"	you're closed nights and weekends	you have real after-hours coverage
"dental school clinic"	always	rarely relevant

A note on "free": if you advertise a free implant consultation, blocking the word free will block "free dental implant consultation," which may be a great search for you. Use phrase match negatives like "free dental clinic" and "free dental work" instead.

Mistakes that block good patients

Negative keywords can hurt you as much as they help. These are the errors to watch for.

1. Blocking a word you also bid on. If you add cost as a negative but run an implant campaign built around "dental implants cost," you've blocked your own ads. Google Ads will often warn you about conflicts, but not always clearly.
2. Blocking brand-new keywords too fast. Give a new keyword a few weeks of data before deciding its searches are junk.
3. Forgetting variants. Block job and jobs. Block hygienist and its misspellings, if you block it at all.
4. Applying lists to the wrong campaign. A campaign for low-cost dentures and a campaign for premium cosmetic work need different rules on "affordable."
5. Never reviewing the list. Services change. If you start accepting a plan you used to block, remove that negative.

A weekly 20-minute negative keyword routine

The starter list is only the beginning. The real list comes from what patients actually typed. Here's how to build it, in order:

1. Open Google Ads and go to the search terms report for the last seven days.
2. Sort by cost, highest first. The expensive irrelevant terms matter most.
3. For each irrelevant term, decide whether to block the whole idea (a broad negative like salary) or just the phrase ("dental hygienist salary").
4. Add negatives to your shared list if they apply everywhere, or to a single campaign if they don't.
5. Note any good searches you're not bidding on yet. These become new keywords.
6. Check that no new negative conflicts with an active keyword.

Do this weekly for the first two months of a new campaign, then every other week. It's the single most useful recurring task in a small practice's ad account, and it's something an office manager can learn in an afternoon.

For the other half of this work, choosing what to bid on, see the best keywords for dental Google Ads. If you're still setting up your account, start with our Google Ads playbook for dentists. And if you've added negatives but results are still weak, these common causes of underperforming dental ads are the next place to look. Wasted clicks also inflate what you pay overall, which we cover in how much Google Ads cost for a dental practice.

Frequently asked questions

What are negative keywords in Google Ads?

Negative keywords are words or phrases you tell Google to exclude, so your ads don't show when someone searches them. For a dental practice, typical examples are "jobs," "salary," "dental school" and "whitening strips." They stop you from paying for clicks from people who will never book.

How many negative keywords should a dental account have?

There's no fixed number. A new account might start with 100 or so from a starter list, then grow it based on the search terms report. What matters is that the list reflects the irrelevant searches your ads actually triggered, and that it's reviewed regularly.

Do negative keywords block misspellings and plurals?

No. Unlike regular keywords, negative keywords don't automatically include close variants. If you block "job," you also need to block "jobs." Add common misspellings and plural forms yourself.

Should I add "free" as a negative keyword?

Only if you never offer anything free. Blocking the single word "free" will also block searches like "free implant consultation," which may be valuable if you run that offer. Phrase match negatives like "free dental clinic" are usually a safer choice.

Where do I find which negative keywords to add?

Use the search terms report in Google Ads. It shows the actual searches that triggered your ads. Sort by cost, look for irrelevant searches, and add them as negatives at the campaign or account level.
