How much should a dentist spend on Google Ads? (2026 guide)

Why there is no single "right" dental ads budget

Dentists ask me this question more than any other. The honest answer is that the right budget depends on three things:

• Which treatment you want to grow. An implant patient is worth thousands of dollars, so a higher cost per lead still pays. A check-up patient is worth less, so you need cheaper leads.
• How competitive your area is. A practice in a busy city centre competes with many other dentists for the same searches. A suburban or regional practice usually pays less per click.
• How good your landing page and front desk are. The same budget can bring twice the bookings if the page is clear and every call is answered quickly.

So instead of guessing, it is better to start from real cost-per-lead numbers and work backwards.

Real dental Google Ads costs by treatment

These ranges come from a combined report of the dental practices I manage (veneers, Invisalign and implant campaigns). In total these campaigns brought 5,041 leads at an average of $32.81 each.

A "lead" here means a phone call, booking or enquiry form. Your numbers will be different: area, competition, season and offer all change the cost.

In Australia, one of the strongest dental accounts I manage has brought 4,722 conversions at about A$35 each. That shows what a well-built account can do over time, but it took months of testing to get there.

What 13 dental accounts taught me about budget

I recently went through every keyword in 13 dental practice accounts I manage in Australia: A$147,255 of spend and 4,113 leads. A few lessons changed how I set budgets for new practices:

• Implant-focused practices get the cheapest leads. The two best implant accounts averaged about A$26 per lead. Practices running only veneers paid A$62 to A$103 per lead. If you offer both, I start the budget with implants.
• Veneers need about twice the budget for the same number of leads. Veneer clicks cost A$3.85 to A$4.83, against about A$2 for implants, and veneer leads averaged around A$62, against about A$30 for implants.
• Some keywords give far more for the same money. "Dental implants for seniors" brought 571 leads at A$24.56 each, the cheapest in all 13 accounts, yet only 8 of the 13 practices were using it.
• Broad match uses budget fastest. It took 41% of the spend, but each lead cost A$46.77, compared with A$30.07 on Exact match. I keep most of a new practice's budget on Exact and Phrase.
• Every treatment needs a "cost" ad group. Searches like "dental implants cost" and "veneers cost" were the second-biggest source of leads.

I've shared the full numbers, treatment by treatment, in Dental Google Ads cost: cost per click, cost per lead and budget by treatment.

How to work out your own budget (simple method)

Start with the number of new patients you want each month, then work backwards using a realistic cost per lead and booking rate.

Then ask: if only a quarter of those 40 enquiries book (10 patients), is one new Invisalign patient worth more than $140 to you? For most practices the answer is clearly yes, which is why high-value treatments are usually the best place to start.

If your budget is small (under $20 a day), focus on one treatment and one area. Spreading a small budget across every treatment means none of them gets enough clicks to learn what works.

What makes dental Google Ads cost more than it should

When I audit dental accounts, the same problems come up again and again:

1. One campaign for everything. Implants, check-ups and whitening share one budget, and the cheap searches use it all up.
2. Missing negative keywords. Ads show for "dental assistant jobs", "dental school", "free dental care" and "cheap dentist" searches that never become patients.
3. Sending ads to the homepage. Someone searching "dental implants cost" should land on an implant page with prices, finance options and a booking button.
4. No call tracking. Many dental patients phone instead of filling a form. If calls are not tracked, Google cannot learn which keywords bring patients.
5. Ads running when nobody answers the phone. Emergency and call ads should follow your opening hours.
6. Breaking Google's health ad rules. Remarketing for implants and other restricted treatments is limited by Google, so those campaigns need to be built around search intent instead.

Fixing these usually lowers the cost per lead without adding a single dollar to the budget.

Google Ads or Facebook Ads for dentists?

Google Ads shows your practice to people who are already searching for a dentist, so it is the best place to start for implants, emergency dentistry and new patients ready to book.

Facebook and Instagram Ads reach people before they search. They work well for visual offers such as whitening, Invisalign and new-patient specials. Many practices start with Google, then add Facebook once tracking is in place.

How long before Google Ads works for a dental practice?

Search ads can bring calls in the first week. It usually takes 4 to 8 weeks of data and optimization to bring the cost per new patient down to a steady level. Judge the account on booked patients over a full month or two, not on the first few days.

Quick checklist before you set your budget

• Choose one or two treatments to grow first
• Set up call tracking and booking-form tracking
• Build a landing page for each treatment
• Add a negative keyword list from day one
• Start with $40 to $70 a day per main treatment and review after 4 weeks
