A dentist we spoke with had a number in her head for ads: 800 dollars a month. It felt responsible. Safe.
Her practice was doing a little over a million dollars a year.
So she was funding the growth of a million-dollar practice with the price of one crown a month — then wondering why new patients trickled in and the schedule had good weeks and dead weeks that felt like weather. The budget wasn't careful. It was too small to work, pointed at nothing in particular, and measured against the wrong number. Let's fix all three.
How much should a dental practice spend on ads?
Start from a percentage of revenue, not a gut feeling. The U.S. Small Business Administration's general guidance for small businesses is to put 7-8% of gross revenue toward marketing — more if you're growing hard.
Two honest caveats. First, that's a cross-industry rule, not a number pulled from dental data, so use it as a frame, not gospel. Second, it covers everything — website, follow-up tools, and media spend together, not just ads. But it does one useful thing right away: it turns "800 a month feels fine" into real math. A practice at a million in revenue lands around 70,000 to 80,000 dollars a year, roughly 6,000 to 7,000 a month across the whole marketing operation. That's the floor to reason from. Now the real question isn't the percentage. It's what each dollar brings back — measured in patients, not clicks.
What number should you actually chase?
Not cost per lead. Cost per new patient — and behind it, what that patient is worth over time.
This is the most expensive mistake we see practices make. They shop for cheap leads, celebrate a low cost per lead, and never notice how many of those leads never book, or book and no-show. Two practices can pay the identical price per lead; if one books and keeps a third of them and the other keeps a tenth, their real cost per patient is worlds apart. Leads don't fill chairs. Patients do. And dentistry has a gift most businesses don't: a new patient isn't one cleaning, they're years of visits plus the people they refer. So a cost per patient that looks scary next to a single appointment can be a steal next to a decade of them. Chase cost per new patient, weighed against lifetime value, and everything clarifies.
How do you set the budget from a revenue goal?
Work backward from the patients you need, not forward from what you're comfortable spending. Three steps, and you can do it on a napkin.
- Start with the goal. How much new revenue do you want this year, and what's an average new patient worth to you over time? Say you want 120 new patients.
- Work back to patients, then leads. If your front desk honestly books and keeps one in three of the leads a channel sends, 120 patients means about 360 good leads.
- Price it against cost per patient. Whatever it costs to produce one booked, kept patient in your market, times 120, is your ad budget for that goal. Not a vibe — a target you can hold the spend to.
Do this and the budget stops being a number you flinch at and becomes something you're buying specific patients with. You'll also spot instantly when a channel is underwater: if cost per new patient is higher than what a patient is worth to you, you don't have a budget problem, you have a funnel or a front-desk problem.
Can your dental ad budget be too big — or too small?
Both, and practices manage to make each mistake. Here's the shape of it:
| Monthly budget vs revenue | What usually happens | | --- | --- | | Way under (e.g. 800/mo on 1M revenue) | Too little data for the platform to learn; new patients trickle; cost per patient stays high | | The 7-8% zone, aimed at a real funnel | Platform can learn; cost per patient becomes measurable and improvable | | Big budget, missed calls and slow follow-up | More leads, same leak — you pay to lose them faster |
Look at the top and bottom rows — those are the traps. Starve the budget and the ad platform never gets enough booked appointments to figure out who your best patients are, so it keeps guessing and your cost per patient stays ugly. Flood the budget into a practice where the front desk misses calls and nobody follows up fast, and you just buy more leads to drop on the floor. The middle row is the target: enough spend to let the platform learn, aimed at a funnel and a front desk that actually book. If your leads come in and sit, book a free audit — more budget won't fix a follow-up leak, and we'll show you which one you have.
Should new-patient and big-case ads share one budget?
No — split them, because they don't behave alike. A general new-patient campaign and a campaign for a high-value service like implants or clear aligners cost different amounts to win and are worth very different sums per case.
Lump them into one line and you hide which one your money is really funding. You might be crushing it on implant consults while quietly losing money on general cleanings — and the blended average whispers that everything's "fine." Track cost per booked patient for each separately. Then feed the one that returns better in your market. Budgeting is just aiming, and you can't aim at a blur.
What good looks like when spend meets a real funnel
The point of all this isn't a bigger budget. It's spend that lands on a funnel built to book — clear offer, matched page, a front desk that answers fast — so every dollar is traceable to a patient. The pattern holds in any business, dentistry included.
A med spa we work with in Nice put about 620 euros of ad spend through a tight funnel over six weeks — clear offer, matched page, instant follow-up — and turned it into 193 leads at 3.21 euros each, and 88 paying clients. A 71x return. A dental case is a bigger ticket than a facial, and a patient's lifetime value dwarfs a single visit, so the raw numbers won't copy across. But the machine does: right budget, aimed at a funnel that follows up fast, judged on cost per booked patient. That's what turns dental marketing from a monthly gamble into a predictable line item.
The 30-Second Audit
Three yes/no questions about your dental ad budget. Answer them before you set next month's number.
- Is your budget set from a revenue goal and cost per new patient — not just what feels comfortable?
- Do you track cost per booked patient against lifetime value, split by campaign — instead of celebrating cheap leads?
- Is your spend enough for the platform to learn, aimed at a funnel and a front desk that answer in minutes?
If any answer was no, book a free audit — we'll pull your numbers and tell you exactly what's broken, even if you don't end up working with us.
Budget by revenue. Judge by patients. Everything else is noise.
