The short answer: a percentage of revenue
A common benchmark is that an established dental practice spends roughly 3 to 5 percent of gross revenue on marketing, while a newer practice trying to fill the schedule spends more, often 5 to 10 percent, until it reaches capacity.
That range is a starting point, not a rule. The right number depends less on a formula and more on where you are and what you are trying to grow.
It depends on your stage
A brand-new practice with open chairs has a very different job than a booked practice trying to attract higher-value cases. Match the budget to the goal.
- Startup or relocation: spend aggressively to build visibility and awareness fast, often at the top of the range.
- Growth: you have patients but want more of a specific type, so weight the budget toward focused SEO and treatment-specific campaigns.
- Established and full: spend to protect visibility, keep reviews fresh, and replace natural patient attrition.
Where the money should actually go
A budget number means little without a sensible split. The mistake most practices make is pouring everything into ads while ignoring the website and profile those ads depend on.
A durable mix funds the foundation first, then traffic. Your Google Business Profile and a fast, conversion-focused website are what turn clicks into booked chairs, so they come before you scale spend.
- Foundation: a fast, mobile-first website with an easy booking path.
- Local SEO and Google Business Profile management for Map Pack visibility.
- Focused Google Ads for high-intent, high-value treatments.
- A steady review-generation routine, which costs little but drives a lot.
How to tell if your budget is working
Spend is only meaningful next to what it returns. The metric that matters is not clicks or impressions, it is cost per new patient, and the lifetime value of that patient against what you paid to acquire them.
If a new implant patient is worth thousands and you acquired them for a fraction of that, the spend is working regardless of the raw budget. If you cannot trace spend to booked patients at all, the problem is measurement, not the amount.
The costs that never appear in the budget
Most practices budget for the visible line items, the ad spend and the agency retainer, and then lose a meaningful share of the return to things that were never costed at all.
The largest is unanswered enquiries. A campaign that produces thirty calls a month is worth whatever fraction of those calls actually gets answered, and for most practices that fraction drops sharply outside surgery hours and during the lunch period. A missed call from a paid click is money spent to reach a patient who then rang somebody else. Before increasing a budget, it is worth knowing what your answer rate looks like on a Tuesday at 1pm.
The second is slow follow-up. Enquiries that arrive by form rather than phone decay quickly, and a patient who filled in a form on Friday afternoon has usually booked elsewhere by Monday morning. This costs nothing to fix and is routinely the single highest-return change available to a practice.
The third is untracked spend. If calls and forms are not attributed to a source, every budget decision after the first is guesswork, and the natural tendency is to keep funding whatever was running when things felt busy. Tracking is not an optional refinement on top of a campaign, it is what makes the budget a decision rather than a habit.
None of these require more money. They require that the money already committed reaches a practice able to catch what it produces, which is why we look at answer rates and follow-up before recommending any increase in spend.
There is a useful test here. Take last month's total marketing spend and divide it by the number of new patients who actually sat in a chair, not the number of enquiries received. Most practices doing this for the first time find the figure is higher than they assumed, sometimes by a factor of two, because the gap between an enquiry and an attendance is wider than anyone tracks. That single number is more useful than any percentage-of-revenue benchmark, because it is yours, and because it tells you immediately whether the constraint is the budget or everything that happens after the phone rings.
