Established practices generally run 4-7% of gross revenue. New practices in their first year or two commonly spend far more — published guidance ranges from 6-10% up to 15-20% — because empty chairs cost more than marketing does. But the percentage matters less than what a patient costs you and what a patient is worth.
The published ranges cluster tightly for established practices and diverge sharply for new ones.
This is where the percentage stops being useful and the arithmetic starts.
Reported acquisition costs run roughly $150-$300 for general dentistry and $400-$800 for implant and cosmetic cases. The variance is the point: high-value cases cost more to acquire and are worth it.
Average annual revenue per patient multiplied by how long they stay. A patient generating around $650 a year over seven years is worth roughly $4,500 — which reframes a $300 acquisition cost entirely.
Many practices convert only a minority of inbound calls to appointments. Fixing that costs nothing in ad spend and changes every other number on this page.
Referrals account for a substantial share of new patients at established practices, and referred patients convert at far higher rates than advertising-generated ones. The same signals that drive referral now drive AI recommendation.
