Dental Practice Net Promoter Score: What a Good NPS Is and How to Use It
Net Promoter Score is one question: "How likely are you to recommend this practice to a friend, 0 to 10?" Score it by taking the percentage who answer 9 or 10 (promoters) and subtracting the percentage who answer 0 through 6 (detractors). The 7s and 8s don't count either way.
The benchmark
Most dental practices that survey consistently land between 50 and 70. Above 70 means your patients are actively selling for you. Between 30 and 50 is fine but forgettable. Below 30 means something specific is broken, usually wait times, billing surprises, or a front desk that sounds rushed.
Don't trust a single month of data. You need at least 30 responses before the number means anything. A 4-operatory practice seeing 300 patients a month with a 25% survey response rate gets there in about 2 weeks.
Why the number is worth money
Referred patients are the cheapest patients you'll ever get, usually $25 to $75 each once you count the cost of running a referral program. Compare that to $300 to $600 per new patient from Google Ads. We break down the full math in our cost per acquisition benchmark.
A practice with an NPS of 70 doesn't need to outspend competitors on marketing. A practice at 30 is paying retail for every new chart.
How to run it without annoying anyone
Text the survey within 2 hours of the appointment, while the visit is still fresh. Most patient communication platforms in the $300 to $600/month range include NPS or a close cousin of it, so this often costs you nothing extra.
Keep it to the one question plus an optional comment box. Response rates run 20% to 30% by text and closer to 5% by email.
What to do with the answers
Call every detractor within 48 hours. Not to argue, just to listen. About half of them will soften once someone acknowledges the problem, and you'll hear the same 2 or 3 complaints on repeat. Those repeats are your fix list.
Ask promoters for a Google review while they're warm. A 9 or 10 who just told you they'd recommend you will usually do it in writing if the link is one tap away.
One caveat: NPS tells you patients like you. It doesn't tell you they're accepting treatment. If your score is high but production is soft, look at your exam-to-treatment conversion rate instead. Different problem, different fix.
