The Real Cost of Missed Calls at a Dental Practice

September 18, 2026 · Sebastian Dutra · 3 min read

Key Takeaway

Most dental practices miss between 25% and 35% of inbound calls, and a meaningful share of those are new patients who simply call the next practice on the list. For a typical single-location practice that works out to five figures a month in lost production — a number you can calculate from your own phone logs in about ten minutes.

Missed calls don't show up anywhere in your practice management reports. There's no line item for the new patient who called at 6:40pm, got voicemail, and booked with the practice two miles away instead. That invisibility is exactly why the problem persists in practices that are otherwise well run — you can't manage a number you never see.

Where the calls actually go missing

  • After hours, evenings, and weekends — when a large share of patients actually have time to call
  • During lunch, when the front desk is covered by one person or nobody
  • The second and third lines ringing while your coordinator is checking a patient in
  • Hold time — a caller who waits more than about 90 seconds typically hangs up and calls someone else

The common thread is that none of these are performance problems. Your front desk isn't doing anything wrong; there is simply one of them and several phone lines, and they cannot be on the phone and with a patient at the same time.

Running the number for your practice

The math is straightforward, and it's worth doing with your own figures rather than accepting an industry average. Pull the missed-call count from your phone system for a normal month, then work through four steps.

  • Missed calls per month — from your phone provider's call logs
  • What share were new patients — typically 20% to 30% of inbound calls at an established practice
  • What share you would have converted — use your actual booking rate, not an optimistic one
  • Average first-visit production for a new patient — from your PMS, not an industry estimate

A worked example, using deliberately conservative inputs: a practice missing 10 calls a day across 22 business days misses 220 calls a month. If 25% are new patients, that's 55 new-patient calls. Convert 40% of those and you have 22 new patients. At $800 in average first-visit production, that's roughly $17,600 a month — before any of the treatment those patients would have gone on to accept.

The number that matters isn't the industry average. It's what your own phone logs say, multiplied by what a new patient is actually worth in your practice.

Why this compounds

A missed call isn't a deferred call. Someone with a cracked tooth or a suddenly available afternoon does not leave a voicemail and wait — they call the next practice on the search results page. So the loss isn't just the first appointment; it's that patient's hygiene recall, their treatment plan, and the referrals they would have made, all of which now belong to a competitor.

It also quietly undermines everything upstream. Money spent on ads, SEO, and referral relationships is spent to make the phone ring. If a third of those rings go unanswered, roughly a third of that marketing budget is being spent to generate leads for whoever picks up on the second try.

What to do about it

Start by measuring, because most practices materially underestimate the number. Ask your phone provider for a missed-call report covering a full month, broken out by hour — the after-hours and lunchtime concentration is usually the part that surprises people.

From there the options are the familiar three: add front-desk headcount, which helps during business hours and does nothing at 9pm; use an answering service, which captures a message but can't book; or put an AI receptionist on the lines that currently go to voicemail, which answers every call around the clock and books directly into your schedule. Which one makes sense depends on where your missed calls are actually concentrated — which is why the measuring step comes first.

Frequently Asked Questions

Most practices miss somewhere between 25% and 35% of inbound calls once after-hours, lunch, and overflow are all counted. Practices are usually surprised by the figure because missed calls don't appear in any standard PMS report.
Often not. A patient calling about pain or trying to book around a specific window will typically move on to the next practice rather than wait for a callback, which is why after-hours coverage tends to be worth more than it looks.
Request a missed-call report from your phone provider for a full month, ideally broken down by hour of day. That tells you both the volume and where in the week it's concentrated, which determines what the right fix is.
