What missed calls actually cost a dental practice
A missed call is rarely a delayed booking. It is usually a patient who called three practices and booked with whichever one answered.
Work out your own number
Generic industry statistics are not worth much here, because the answer depends entirely on your call volume, your mix of new versus existing patients, and your average case value. The calculation is straightforward with your own data:
- Pull total inbound calls and answered calls for a month from your phone system. The gap is your missed volume.
- Estimate what share of missed calls were new patients — for most practices it is meaningfully lower than the share of total calls, but not trivially so.
- Apply your new-patient conversion rate for calls that are answered.
- Multiply by your average first-year patient value, not the value of a single appointment.
When calls actually get missed
The pattern is predictable, which is what makes it fixable:
- Lunch, when the desk is covered by one person or nobody.
- Checkout rushes, when a patient at the desk outranks a ringing phone — correctly.
- While your team is on hold with an insurer, which can be a long time.
- First thing Monday, the single heaviest call period for most practices.
- Immediately after hours, when people call on their way home from work.
Why voicemail does not recover them
A patient in pain, or one shopping for a new dentist, does not leave a message and wait. They call the next practice. Voicemail recovers existing patients with non-urgent questions — which is real, but is not where the lost revenue is.
What actually closes the gap
- Coverage during the known peaks rather than uniform staffing across the day.
- Someone who can book, not just take a message — the call has to end with an appointment.
- Online booking, which catches the after-hours segment but not the caller who wants to talk to a person.
- Measuring answer rate at all. Most practices do not know their number, and you cannot manage what nobody reports.
Start by measuring
Before changing anything, get one month of answered-versus-missed data by hour of day. The shape of that chart usually makes the decision obvious, and it frequently shows the problem is concentrated in a handful of hours rather than spread across the week.
Questions
What is a good answer rate for a dental practice?
Higher than yours is now, most likely. Rather than chase a benchmark, measure your own rate by hour and target the worst windows — that is where the recoverable revenue is concentrated.
Does an answering service fix this?
Only if it books. A service that takes messages moves the problem rather than solving it, because the patient still has not got an appointment.
