What a missed call actually costs a full-arch practice

A missed call leaves no evidence in any report, which is why it never gets fixed. Here is how to put a real number on it, and where the calls are going.

The short version

  • A missed call is the only leak in a full-arch practice that leaves no evidence behind, so it survives every monthly review.
  • Size it before you buy anything. Chain four numbers you mostly already have, and the figure will be larger than the fix.
  • Missed calls cluster in predictable windows. After hours is usually the biggest share and the least covered.
  • Speed to lead is the worse number, because a slow callback never shows up in the phone log at all.
  • Put answer rate and time-to-first-conversation on the same report as production, or the leak stays invisible.

Every other leak in a full-arch practice leaves evidence. A no-show leaves an empty surgical slot on the schedule. A lost case leaves a treatment plan nobody signed. A missed call leaves nothing.

That is the whole reason it goes unfixed. There is no row for it in any report, no line on the dashboard, no moment in the monthly meeting where someone says the number out loud. The practice’s own systems are structurally unable to notice.

So the first job is not buying a dental answering service. It is building the number, because nobody approves spend against a problem they cannot size.

Build the number before you buy anything

Four inputs, and three of them are already sitting in systems you own.

Missed inbound calls per month. Your phone system has this. Not just calls abandoned in a queue. You want unanswered, plus voicemails never called back, plus everything that rang out after hours. Most VOIP dashboards will export it by hour. If yours cannot produce this at all, that is its own finding.

The share of those that were new-patient enquiries. This one you have to sample. Take a single week, check caller ID against your patient list, and split new from existing. The split matters because existing patients call back and new ones call the next practice on their list.

Your close rate on seated consults. Cases started divided by consults seated, across the last quarter.

Your average case value. Full-arch sits somewhere in the $20k to $45k band for most practices.

Now chain them, and watch what happens to a plausible set of numbers. A practice missing 40 calls a month, a third of them new enquiries, gives you about 13. Assume half of those would have booked if someone had picked up, so 6 or 7 consults. At a 30% close rate against a $30,000 case, that is roughly two cases, or somewhere near $60,000 of production that never entered the building.

Those figures are an illustration of the arithmetic, not a benchmark to hold yourself against. Run it on your own four numbers and you will land somewhere else. The point is that you will land somewhere, and the number will almost certainly be larger than the cost of fixing it. That is the conversation that has been missing.

The calls are not going missing at random

Once you have a total, pull the same log broken out by hour and by weekday. The shape is consistent across practices, and it tells you which fix you actually need.

Missed calls cluster in four windows: the lunch hour, the last ninety minutes of the day, Friday afternoon, and everything outside opening hours. The first three are a staffing problem. The fourth is structural, and it is usually the largest.

The after-hours share tends to be the one that surprises owners. A lot of full-arch research happens at night, because someone lay awake thinking about their teeth and picked up a phone. They are not going to set a reminder to call you at ten the next morning. They will work down a list in one sitting, and the practice that answers is the practice that gets the consult.

Speed to lead is the second number, and it is worse

A missed call at least announces itself in the log. A slow callback does not.

Instrument it directly: timestamp when the enquiry arrives, timestamp on the first genuine two-way conversation. Not the first outbound attempt. The first actual conversation. Then take the median across a month, and take the 90th percentile too, because the tail is where the damage sits.

Practices measuring this for the first time usually find a median in hours rather than minutes, and a meaningful share of enquiries that never reached a conversation at all. Those never register as losses anywhere. They sit in the CRM marked “attempted” and quietly age out.

The systems that close the gap

Coverage is the obvious piece and the least interesting one. Whether it is an answering service, an overflow line or a dedicated person, the only requirement is that every enquiry meets a human quickly, including at eight on a Friday evening.

The part that gets skipped is ownership. New-patient enquiries have to belong to someone whose performance is judged on them. When the same person is checking patients in, taking a payment and working a $30,000 enquiry, the enquiry loses. Every time. That is not a training problem and a better script will not touch it.

Then screening. Candidacy, how the patient plans to pay, and whether they genuinely intend to attend. These are the awkward questions, and they matter because a surgical consult slot is scarce. Booking an unqualified patient into one is not a neutral act, it costs you the slot.

Last is the write-back. Whoever takes the call has to leave a structured record: source, what the patient said about their own situation, where they are on financing, and who booked them. Free-text notes are where this dies. Your treatment coordinator should walk into that consult already knowing what was said on the phone three days earlier.

Put it on the report

Add three fields to whatever you already review monthly, sitting next to production rather than buried in an operations appendix:

  • Answer rate on new-patient inbound, split in-hours and after-hours.
  • Median and 90th percentile time from enquiry to first conversation.
  • Count of enquiries that never reached a conversation at all.

That last row does not exist in any practice today, and it is the one that pays for the fix. A leak nobody can see gets debated. A leak with a number next to it gets closed.

Straight answers

Related questions.

How do we know whether a dental answering service is worth it for our size of practice?+
Run the four-number chain in this post on your own phone data before you price anything. If the production you are missing each month is smaller than the monthly cost of coverage, the honest answer is that your constraint is somewhere else, probably consult volume or close rate. Most full-arch practices find the opposite by a wide margin, because a single recovered case covers a year of coverage at full-arch case values.
Will an outside service handle full-arch enquiries properly?+
It depends entirely on whether they screen or just take messages. A service that captures a name and a callback number has moved the delay, not removed it. What you want is someone who can hold a real conversation about candidacy, timeline and how the patient plans to pay, then book into your calendar with that context attached. Ask for recordings before you sign anything.
What is a realistic target for speed to lead?+
Minutes, not hours, and measured to the first genuine two-way conversation rather than the first attempted call. The reason is behavioural rather than technical. Full-arch patients research several practices in one sitting, usually at night, so the practice that reaches them inside that sitting is competing against nobody.
