How to Measure Missed Calls at Your Dental Practice

Most practices are measuring the wrong thing

Ask a practice owner how many calls they miss and you'll usually get a shrug and a guess. Ask their office manager and you'll often get a different guess.

The reason isn't carelessness. It's that the number isn't sitting anywhere obvious. Most phone systems show you answered calls clearly and bury the unanswered ones, and the calls that never even reached your line — because the caller hung up during a busy signal or a full voicemail box — often don't appear at all.

Industry benchmarks published in Dental Economics put unanswered calls at 30–38% during business hours. A 2026 Peerlogic case study that tracked 4,280 inbound calls across 26 practices measured 38% unanswered. Those are averages. Your practice might be well below them, or considerably above. You won't know until you look.

Why the number is usually worse than the guess

Three things make missed calls hard to see:

Voicemail hides the volume. Only around 14% of new patients leave a voicemail when they can't get through. The rest hang up and call the next practice on their list. If you're judging your missed-call rate by how many voicemails you get, you're seeing a fraction of the real number.

After-hours calls are invisible. Roughly 45% of calls to dental practices arrive outside 9-to-5. If those roll to a machine and nobody logs them, they vanish from your view entirely.

Busy-line calls may never register. When your front desk is already on a call and a second one comes in, what happens depends on your phone system. Some log it. Some don't. If yours doesn't, that call is invisible.

How to pull the data — by phone system

The report you want is usually called a call detail record, call log, or call history. You want at least 30 days, ideally 90.

RingCentral

Admin Portal → Analytics → Performance Reports → Calls. Filter to inbound. Look for the Missed and Abandoned columns.

Ooma Office

Admin panel → Reports → Call Logs. Export to CSV and filter by call result.

Vonage Business

Admin portal → Reports → Call Logs. Filter by direction (inbound) and disposition.

8x8

Analytics → Call Quality and Call Activity reports. Inbound, filtered by unanswered.

Traditional carrier line (AT&T, Verizon, Spectrum)

Landlines typically don't provide call detail records for inbound calls. If you're on a traditional line, you likely can't measure this at all without adding call tracking. That's worth knowing on its own — it means your current visibility is zero.

Any system with call tracking installed

CallRail, CallTrackingMetrics, Peerlogic — these are purpose-built for exactly this. Pull the missed-call report directly.

What to actually count

Once you have the export, sort it into four buckets:

1. Answered — someone picked up
2. Missed / unanswered — rang out, no answer
3. Abandoned — caller hung up before it rang out or while on hold
4. Voicemail — routed to voicemail, whether or not a message was left

Your missed-call rate is buckets 2, 3, and 4 divided by the total.

Counting voicemail as "missed" sometimes causes an argument. Include it. A caller who reaches your voicemail did not reach your practice, and most of them won't leave a message or call back.

The three numbers worth knowing

Overall missed rate. Your headline number. Compare it to the 30–38% industry range.

Missed by time of day. Almost every practice has a lunch hole and a morning-rush hole. Slice your data by hour and the pattern usually jumps out. If 12–1pm is your worst hour, that's a staffing decision, not a technology problem.

Missed after hours vs during hours. These are separate problems with separate fixes. Missing calls at 2pm on a Tuesday means your front desk is over capacity. Missing calls at 7pm means you have no after-hours coverage at all.

What the number means once you have it

Why this matters more for new patients

TrueLark's analysis of 8 million patient conversations found that 58% of missed-call interactions came from new patients, and the large majority of missed calls were booking requests rather than general questions.

That's the part that stings. The calls you're missing skew toward exactly the callers you spent marketing money to attract.

What to do after you measure

Measurement usually points to one of three answers:

A coverage problem. If your misses cluster in a specific window — lunch, Monday mornings — the fix might be scheduling, not software. Stagger breaks. Add a second person during the identified peak.

A capacity problem. If you're missing calls evenly throughout the day with a fully staffed desk, you've hit a real ceiling. A front desk person costs $45,000–$55,000 a year fully loaded, and adding one may not be the cheapest answer.

An after-hours gap. If most misses are outside business hours, no amount of daytime staffing fixes it. You need something that answers when nobody's there.

The right answer depends on which pattern your data actually shows — which is exactly why measuring first matters.

If you want the after-hours gap covered

Aria is an AI receptionist built for dental practices. It answers calls your front desk can't take, books directly into your practice management system, and hands off anything unusual to your team. Most practices run it as a safety net — staff answer first, Aria catches what rings through.
