20-35% of incoming calls. That's how many a typical dental practice misses during business hours. After 5:30pm, the miss rate is 100% unless you've got coverage.
Each missed call from a new patient enquiry is $2,000-$5,000 in lifetime value. That's not a made-up number. A new patient who stays for 5 years at 2 visits a year averaging $400-$500 per visit is $4,000-$5,000. Some will need crowns, implants, ortho referrals. The downstream value is real.
Ten missed new patient calls a month at $3,000 average is $30,000 walking out the door. Every month. You'll never see it in your P&L because there's no line item for "revenue from calls nobody answered."
Why it happens
Your receptionist is checking someone in. The phone rings. They can't answer because they're processing a payment and the patient in front of them is waiting. So it rings out.
Or they're on another call already. Or at lunch. Or it's 5:15pm and they're closing up. Or a Wednesday afternoon when the practice runs a half-day and nobody's there after 1pm.
In a solo practice with one front desk person, there's zero redundancy. When that person is occupied with anything, the phone is unattended. And in a dental practice, the receptionist is always doing something. Checking in, checking out, processing payments, filing, answering questions from patients in the waiting room. The phone is their fifth priority on a good day.
What happens when a call goes unanswered
Up to 35% of callers won't leave a voicemail. They'll call the next practice in their search results. For new patient enquiries the window is even tighter. A patient searching "dentist near me" has 4-5 options open in tabs. They're calling in sequence. The first practice that picks up wins.
Your phone goes to voicemail. The practice 2km away answers on the second ring. You've lost that patient permanently. And here's the part that makes it invisible: you never knew they called. No record. No metric. Just an absence you can't measure.
Existing patient calls matter too. A patient calling to book a hygiene visit ($400) who doesn't get through might try again. Or they might not, and they slowly become a lapsed patient. Each of those is $300-$600 per missed recall visit, compounding every 6 months they don't come back.
Do the maths on yours
Average incoming calls per day. Multiply by your miss rate (25% is a conservative midpoint). Separate new patient enquiries from existing patient calls.
For a practice receiving 30 calls a day:
30 calls x 25% miss rate = 7.5 missed calls per day. Say 2 of those are new patient enquiries. That's 40 missed new patient calls per month.
At $3,000 average lifetime value: $120,000 per year in potential revenue that never materialised. Even if only half of those callers would have booked, that's $60,000. From one problem. That nobody's tracking.
The existing patient calls matter too. 5.5 missed existing patient calls per day x $400 average visit value = $2,200 per day in immediate booking revenue at risk. Not all of them will be lost, many will call back. But some won't. And those become lapsed patients.
Three ways to fix it
Hire another receptionist: $40,000-$50,000 a year. Covers business hours only. Doesn't help after 5:30pm or on your half-day. And you now have two people to manage, roster, and cover for when one is sick.
Traditional answering service: $500-$2,000 a month. The quality is usually poor. The person answering doesn't know your practice, can't book into your schedule, and sounds like a call centre. Patients notice.
AI receptionist: Handles missed call callbacks, after-hours enquiries, and overflow during busy periods. Knows your schedule. Can qualify new patient enquiries and book them in. Sends confirmation SMS. Runs 24/7.
The AI Receptionist through Siace Partners sits in the Performance tier. It's layered on after bookkeeping and reporting, so by the time it's active you already have visibility into call patterns and revenue data.

Frequently asked questions
How many calls does a dental practice miss?
Research suggests 20-35% of incoming calls during business hours, due to the receptionist being occupied with patients, on another call, or away from the desk. After-hours calls go entirely unanswered in most practices.
How much does a missed call cost a dental practice?
A missed new patient enquiry represents $2,000-$5,000 in lifetime value based on average visit frequency and spend over 5 years. Existing patient calls represent $200-$600 per visit in immediate booking revenue.
How can a dental practice stop missing calls?
Three options: hire additional reception staff ($40,000-$50,000/year), use a traditional answering service ($500-$2,000/month), or deploy an AI receptionist that handles overflow, after-hours, and missed call callbacks automatically.
