AI receptionists for dental offices: what real practices found
AI receptionists, after-hours answering, booking and call follow-up. 3 case studies so far, each with what it cost, what worked and what didn't.
Short answer
No case on this site shows one "best" AI receptionist for a dental office. The good results reported here, one from a vendor and one from an office, come from AI used only for overflow and after-hours calls. The problems reported include callers who never reached a person and changes the AI confirmed but never made, and a mock emergency call that didn't reach the doctor.
The biggest numbers are vendor claims. Arini reports that Wolfe Dental, a two-office practice in the Portland area with one receptionist per office, went from missing as many as 500 calls a month to about 50. It also reports the AI booked $134,000 in production over eight months. That is treatment put on the schedule, not money collected, and Arini publishes no price. Per Arini, the calls still missed were the AI's transfers to the front desk that nobody picked up.
The most detailed practitioner data comes from an Open Dental office near Los Angeles, where a part-time staff member went through 15 months of call summaries and transcripts. Of the 637 calls where someone wanted something done, the AI completed 263 (41%), and that count includes messages taken. Bookings, reschedules and cancellations actually made on the call came to about 22%. Callers asked for a person 65 times and none got through. The author put the cost at about $300 a month and later built a competing product, so weigh the comparisons with that in mind.
Offices are also trying AI receptionists sold as add-ons by vendors they already pay. An office using Dental Intel's AI receptionist only for overflow and after hours says it has booked a number of patients, including new patients after hours. But Dental Intel's own help docs say it can't transfer an ordinary daytime caller to staff mid-call. A Mango Voice office says patients give Margo clearer details than they give staff, but that Margo can't write back to Open Dental. Mango lists Margo only in its Complete plan, at $449 a month.
Key numbers
- 263 of 637 (41%) Calls the LA-area Open Dental office's AI receptionist completed over 15 months, out of calls where the caller wanted something done. The 263 includes 76 messages taken and 45 information-only calls. Case
- ~22% Share of those 637 calls that ended with a booking, reschedule or cancellation actually made on the call (142 calls; our arithmetic from the author's table). Case
- 0 of 65 Requests to speak to a person that reached one in the LA office's 15-month log, during or after business hours. Case
- 49.5% LA office calls (709 of 1,432) where the caller was silent or hung up at the greeting. The source doesn't say how many were robocalls, wrong numbers or real patients. Case
- ~20% Share of the LA office's failed AI calls that were in Spanish. The author names new-patient name spelling as the top failure, with Spanish names breaking most often. Case
- ~$300/month The LA office's AI receptionist subscription, per the author. About $400 counting staff time on callbacks, and about $168 of subscription per new-patient booking (the author's figures). Case
- Up to 500 to ~50 Missed calls a month at Wolfe Dental's two offices before and after Arini's AI took overflow and after-hours calls. Arini reports this; it has not been checked independently. Case
- $134,000 Production Arini says its AI booked for Wolfe Dental from September 2025 to April 2026. This is booked, not collected, and Arini's headline says $140k. Case
- $449/month Mango Voice's Complete plan, the only plan that includes the Margo AI receptionist. Voice + AI without Margo is $349 and Voice alone is $249. The page doesn't say whether prices are per location. Case
- 1,000 minutes/month Included with Dental Intel's AI receptionist add-on, per its help center. No published price. Dental Intel's cancellation policy says agreements typically run a year and renew automatically unless you cancel at least 30 days ahead, and you still owe the rest of the term. Case
- 3 rings Unanswered rings before a call goes to the AI at the office using Dental Intel's AI receptionist. All calls go to it after hours. Case

AI receptionist for overflow and after-hours calls: Wolfe Dental's results
A two-office practice in the Portland area with one receptionist per office let Arini's AI take overflow and after-hours calls. Arini reports missed calls fell from as many as 500 to about 50 a month and $134k in booked production over eight months, but it gives no price.
AI receptionist audit: LA dental office's 15-month call log shows 41% task completion
A part-time staff member at an Open Dental practice near Los Angeles read every failed call from 15 months of an AI receptionist. It finished 263 of the 637 calls where someone wanted something done, never put a caller through to a person, and had trouble with Spanish and with spelling names. The author later built a competing product, so weigh the comparisons with that in mind.
Dental Intel AI receptionist vs. Mango Voice Margo: what dental offices report
Some offices are trying the AI receptionists that their current phone or practice-platform vendor now sells as an add-on. One office uses Dental Intel's only for overflow and after hours, and it books new patients at night. Another tester couldn't reach the doctor in a mock emergency. A Mango Voice office says Margo gets clearer caller details than staff do, but it can't write back to Open Dental and its calls are hard to track.
Questions dental offices ask
How much does an AI receptionist for a dental office cost?
Two of the three named vendors in these cases publish no price. At the LA-area Open Dental office, the author puts the subscription at about $300 a month, or about $400 counting staff time spent returning the AI's messages. Mango Voice includes Margo only in its Complete plan, at $449 a month. Dental Intel publishes no price for its add-on, which includes 1,000 minutes a month. Its agreements typically run a year and renew automatically unless you cancel at least 30 days ahead. Arini shows no public pricing; its pricing page returned a 404 on 2026-10-20.
Can an AI dental receptionist book appointments directly in Open Dental?
Not always, so ask exactly what "books" means. At the LA-area Open Dental office, the AI booked 70 appointments in 15 months. But in 9% of failed calls it said it would make a change, couldn't, and only took a message. A Mango Voice office on Open Dental says Margo has no write-back and can't act on its notes, while Mango's page says Margo creates a callback task in the practice-management system. Dental Intel lets you choose, for each appointment type, whether the AI creates the appointment or only requests it for staff approval. Its scheduling is in beta and needs Dental Intel Online Scheduling.
What do dental offices on Reddit say goes wrong with AI receptionists?
In the LA office's 15-month call log, posted on r/Dentists, hang-ups mid-call were the biggest failure (40% of 378 failed calls). None of 65 requests for a person reached one, and family members booking for elderly patients confused the AI. In an r/Dentistry thread where vendors weren't named, one office fired its vendor after the AI booked patients on dates, at times and at locations that weren't open. Another dentist said it booked several crowns at the same time as emergencies and denture adjustments, then scrapped it, and says the schedule was disrupted for about two months. On r/Dentistry, a dental professional using Adit reported that a whitening promotion brought 10 calls through the AI and zero appointments, and the office went back to a human answering service.
Should an AI receptionist replace the front desk or just take overflow calls?
None of these cases describes an AI replacing the front desk; each describes overflow and after-hours use. At Wolfe Dental, per Arini, the AI took overflow during business hours and all calls after hours, covering calls that were going to voicemail. The office happy with Dental Intel's AI has staff answer first and sends calls to the AI after 3 unanswered rings or when the office is closed. At the LA-area office, about half the AI's calls were daytime overflow and half came in evenings, weekends and holidays.
How do you measure if an AI receptionist is working for your dental office?
Track the completion rate, not the answer rate. The LA-area office counted 41% of the 637 calls where the caller wanted something done as completed, but that included messages taken. Changes actually made to the schedule on the call came to about 22%. Ask how the vendor counts AI-answered calls: a Mango Voice office says Mango doesn't count Margo-answered calls as missed, but the office does. Before go-live, record your missed calls a month and your answer rate. Then ask the vendor in writing for the monthly price, appointments booked, appointments kept and production collected, not only calls handled (Wolfe Dental case).
Can an AI receptionist handle Spanish-speaking dental patients?
In the only case with data, it had trouble. At the LA-area office, which has a large Spanish-speaking patient base, about 20% of failed calls were in Spanish. The author names new-patient name spelling as the top failure, with Spanish names breaking most often. If many of your patients speak Spanish, test whole calls in Spanish, including spelling a new patient's name, before you sign.
Before you buy: a checklist
- Count your missed calls a month and your answer rate before any trial, so you have a baseline to compare against (Wolfe Dental case).
- Start with overflow and after-hours calls only. One office has staff answer first and sends calls to the AI after 3 unanswered rings or when closed (Dental Intel vs. Margo case).
- Write the AI's call rules before the vendor demo: new-patient intake, emergency red flags, appointment types and lengths, approved insurance answers, and what it must never do. Use the prompt "Write your AI receptionist's call rules before the vendor demo" (Wolfe Dental case).
- Get in writing: monthly price, whether it's per location, any minute cap, contract length, auto-renewal and cancellation notice. Dental Intel says its agreements typically run a year and need at least 30 days' notice to stop renewal (Dental Intel vs. Margo case).
- Ask for the vendor's completion rate and how it defines "completed." Does a message count? (LA call-log audit)
- Ask exactly what "books appointments" means in your practice-management system: does it create the appointment, request it for staff approval, or only leave a note or task? Check your PMS right after each test call (Dental Intel vs. Margo case, LA call-log audit).
- Run our 10-call test script, built from the LA author's checks, on a trial line once during business hours and once after hours. It covers asking for a person, moving an appointment, spelling a hard name, booking for a family member and reporting a swollen face (LA call-log audit).
- Test an after-hours emergency call yourself before go-live and confirm it reaches whoever is on call. Test again after any vendor update (Dental Intel vs. Margo case).
- If many patients speak Spanish, run whole test calls in Spanish, including spelling a new patient's name (LA call-log audit).
- Ask how AI-answered calls are reported. Are they counted separately from staff-answered and unanswered calls? Is there a dashboard, and where are the recordings and summaries kept? (Dental Intel vs. Margo case)
- Name who owns the AI's transfers and messages, and set a callback deadline. At Wolfe Dental, Arini says the calls still missed were transfers nobody picked up (Wolfe Dental case).
- Turn on only a few appointment types first. Dental Intel suggests new-patient exams and hygiene for returning patients (Dental Intel vs. Margo case).
- Don't count on sending phone callers to your website to book. At the LA office, being redirected there was one of the moments callers hung up (LA call-log audit).
- After the trial, read the full transcript of every incomplete call, not just the summary email, and sort the failures by cause (LA call-log audit).
- Tell patients when the AI answers and what it can do. The Dental Intel office says this removed almost all pushback (Dental Intel vs. Margo case).
