The Honest Answer, Up Front
Pricing varies, and any page that quotes you a single magic number is either guessing or hiding fees. What you'll actually pay depends on your call volume, whether you want after-hours coverage, and how the vendor prices — flat monthly, per-minute, or bundled. Rune is priced as a flat month-to-month fee — dental plans start at $497/mo, with final pricing based on your practice's call volume, plus a one-time setup fee we'll confirm on the demo — with no long-term contract, but the more useful thing we can give you is the math to figure out whether any of this pays off for a practice your size.
Here's the one sentence that matters more than the price tag: an AI receptionist isn't an expense you weigh against zero — it's an expense you weigh against the patients currently leaking out of your unanswered calls. Get that framing right and the cost question mostly answers itself.
The Three Ways AI Receptionists (and Their Alternatives) Are Priced
There are really three models on the table when a practice decides how to answer its phones. They price completely differently, so comparing them by sticker alone is like comparing a car payment to a taxi fare — same destination, very different math.
1. Flat monthly AI (how Rune works)
You pay a fixed monthly fee regardless of how many calls come in. Predictable, budgetable, and it rewards you for volume — the busier your phones, the lower your effective cost per call. This is the model that makes sense once you have real inbound volume, because your bill doesn't spike on your busiest month. Rune uses this model: dental plans start at $497/mo, with final pricing set by your call volume, plus a one-time setup fee we confirm on the demo once we've scoped your call flows. That's the whole structure — a flat monthly plus a single upfront setup, no per-minute meter hiding underneath.
2. Per-minute answering service
The old-school live answering services (and some AI vendors) bill by the minute or by the call. Cheap-looking on a slow month, brutal on a busy one. A single chatty new-patient call can run several minutes, and a marketing push that lights up your phones sends the bill straight up with it. The "cheapest AI receptionist" is almost always one of these — cheap until you actually use it. For the full head-to-head, see answering service vs. AI receptionist.
3. A human front-desk salary
The alternative most owners default to: hire a person. Fully loaded — wage, payroll taxes, benefits, training, and turnover — a front-desk hire runs roughly $45,000–$70,000 a year, or about $3,750–$5,800 a month. That buys you warmth, judgment, and in-person coverage no AI matches — but only about 40 hours a week, business hours only. We compare this option in depth in AI receptionist vs. hiring a front desk.
The comparison
| Flat Monthly AI (Rune) | Per-Minute Answering Service | Human Front Desk | |
|---|---|---|---|
| How you're billed | Fixed monthly fee — dental plans start at $497/mo | Per minute or per call | Salary + benefits |
| Monthly cost | Predictable, flat | Swings with call volume | ~$3,750–$5,800 fully loaded |
| Busy month | Same bill | Bill spikes | Same salary (plus overtime) |
| Hours covered | 24/7/365 | Usually 24/7 | ~40 hrs/week, business hours |
| After-hours calls | Answered and booked live | Answered, often at premium rates | Voicemail |
| Books appointments | Yes, in real time | Often just takes a message | Yes, with human judgment |
| Honest by design | Never fakes a confirmation | Varies | Human judgment |
| Setup time | 7–14 day deployment | Days | Weeks to months |
| Contract | Month-to-month, no lock-in | Varies | Employment |
The honest takeaway: flat AI wins on predictability and after-hours coverage, per-minute services punish your busy months, and a human still wins on the in-person, relationship, and judgment work. For most practices the smartest setup is a human at the desk with Rune backing them up — but let's prove that with your own numbers.
The Break-Even Math (Run This on Your Own Numbers)
Forget the sticker price for a minute. The only question that matters is: how many patients does this need to recover before it pays for itself? Here's the whole framework in three inputs. Grab a napkin.
Step 1 — How many calls are you missing?
Count the inbound calls that go to voicemail or ring out in a typical month — after hours, during lunch, when both lines are busy. Most practices are shocked; the real number is usually far higher than the front desk realizes. Call it missed calls per month.
Step 2 — How many of those would have booked?
Not every missed caller is a new patient, so haircut it. A conservative booking rate is 30–50% — the share of recovered calls that would actually turn into a booked appointment.
Step 3 — What's a patient worth?
A new dental patient is worth on the order of $1,200+ in lifetime value once you factor in treatment plans, hygiene recall, and referrals. For an ortho or implant practice, one case can be worth several thousand.
Now multiply:
Missed calls/month × booking rate × patient value = recovered revenue/month
A worked example. Say you miss 40 calls a month, 40% of recovered calls would book, and a patient is worth $1,200:
40 × 0.40 × $1,200 = $19,200 per month in revenue currently walking out the door.
Now compare that to the cost. With Rune's dental plans starting at $497/mo, the break-even is stark:
You only need to recover 2–3 new patients a month for Rune to pay for itself. Everything above that is profit.
That's the entire pitch, and it's just arithmetic. Two or three calls a month that would have hit voicemail. If your practice can't clear that bar, you'll know from your own numbers — and we'll tell you so on the call rather than sell you something you don't need.
Watch Out for Hidden Fees
This is where "cheapest" gets expensive. Before you sign with anyone — Rune included — get these in writing:
- Setup and onboarding fees. Some vendors advertise a low monthly rate, then charge a hefty one-time setup fee to build your call flows. Ask for the all-in first-90-days cost, not just the monthly.
- Per-minute overages on a "flat" plan. Read the fine print. Some "flat" plans include a minute cap and bill overages at painful rates — which quietly turns your flat plan into a per-minute plan on busy months.
- Integration charges. Connecting to your practice management software (Dentrix, Open Dental, Eaglesoft, and the like) sometimes carries a separate fee. Confirm what's included.
- Contract lock-ins and early-termination penalties. A long contract is a bet the vendor makes on your inertia. Rune is month-to-month on purpose — if it isn't working, you leave.
- Charges for after-hours or "premium" hours. With per-minute services, nights and weekends — exactly when you most need coverage — can cost more per minute.
Rune's honest-by-design stance extends to the invoice: flat monthly, no long contract, and we'll walk you through the full cost on the demo. If a vendor won't put their all-in number in writing, that tells you something.
When It's NOT Worth It
We'd rather lose the sale than sell you something that doesn't earn its keep. An AI receptionist is genuinely not worth it if:
- Your call volume is very low. If you get a handful of inbound calls a week and your front desk catches essentially all of them, there's little leaking revenue to recover. The math needs missed calls to work; no leak, no payoff.
- You almost never miss calls and don't want after-hours coverage. If you're fully staffed, rarely go to voicemail, and have no interest in capturing 8 p.m. or weekend callers, the upside shrinks toward zero.
- You can't handle more patients anyway. If your schedule is jammed for months and you're not trying to grow, recovering more new-patient calls just creates a booking backlog. Fix capacity first.
If any of these describe you, keep your money. The break-even framework above will show it plainly — and that's exactly why we hand it over instead of hiding it.
FAQ
How much does an AI dental receptionist cost in 2026?+
It depends on the pricing model and your call volume. Flat monthly AI like Rune is a fixed fee (dental plans start at $497/mo, final pricing based on your call volume, plus a one-time setup fee confirmed on the demo) with no long contract; per-minute answering services bill by usage and swing with volume; a human front desk runs roughly $45K–$70K a year fully loaded. Any vendor quoting one universal price is guessing — ask for their all-in first-90-days cost in writing.
What's the ROI of an AI phone system for a dental office?+
Run the break-even: missed calls per month × booking rate (30–50%) × patient value (~$1,200+). Most practices only need to recover 2–3 new patients a month to cover the cost, and everything above that is profit. Missed calls and after-hours are where the money leaks, so that is where the return comes from.
What's the cheapest AI receptionist — and is cheapest best?+
The cheapest sticker is usually a per-minute service, which looks great on a slow month and punishes you on a busy one. "Cheapest" and "lowest total cost" are rarely the same thing. Judge on all-in cost and whether it actually books appointments and covers after-hours, not on the headline rate.
Are there hidden setup fees with AI receptionists?+
Sometimes — setup fees, integration charges, minute-cap overages on "flat" plans, and after-hours premiums are the common traps. Always ask for the total first-90-days cost. Rune is flat month-to-month and we walk you through the full number on the demo, no surprises on the invoice.
How many patients do I need to break even?+
For most practices, just 2–3 recovered new-patient calls a month cover the cost several times over — because a single new patient is worth ~$1,200+ in lifetime value, and far more for ortho or implants. If your call volume is so low you can't clear that bar, we'll tell you it's not worth it.
Is Rune HIPAA-compliant, and how fast can it go live?+
Yes — Rune is HIPAA-compliant and signs a Business Associate Agreement (BAA). Deployment is typically 7 to 14 days, month-to-month with no long-term contract, so you can test it against your real call volume without a lock-in.
