You've decided your dental practice needs an answering service or AI receptionist. You've Googled around. Two names keep coming up: Smith.ai — the established player, founded 2015, big enterprise reputation — and Apex Tools AI — newer, bilingual-first, dental-and-med-spa specific.
You're a 2-doctor practice. You'd like one decision, not three months of comparison. This article exists to make that one decision easier.

What Smith.ai does well
Let's be fair to a good company. Smith.ai isn't just any answering service — they have invested heavily in their tech stack, their agent training is real, and their integrations are decent. If you're a law firm or an accountant looking for warm message-taking, they're a defensible choice.
Specifically, Smith.ai's strengths:
- Real humans answering the phone — for some practices, this still matters. There are patients who can immediately tell they're talking to AI and don't like it.
- Lower entry price for low call volume — $325/month for 20 calls is fine if you're getting 4-5 calls per week.
- Established brand — they've been in market since 2015, have decent reviews, and won't disappear next quarter.
- No setup fee — you can be live by tomorrow.
If your practice gets 20 or fewer inbound calls per month and you just need someone professional to take a message, Smith.ai is fine.
Where Smith.ai falls down for dental practices
The problems start when you scale up call volume or have specific dental needs.
1. Per-call pricing punishes growth. Smith.ai's $325/mo base includes 20 calls. After that, you pay $7-$15 per call (the rate depends on plan tier). A practice getting 100 inbound calls per month pays $325 + (80 × $9) = $1,045/month. A 200-call/month practice pays around $1,945. You're punished for being busy.
2. Bilingual is an upcharge. Smith.ai offers Spanish-speaking agents, but at a premium tier. The base plan is English-only. If 30% of your callers prefer Spanish (typical in any major metro), you're either paying for the premium tier or losing those callers.
3. They take messages; they don't aggressively book. Smith.ai's default behavior is to take detailed messages and route them to you. Booking directly into your calendar is available but limited to specific integrations and requires extra setup. Most practices using Smith.ai find their staff is still calling patients back to confirm appointments — which defeats much of the point.
4. Concurrent call cap. Because Smith.ai uses human agents, they have a finite pool. During peak hours, second concurrent calls may queue or roll to voicemail. For practices with a Google Ads campaign driving spike traffic, this matters.
5. Healthcare specificity is shallow. Smith.ai serves law, accounting, real estate, healthcare, and many other verticals. Their agents aren't specifically trained on dental terminology, insurance workflows, or the urgent-vs-routine triage that matters for a dental office. They're generalists.
Where Apex Tools AI is stronger
Apex Tools AI is purpose-built for dental practices and med spas. The narrower focus is the point.
1. Flat-rate, unlimited calls. $400/month covers unlimited inbound calls. Whether you do 50 calls or 500, the price is the same. For a 2-doctor practice doing 150+ calls/month, this is dramatically cheaper than per-call pricing.
2. Bilingual is the default, not an upcharge. EN/ES auto-detection is built in. The AI listens to the first caller utterance and locks the language for the rest of the call. Voice quality in both languages is native (ElevenLabs multilingual). No premium tier.
3. Books directly into your real calendar. Google Calendar, NexHealth, Calendly are direct integrations. Open Dental, Dentrix, Eaglesoft work through NexHealth or via calendar sync. The AI doesn't take a message and hand it to you to handle — it books the appointment live, while the caller is still on the line.
4. Unlimited concurrent calls. Five patients calling simultaneously? AI handles all five at once. No queue, no rollover to voicemail.
5. Dental-specific intelligence. The AI knows the difference between "I have a tooth that's bleeding" (urgent — SMS the practice owner now) and "I need a cleaning" (route to next available slot). It knows how to read back a phone number in groups of 3-3-4 with confirmation. It knows when a patient says "I have insurance through Blue Cross" to log that into the appointment notes.
6. Urgent-call SMS alerts. When a caller flags as urgent (pain, bleeding, emergency, VIP), the practice owner gets an instant SMS with the caller's name, phone, and what they said. You call back personally within minutes. That patient is yours for life.
Where Apex Tools AI is weaker (the honest version)
Fair comparisons cut both ways. Apex Tools AI is a newer product:
1. Newer brand. Apex Tools AI launched in 2026. Smith.ai has been around since 2015. If you absolutely need a 10-year track record before you'll consider a vendor, Smith.ai wins.
2. $2,500 setup fee. Smith.ai has no setup fee. Apex charges $2,500 (or $1,500 for the first 50 Founding Client practices). The setup covers building your custom AI — practice hours, services, providers, insurance accepted, cancellation policy — and gets you to a live, tested deployment in 5 days. Smith.ai gets you live the same day with a generic message-taking flow.
3. It's AI, not humans. Some practice owners and some patients have a strong "I want to talk to a real person" preference. Apex Tools AI sounds human (call (954) 475-6922 to verify), but it is AI. If you sell that philosophically, Smith.ai wins.
4. Smaller enterprise feature set. Smith.ai has things like outbound calling, CRM integrations across 50+ platforms, workflow automation, lead qualification scripts that work across verticals. Apex Tools AI is narrower — phone receptionist + website chatbot for healthcare, period.
The actual math for a 2-doctor practice
A typical 2-doctor general dentistry practice handles 50-70 inbound calls per day, or roughly 1,500 per month. Let's run both options:
Smith.ai:
- Base plan with 100 calls included: $600/month
- Overage (1,400 calls × $9): $12,600/month
- Bilingual upcharge: +$200-$400/month
- Total: $13,200-$13,400/month
That's obviously absurd — no 2-doctor practice would actually pay that. The realistic Smith.ai usage pattern is: only use it for after-hours and lunch overflow (~20% of total calls = 300/month). That's:
- Base $325/mo + (280 × $9) = $2,845/month for partial coverage
- Bilingual upcharge: +$200-$400/month
- Total: ~$3,200/month for 20% coverage
Apex Tools AI:
- $2,500 one-time setup (or $1,500 Founding)
- $400/month, unlimited calls, all languages, 24/7
- Total: $400/month after setup
The setup fee pays itself off in month one against the Smith.ai cost, and then ongoing it's roughly 12-13 percent of Smith.ai's price for full coverage instead of partial coverage.
When you should still pick Smith.ai
- You're a non-healthcare business (law, accounting, real estate)
- You need outbound calling and lead-qualification across many use cases
- You have <20 inbound calls per month
- You philosophically can't have AI talk to your patients
- You need to be live tomorrow, no exceptions
When Apex Tools AI is the obvious choice
- You're a dental practice or med spa
- You get 50+ inbound calls per month (where flat pricing dominates)
- A meaningful share of your patients prefer Spanish
- You want appointments booked directly into your real calendar, not messages routed to you
- You want urgent callers escalated to your cell phone within seconds
- You're willing to do a 5-day setup for a deployment built specifically for your practice
Easiest way to decide
For Apex Tools AI: call (954) 475-6922 right now. Talk to the AI like a real patient. Try "I'd like to make an appointment" in English, then try "Hola, quiero una cita" in Spanish. The whole evaluation takes 90 seconds. If it sounds like something you'd want answering your patients' calls, see the pricing.
For Smith.ai: visit smith.ai, book a demo, evaluate over 1-2 weeks.
If you're a 2-doctor dental practice in a bilingual market, the math here is going to favor Apex Tools AI by a wide margin. If you're a generalist business not in healthcare, Smith.ai is the safer bet.
There's no universally right answer — but for the specific case of "small dental practice with bilingual patients," the case for Apex Tools AI is concrete:
- 8-12x cheaper monthly at typical call volumes
- Bilingual included, not an upcharge
- Books directly, doesn't just take messages
- 5-day setup gives you a custom-trained deployment, not a generic flow
