A mid-size dental practice was losing an estimated $15,000/month in missed appointment bookings due to after-hours calls going to voicemail. Their front desk staff was also overwhelmed during peak hours, leading to long hold times and abandoned calls. We deployed a conversational AI voice agent that handles the entire inbound call flow — greeting callers naturally, understanding their intent, qualifying new patient leads, checking appointment availability, and booking directly into the practice management system. The AI handles insurance questions, provides office hours and directions, and seamlessly transfers to a human when the situation requires it.
The practice needed an AI that could handle the nuance of medical scheduling — understanding urgency levels, insurance verification requirements, provider preferences, and complex scheduling rules like procedure-specific time blocks. The system also needed to sound natural enough that callers wouldn't hang up, and had to integrate with their existing practice management software that had no public API.
We built a custom voice pipeline using Twilio for telephony, a fine-tuned LLM for conversation management, and ElevenLabs for natural-sounding text-to-speech. The system connects to the practice management software via a custom API bridge we built to read and write appointment data. We trained the model on hundreds of real call transcripts to understand dental-specific terminology and patient intent patterns. The AI uses a decision tree backed by LLM reasoning to determine when to book, when to ask clarifying questions, and when to transfer to staff.

AI Agent: Good afternoon, thank you for calling. How can I help you today?
Caller: Hi, I'd like to schedule an appointment for next Tuesday if possible.
AI Agent: Of course! I have availability on Tuesday. Would you prefer morning or afternoon?
Caller: Morning would be great, ideally around 10.
AI Agent: I have 10:00 AM and 10:30 AM available on Tuesday. Which works better for you?
Caller: 10 AM is perfect.
AI Agent: Excellent! I've booked you for Tuesday at 10:00 AM. Can I get your name and a phone number for the confirmation?
Caller: Sure, it's Sarah Mitchell, 555-0142.
AI Agent: Got it, Sarah. You're confirmed for Tuesday, April 29th at 10:00 AM. You'll receive a text confirmation shortly. Is there anything specific you'd like to discuss during the appointment?
Caller: No, that covers it. Thanks!
AI Agent: You're welcome, Sarah! Have a great day. Goodbye.
We went from missing 40% of our calls to capturing virtually every lead. The AI sounds so natural that most callers don't even realize they're talking to a machine.
If it exists, AI can improve it. Let's build something great together.
