NovaDent

Project Overview

NovaDent is an AI voice assistant built for dental practices that were losing patients to unanswered calls. It picks up every call, in any language, 24/7 — answers questions about treatments and pricing, books an appointment directly into the clinic’s calendar, and sends the patient an SMS/WhatsApp confirmation. The front desk only sees the outcome.

Client Challenges

• The practice missed up to a third of its calls — every unanswered call was a patient booking elsewhere.
• Staff spent their mornings replaying voicemails and phoning patients back, instead of caring for patients in the chair.
• Two assistants answered the same questions differently (emergency procedures, pricing, insurance), which created doubt at exactly the wrong moment.

Our Solution

• A voice callbot that answers instantly, recognizes intent from natural conversation, and handles the full booking flow — from “I have a toothache” to a confirmed slot with the right practitioner.
• Native speech-to-text and text-to-speech so the call sounds human, with no robotic pauses.
• Deep calendar integration: availability is read live, so the assistant never proposes a slot that doesn’t exist, and never double-books.
• Automated SMS/WhatsApp confirmations and reminders after each booking, reducing no-shows.

Key Features

• Zero missed calls: every call is answered in under a second, day and night.
• Guided booking: the callbot proposes real available slots (practitioner, date, time) and confirms in one flow.
• Emergency detection: urgent cases are routed to the practice with priority.
• Multi-channel follow-up: confirmation and 24h reminders sent by SMS and WhatsApp automatically.
• Call analytics: the practice sees answered-call rate, booked-appointments, no-shows and peak hours in one dashboard.

“We no longer lose patients because we were on another line. The callbot books, confirms and reminds — we just care for patients.” — Practice manager, NovaDent
