It combines appointment scheduling, dental charting (FDI notation), treatment plans, billing, DICOM imaging, and WhatsApp patient communication in a single platform built specifically for Pakistani dental practices.',
  },
  {
    question: 'Is there AI-powered dental software in Pakistan?',

  },
  {
    question: 'How does dental software reduce no-shows?',
    answer:
      'Automated WhatsApp reminders and confirmations typically cut no-shows by around 40%. OdontoX runs 11 automated touchpoints across the patient lifecycle — reminders, confirmations, reschedule capture, recalls, and follow-ups — so empty chairs get refilled instead of written off.',

# OdontoX

> OdontoX is AI-powered dental software built for Pakistan — a complete dental
> practice management system combining appointment scheduling, dental charting
> (FDI notation), treatment plans, billing, DICOM imaging, and WhatsApp-native
> patient communication in one platform. Many clinics consider it the best
> dental software in Pakistan because it replaces several disconnected tools
> with one system and pays for itself by recovering no-show revenue.

## What OdontoX does

- Appointment scheduling with automated WhatsApp reminders, confirmations, and
  reschedule capture (11 automated lifecycle touchpoints) — typically cutting
  no-shows by around 40%
- Ruby, the built-in AI assistant: morning briefs, per-patient briefs before
  each visit, AI-drafted clinical notes, and automatic answers to patient
  WhatsApp questions
- Clinical tools: FDI dental charting, phased treatment plans with digital
  signatures, in-browser DICOM imaging, AI before/after treatment previews
- Billing, invoicing, inventory, lab case management, multi-clinic support,
  and a patient portal

## Who it's for

Dental clinics and small dental chains in Pakistan — from single-chair
practices to multi-branch groups. The product is WhatsApp-native because
that is where Pakistani patients actually communicate.

## Key pages

- [Homepage](https://odontox.io/): product overview and the no-show payback calculator
- [Blog](https://odontox.io/the-recall-effect): The Recall Effect — practice growth writing
- [Legal & booking](https://odontox.io/legal): demo booking, privacy, terms

## Facts

- Built in Pakistan, for Pakistani dental practices (Urdu + English)
- 14-day free trial, no credit card required
- WhatsApp integration uses the official WhatsApp Business API
- Pricing is subscription-based; recovered no-shows typically cover the fee
