How a Bordeaux Dental Practice Reduces No-Shows by 40% with AI Reminders

Case study: a Bordeaux dental practice that reduced missed appointments by 40% using personalized AI reminders.

The Hidden Cost of Missed Appointments

Dr. Sophie Mercier, dentist in Bordeaux Chartrons, had a problem costing 35,000 euros per year: no-shows. 5 to 8 missed or last-minute cancelled appointments weekly.

Gartner (2024): medical and dental practices deploying multi-channel AI reminders reduce no-shows by 35-45% and increase occupancy by 22%.

Step 1: Risk scoring - GPT-4o analyzes each patient's history to calculate no-show risk score (previous no-shows, appointment time, care urgency).

Step 2: Personalized reminder sequence:

  • Low risk: J-3 email + J-1 SMS with confirmation request
  • High risk: J-7 email + J-3 SMS + J-1 SMS + J-0 morning WhatsApp

Step 3: Automatic waiting list management: when a patient cancels, AI identifies 5 best-fit waiting list patients and sends them an SMS. First to respond gets the slot. 74% of cancelled slots are filled.

Step 4: Upcoming appointment confirmation: weekly confirmations sent to all patients with appointments in 7 days. Secretary now calls only 3-5 patients/day instead of 25.

Dr. Mercier's Results After 6 Months

  • No-shows/week: 6.2 -> 3.7 (-40%)
  • Occupancy rate: 71% -> 88%
  • Cancelled slots filled: 25% -> 74%
  • Financial loss from no-shows: 35,000€ -> 12,000€/year
  • Secretary reminder time: 2h/day -> 15min/day

McKinsey (2024): practices automating reminders recover an average of 28,000 euros annual revenue. Bpifrance (2025): 63% of French dental practices that deployed AI reminders recoup the investment in under 2 months.
