Summary

This study tested whether sending WhatsApp messages that offer a discount or suggest scheduling a dental check-up on the same day as a medical appointment increases preventive dental care. Over 300,000 adults in Chile who had a medical visit coming up and hadn't seen a dentist in 6 months were included. The goal was to see if these simple behavioral nudges could prevent cavities.
