The Ordre des dentistes du Québec’s March 2025 guide on botulinum toxin A and filling agents established a formal training pathway for Quebec dentists entering aesthetic and therapeutic injectable practice. This article explains what the guide actually requires: a four-level progressive training structure, patient experience thresholds before advancing between levels, the complete clinical pathway every patient encounter must follow, the six conditions for issuing individual orders to nurses, and the dental-office standards required at every practice location. It also clarifies what the guide does not cover, including microneedling, PRP, and thread lifts, which remain under ODQ analysis as of July 2026. Written for Quebec dentists considering or currently practising botulinum toxin A and dermal filler treatments.
