In this webinar, veterinarian Sebastián Greco offers a critical perspective on a widespread practice in equine production: routine tooth filing, often performed with inadequate tools and by untrained individuals. Throughout the session, Sebastián invites us to analyze common mistakes, the impact of intervening without sufficient information, and the principles that should guide responsible dental care. He will also share appropriate criteria and procedures for understanding and treating the horse's mouth from a clinical, functional, and science-based perspective.
