Guinea pig dental disease is prevalent and largely preventable through dietary management that ensures continuous tooth wear throughout life.
Guinea pig dental welfare is almost entirely preventable through appropriate diet from the beginning of a guinea pig's life. The fundamental principle is simple: hay provides the necessary lateral grinding motion that wears teeth appropriately; pellets and vegetables do not provide adequate tooth wear. The welfare tragedy is that dental disease is prevalent because pet industry marketing and cultural norms have created pellet-dominated feeding patterns that fail guinea pig dental health. Correcting this dietary misconception prevents enormous welfare harm - dental disease causes chronic pain that may be expressed only as subtle weight loss and reduced activity.
