“Canine teeth (and incisors) are frequently damaged from random trauma (HBC, falls, etc.). The most commonly fractured tooth in dogs is the maxillary 4th premolar. This tooth is most often fractured due to chewing trauma. Bones (ANY actual bone), non-flexible nylon bones, antlers, hooves, and, a recent addition to the bad chew toy list, yak’s milk. These products are often advertised as long-lasting. Unfortunately, because they don’t break down, the teeth used to chew them, usually the maxillary 4th premolar, does fracture. Since these fractures occur from chewing trauma, rather than random trauma, dogs are likely to fracture both maxillary 4th premolars. A common fracture of the maxillary 4th premolar can be a “slab fracture, “fracturing a significant portion of the buccal surface of the tooth and often extending below the gum line to the root structure.
