A broken tooth is one of the most painful dental injuries a dog can experience—and one of the most commonly overlooked. Because dogs rarely stop eating or vocalizing in response to dental pain, many fractured teeth go undetected for weeks or months. At West Concord Animal Clinic, Dr. Jennifer Schickler and Dr. Catherine Cole see tooth fractures regularly and want pet owners throughout Concord, Carlisle, Acton, and surrounding communities to understand how to recognize this condition and why treatment is essential.
What Causes Tooth Fractures in Dogs?
Tooth fractures most commonly result from chewing on objects that are harder than the tooth itself. The “knuckle test” is a useful guide: if you wouldn’t want to be hit on the knee with it, it’s probably too hard for your dog’s teeth. Common culprits include:
- Antlers (deer, elk, moose)
- Raw beef bones and marrow bones
- Nylon chew toys
- Ice cubes (especially for aggressive chewers)
- Rocks and stones
- Metal objects or cage bars (in dogs that chew their enclosures)
Trauma—a blow to the face, a car accident, or a fall—can also cause fractures, as can pre-existing dental disease that weakens tooth structure.
Types of Tooth Fractures: Complicated vs. Uncomplicated, and Slab Fractures
Not all tooth fractures are the same, and the severity determines the urgency and type of treatment required:
- Uncomplicated crown fracture: Enamel and dentin are fractured, but the pulp (the sensitive inner tissue containing nerves and blood vessels) is not exposed. These fractures still require evaluation and treatment because exposed dentin is sensitive and porous, allowing bacteria to reach the pulp over time.
- Complicated crown fracture: The pulp is exposed, meaning the tooth’s living tissue is open to the oral environment. This is extremely painful and immediately exposes the tooth to bacterial infection that can spread through the root and into the jaw bone. Prompt treatment is essential.
- Slab fracture: A large piece of the tooth’s side breaks off. The upper fourth premolars (carnassial teeth) are most commonly affected by slab fractures due to their role in crushing hard objects. These fractures often affect the pulp and require immediate attention.
Signs Your Dog May Have a Fractured Tooth
Since dogs often continue eating despite significant dental pain, fractured teeth may be easy to miss. Signs to watch for include:
- Favoring one side of the mouth when chewing
- Dropping food while eating
- Pawing at the face or mouth
- Reluctance to play with chew toys they previously enjoyed
- Swelling on the face, especially below the eye on one side (a sign of a tooth root abscess)
- Drooling, blood-tinged saliva, or mouth odor
- Visible discoloration of a tooth (gray or brown indicates pulp death)
Routine dental examinations at West Concord Animal Clinic allow our veterinarians to identify fractured teeth before they develop into abscesses or bone infections.
Diagnosis and Treatment: Extraction and Root Canal Options
Diagnosing a tooth fracture requires a thorough oral exam under general anesthesia and dental radiographs to assess the tooth root and surrounding bone. Based on findings, treatment typically involves one of two options:
- Extraction: The fractured tooth is surgically removed. This eliminates the source of pain and infection and is often the recommended option, particularly for teeth that are severely compromised.
- Vital pulp therapy or root canal: For appropriate candidates—often younger dogs with recent fractures—root canal treatment can preserve the tooth while eliminating infection. This option requires referral to a veterinary dental specialist in some cases.
Leaving a fractured tooth with pulp exposure untreated is not a safe option. The infection can spread to adjacent teeth and the jaw bone, create painful abscesses, and affect your dog’s overall systemic health.
