Cheek tooth spurs are sharp points that form on the molars when a rabbit's continuously growing teeth wear unevenly. Spurs cut into the tongue or cheek, cause pain, drool, and selective eating, and can rapidly progress to GI stasis. Sedated dental burring is the treatment; regrowth is common and most rabbits need repeat dental care every 3 to 12 months (Oglesbee & Lord, 2010, JEPM).

Why Spurs Form
Rabbit cheek teeth (premolars and molars) grow about 2 to 3 millimeters per month for life. They wear against each other during chewing of long-stem fibrous food like hay. When the diet is too low in hay and too high in pellets or sugary treats, teeth wear unevenly, the chewing motion shifts, and sharp lingual (tongue-side) or buccal (cheek-side) points form. Genetics and skull conformation in some breeds — like dwarf rabbits — increase risk.
Signs Owners Notice
Drooling and a wet chin are common early signs. The rabbit may eat slowly, drop pellets out of the mouth, or prefer soft foods over hay. Weight loss appears within weeks. Eye discharge, tearing, or facial swelling appears when upper molar roots are affected (the roots are close to the tear duct). Reduced fecal output is a late but dangerous sign — GI stasis from inadequate intake can kill a rabbit within 24 to 48 hours.
Diagnosis
Conscious oral exam catches some spurs but a sedated dental exam with a proper rodent speculum is needed to find them all. Skull radiographs assess root elongation and any abscess. CT is used in complex cases and at referral centers. Body condition score, fecal pellet count, and a careful history about hay intake guide both diagnosis and follow-up.
Treatment: Sedated Dental Burring
Spurs are removed by burring under sedation or light anesthesia. The vet uses a high-speed dental bur to file the points flush with the crown and to restore proper occlusal angles. Tongue and cheek lacerations are inspected and treated with topical analgesia. Conscious filing is not appropriate — it is stressful, painful, and incomplete. Most rabbits eat the same day after recovery, and the 2019 Benato et al., 2019, JSAP consensus on rabbit pain assessment supports multimodal analgesia for any dental procedure.
Preventing Recurrence
Diet is the single most important prevention. Long-stem grass hay (Timothy, orchard, meadow) should make up 80 to 85 percent of food intake. Pellets are limited to roughly 1/8 to 1/4 cup per 5 pounds of body weight per day, and sugary treats are minimized. Even with perfect diet, many predisposed rabbits need maintenance dentals every 3 to 12 months. Schedule rechecks based on the individual rabbit's regrowth pattern.
When to See a Vet
Call your vet today if:
- Drooling, wet chin, or pawing at the mouth
- Selective eating — soft foods only, refusing hay
- Visible weight loss or reduced grooming
- Eye discharge or tearing in a rabbit with dental history
- Decreased fecal pellet output for more than a few hours
Go to the ER immediately if:
- No fecal pellets for 12 hours or more
- Refusal to eat or drink for more than 12 hours
- Severe lethargy, hunched posture, or grinding teeth (sign of pain)
- Cold ears, cold body, or pale gums
- Sudden jaw swelling or facial deformity

Frequently Asked Questions
Why does my rabbit have cheek tooth spurs?
Continuously growing rabbit teeth wear by grinding fibrous hay. A diet too low in hay or too high in pellets causes uneven wear and sharp points. Genetics, skull shape (especially in dwarf breeds), and prior trauma also contribute. Some rabbits develop spurs even with perfect diets and need regular dental care for life.
How much does rabbit dental care cost?
Exotic vet exam typically runs $80 to $200, skull radiographs add $150 to $400, and sedated dental burring is $300 to $800. Severe cases with extractions are $800 to $2,500. Maintenance dentals every 3 to 12 months add $300 to $800 each. Catching spurs early dramatically reduces cost and complexity.
Can my rabbit live a normal life with cheek tooth spurs?
Yes, with appropriate diet and regular dental care. Many rabbits live a full lifespan with routine maintenance. Owners who skip rechecks or feed pellet-heavy diets eventually face severe dental disease and abscesses, which carry guarded prognoses.
Is conscious tooth filing safe for rabbits?
No. Conscious filing is stressful, painful, and inevitably misses spurs at the back of the mouth. Sedated dental exam and burring with a rodent speculum is the standard of care and is much safer for the rabbit.
Will hay alone fix existing spurs?
No — once spurs have formed, they cut tissue and cause pain regardless of diet. They must be removed by sedated burring. Diet correction is for prevention of new spurs, not treatment of existing ones.
