Dental Malocclusion in Rabbits
Rabbits' teeth grow continuously throughout their lives. When teeth don't align properly (malocclusion), they overgrow, causing severe pain, inability to eat, and secondary infections.

Symptoms & Signs
Difficulty eating or dropping food
Rabbit approaches food eagerly but drops it or chews abnormally.
Preference for soft foods
Rabbit stops eating hay and only wants pellets or greens.
Weight loss
Gradual loss of body mass due to reduced food intake.
Drooling / wet chin
"Slobbers" — fur around the mouth and chin is constantly wet from drool.
Facial swelling
Lumps on the jaw or cheeks from tooth root abscesses.
Behavioral Changes to Watch For
Pets can't tell us what's wrong. These behavioral changes are often the first clues that something is wrong.
🐾 Selective eating
Rabbit picks out soft foods and ignores hay.
What You May Notice:
The hay in your rabbit's enclosure seems untouched, but pellets and treats disappear quickly.
🐾 Grumpiness when face is touched
Rabbit flinches or becomes aggressive when you try to touch their cheeks or chin.
What You May Notice:
Your normally friendly rabbit growls or bites when you pet their head.
Causes & Risk Factors
Causes
- •Congenital malocclusion (genetic — especially in dwarf/lop breeds)
- •Inadequate hay feeding (hay wears down teeth naturally)
- •Trauma causing tooth misalignment
- •Metabolic bone disease affecting tooth quality
- •Age-related changes in tooth growth patterns
Risk Factors
- ⚠Dwarf and lop breeds (shorter skull = higher risk of malocclusion)
- ⚠Low-hay diet
- ⚠Older rabbits
- ⚠Previous dental trauma
How It's Diagnosed
- 1Oral examination (often requires sedation) — check incisors, premolars, and molars
- 2Skull radiographs to assess tooth roots and check for abscesses
- 3CT scan for detailed assessment in complex cases
Treatment Options
Dental Trimming/Burring
Mechanical reduction of overgrown teeth under sedation or anesthesia.
Steps
- 1.Sedation or general anesthesia
- 2.Use of dental burr (not clippers — clippers can crack tooth roots)
- 3.Burr incisors and/or cheek teeth (molar spurs) to proper length and shape
- 4.May need to be repeated every 4-12 weeks for chronic malocclusion
Expected Outcome
Immediate ability to eat normally again after recovery from sedation.
Precautions
- !Clippers should NEVER be used for rabbit teeth
- !Anesthesia carries risk in debilitated rabbits
Dietary Modification
Long-term management through appropriate abrasive foods.
Steps
- 1.Unlimited grass hay — timothy, orchard, or meadow
- 2.Limit pellets (which require less chewing)
- 3.Provide safe wood chews (apple, willow branches)
- 4.Regular weight monitoring to ensure adequate intake
Expected Outcome
Reduced frequency of dental procedures needed.
Precautions
- !Diet alone cannot fix existing severe malocclusion — dental procedures are still needed
Common Medications Used
| Medication | Usage | Important Notes |
|---|---|---|
| Meloxicam (Metacam) | Pain relief before and after dental procedures | Given orally. Helps the rabbit resume eating after dental work. |
Prevention
- ✓Feed unlimited grass hay from the time the rabbit is weaned
- ✓Choose a rabbit from a breeder who screens for dental health
- ✓Provide wooden chew toys and branches
- ✓Annual veterinary dental checks including oral examination
When to See a Veterinarian
- ⚠️Wet chin or drooling
- ⚠️Dropping food while eating
- ⚠️Facial swelling — possible abscess
- ⚠️Not eating (dental pain is a common trigger for GI stasis)
Frequently Asked Questions
Can rabbit teeth be removed?
Prognosis
Good with regular management. Many rabbits require repeat dental burring every 1-3 months. Tooth root abscesses carry a more guarded prognosis.

GI Stasis in Rabbits
The most common and dangerous digestive emergency in rabbits. The gastrointestinal tract slows down or stops completely, leading to painful gas buildup, toxin accumulation, and death if untreated.
severeSnuffles (Pasteurellosis) in Rabbits
A highly contagious bacterial respiratory infection caused primarily by Pasteurella multocida. The "common cold" of rabbits — but much more serious. Can become chronic and spread to other organs.

A common endocrine disorder where the body cannot properly regulate blood sugar. Most cats have Type 2-like diabetes associated with obesity. With proper management, many cats achieve diabetic remission.
moderateFeline Pancreatitis
Inflammation of the pancreas, often occurring alongside intestinal and liver disease (triaditis). Unlike dogs, cats often show vague signs — lethargy and decreased appetite rather than vomiting.
