Rabbit Teeth Problems: Signs of Dental Disease and Why Hay Matters

---

Dental disease is the number one health problem in pet rabbits — and one of the most frequently missed by owners until it has become severe.

How Rabbit Teeth Are Different

Unlike humans, rabbits have open-rooted, continuously growing teeth — both incisors and molars grow throughout their entire lives. In a healthy rabbit eating appropriate amounts of hay, this constant growth is balanced by constant wear. When that balance breaks down, teeth become overgrown or misaligned.

Incisor Malocclusion

The front teeth fail to align properly and do not wear against each other. They overgrow into long, curved spurs that can protrude outside the mouth. Some rabbits are born with a genetic predisposition to this — especially lop breeds and dwarf breeds.

Molar Spurs

The cheek teeth develop sharp points that cut into the tongue or the inside of the cheeks. This is often the more serious problem because it is completely invisible without a dental exam under sedation. Owners frequently have no idea their rabbit has been in pain for months.

Signs of Dental Problems

• Dropping food while eating — picking up food and immediately dropping it
• Preference for soft foods over hay
• Wet or drool-stained chin
• Reduced appetite or refusal to eat
• Weight loss
• Eye discharge — due to pressure on the tear duct from overgrown molar roots
• Facial swelling or abscess in severe cases

Prevention: The Hay Rule

The single most important thing: provide unlimited timothy hay or orchard grass as the foundation of their diet (80–90% of total food intake) (AEMV Pet Care Guides, 2024). Long-strand hay requires extensive chewing, which naturally wears down teeth. Pellets and treats do not provide adequate dental wear.

What to Do

Dental disease in rabbits cannot be treated at home and cannot be fully assessed without sedation. Take your rabbit to an exotic vet for a full dental exam. Treatment may include tooth filing, extraction of severely affected teeth, or treatment of associated abscesses.
