Dental health is often overlooked yet is among the most important aspects of overall rabbit care. Unlike human teeth, rabbit teeth grow continuously throughout their lives and rely on constant wear from chewing fibrous foods to remain properly aligned and functional. Even minor dental abnormalities can quickly develop into painful conditions that affect eating, grooming, digestion, and quality of life. Understanding how a rabbit’s teeth are designed, recognizing early warning signs of dental disease, and implementing preventative care measures can help ensure your rabbit enjoys a lifetime of healthy chewing and comfortable eating.

Understanding Rabbit Dental Anatomy

Adult rabbits have 28 permanent teeth: six incisors at the front of the mouth and twenty-two cheek teeth, which include premolars and molars farther back. The incisors are the teeth most people notice first, but they are only part of the picture. Rabbits actually have two large upper incisors, two lower incisors, and a second tiny pair of upper incisors tucked behind the main front teeth. These smaller teeth are called “peg teeth” and help guide the lower incisors into proper position when the rabbit bites down.

The incisors are used for grasping, clipping, and cutting vegetation, while the premolars and molars, aka cheek teeth, found farther back in the mouth are responsible for grinding food into tiny particles that can be properly digested. 

What makes rabbit teeth especially remarkable is that they never stop growing. Rabbit teeth are described as “open-rooted”, meaning new tooth material is continuously produced throughout life. In healthy rabbits, the teeth are kept in shape by continual growth and attrition. This constant growth is balanced by the wear of tooth against tooth.

As the rabbit chews coarse grasses, hay, weeds, and fibrous plants, the teeth grind against one another and gradually wear down at approximately the same rate they grow. This natural wear process depends heavily on the rabbit’s diet and chewing behavior. The side-to-side grinding motion used to process hay is particularly important because it keeps the cheek teeth evenly worn and helps maintain proper alignment throughout the mouth.

The Connection Between Dental Health and Digestive Health

A rabbit’s dental health and digestive health are inseparably linked, with problems in one system often leading to complications in the other. Proper digestion begins with effective chewing. Rabbits are hindgut fermenters that rely on a constant intake of coarse, fibrous plant material to keep food moving through the gastrointestinal tract and to support the beneficial microbes in the cecum.

As obligate herbivores, rabbits depend on their teeth to efficiently break down these large quantities of fibrous plant materials before they enter the digestive tract. Proper chewing not only reduces food into smaller, more manageable particles but also stimulates saliva production, which helps lubricate food and supports healthy digestion.

When dental disease develops—whether due to overgrown teeth, malocclusion, molar spurs, abscesses, or tooth root abnormalities—eating can become painful or difficult. Rabbits may begin eating less hay, take longer to finish meals, selectively choose softer foods, or stop eating altogether.

Because the rabbit digestive system relies on a constant intake of fiber to maintain normal gut motility, any reduction in food consumption can quickly slow the movement of the gastrointestinal tract. This slowdown can disrupt the delicate balance of beneficial bacteria within the cecum, leading to digestive upset, abnormal fecal production, gas accumulation, and potentially life-threatening gastrointestinal stasis.

Additionally, inadequate chewing means food enters the digestive system in larger particles, reducing digestive efficiency and nutrient extraction. Poorly chewed food particles are more difficult to process, and the reduction in fiber intake slows gut motility. As intestinal movement decreases, the cecal microbial balance can become disrupted, gas may accumulate, appetite often declines further, and the rabbit becomes increasingly vulnerable to gastrointestinal stasis—a potentially life-threatening condition.

Weight loss, poor body condition, dehydration, and secondary health complications can soon follow. For this reason, a rabbit that develops recurring digestive issues should always be evaluated for underlying dental disease, as the true source of the problem may originate in the mouth rather than the gastrointestinal tract itself. 

Maintaining healthy teeth through a high-fiber diet, regular veterinary examinations, and prompt treatment of dental abnormalities is therefore one of the most important steps in supporting lifelong digestive health.

Common Dental Problems in Rabbits

Malocclusion & ADD

Malocclusion and ADD (acquired dental disease) are common in pet rabbits. Malocclusion occurs when the upper and lower teeth fail to align properly. This can result from genetic predisposition, injury or trauma, poor diet or an underlying disease. ADD is a progressive condition characterized by deterioration in tooth quality, acquired malocclusion and elongation of the tooth roots, usually attributed to lack of dental wear, and often results in abscesses. 

Signs include:

• Overgrown incisors
• Difficulty eating
• Weight loss
• Drooling

Molar Spurs

Molar spurs are sharp points that can develop when cheek teeth do not wear evenly. They may cut the tongue, injure the cheeks and cause significant pain.

Symptoms include:

• Reduced appetite
• Selective eating
• Excessive salivation
• Facial discomfort

Overgrown Incisors

Overgrown front teeth may curve, twist, or protrude from the mouth. Affected rabbits may struggle to pick up food, groom themselves or maintain body weight.

Tooth Root Elongation

Over time, abnormal tooth growth can extend beneath the gumline and into the jaw. This may cause facial swelling, eye problems, tear duct blockage and abscess formation.

Dental Abscesses

Dental abscesses are serious infections that develop around tooth roots. They can be challenging to treat because rabbit pus is thick and caseous rather than liquid.

Signs may include:

• Facial lumps
• Loss of appetite
• Weight loss
• Eye discharge

Treatments for Dental Problems

Clover, the rabbit I rescued in 2021, developed teeth spurs in June of 2025. At the time I had no idea what was wrong with her. She had started drooling and had a dirty face. When our vet examined her, he said she had spurs growing into her cheeks. He immediately performed surgery, filing them down. Recently she started presenting with the same signs. Almost exactly a year to the day, our vet performed surgery again. I asked if this was going to be an annual issue and the answer was yes. Although he over-filed to help inhibit growth for a few months.

Each of these visits cost us $325. According to Nationwide Pet insurance “Veterinary expenses arising out of or related to any treatment for oral health, including but not limited to dental disease, malocclusions and deciduous teeth, where clinical sign(s) (including, but not limited to, tartar, gingivitis, pulp exposure, periodontal disease, or halitosis) were present prior to the effective date of the policy or during the waiting period beginning on the effective date of this policy.” This is something to consider with a rabbit. My advice is to open a savings account and put away as much as possible each month.

Tooth Trimming: Overgrown incisors and molar spurs will need to trimmed while your rabbit is under anesthesia. It is extremely important that you have your exotic vet perform this procedure.

Tooth Removal: Damaged teeth, teeth growing at the wrong angle or root rot abscess teeth may need a complete extraction. This is a complex surgery.

Medication: Because dental problems can be extremely painful, your rabbit may require a medication such as meloxicam.

Feeding: You may need to syringe feed a supplement such a Oxbow Critical Care or Sherwood Pet Recovery or create a mushy feed for your rabbit if it is struggling to eat.

Grooming: Drooling rabbits will need extra attention to keep themselves dry and clean.

Rabbits at Higher Risk for Dental Disease

Certain rabbits may be more prone to dental issues and benefit from more frequent monitoring.

• Dwarf breeds- Netherland Dwarf, Holland lop, Lionhead, Jersey Wooley, Polish
• Brachycephalic (short-faced) breeds-Any mini breed, dwarf breed, lop breed
• Rabbits with congenital jaw abnormalities
• Older rabbits
• Rabbits with previous dental disease

Dwarf and brachycephalic rabbit breeds are significantly more susceptible to dental disease due to the structure and proportions of their skull and jaw. Selective breeding for shortened, rounded faces and compact body types has altered the natural alignment of the teeth and jawbones in many of these rabbits, often leaving insufficient space within the skull for the teeth to grow and function normally. Because rabbit teeth grow continuously throughout life, even slight abnormalities in jaw alignment can lead to serious dental complications over time.

In a naturally proportioned rabbit skull, the upper and lower teeth meet evenly and wear against one another through the repetitive grinding motion created while chewing fibrous plants. In dwarf and brachycephalic rabbits, however, the shortened facial bones can disrupt this alignment. The crowding of teeth within a shortened skull can also affect the roots beneath the gumline. In many brachycephalic rabbits, the cheek teeth are packed into a smaller space than nature originally intended, which can lead to abnormal pressure within the jaw. Over time, the tooth roots may elongate or shift into surrounding structures of the skull and face. This can result in tear duct blockage, chronic eye discharge, facial swelling, jaw abscesses, and even bone deformities.

While some rabbits may be genetically predisposed to dental problems, providing a species-appropriate diet, encouraging natural chewing behaviors, maintaining regular veterinary care, and staying vigilant for subtle signs of discomfort can dramatically reduce the risk of dental disease.

Signs To Watch For

Rabbits hide pain remarkably well which often makes it hard to decipher if anything is wrong. This is where taking the time to really know your rabbit is so important.

• Reduced appetite
• Eating more slowly than usual
• Preference for soft foods
• Dropping food while chewing
• Weight loss
• Excessive drooling
• Wet chin or dewlap
• Dirty mouth
• Nasal Discharge
• Eye discharge
• Reduced grooming
• Changes in behavior
• Smaller fecal pellets

Prevention

Preventative dental care begins with understanding the vital role that chewing plays in a rabbit’s overall health. Rabbits are designed to consume tough grasses and fibrous vegetation for many hours each day. Their dental structure reflects this natural lifestyle. Because a rabbit’s teeth grow continuously throughout its life, the most effective way to maintain proper tooth wear is through a diet that closely mimics what rabbits would consume in the wild.

Unlimited Grass Hay: Unlimited access to high-quality grass hay should form the foundation of every rabbit’s diet, accounting for approximately 80 to 90 percent of daily food intake. The repetitive side-to-side chewing motion required for hay provides the most effective natural tooth wear. It requires extensive grinding, helping to maintain proper tooth length and alignment. Excellent choices include: Timothy, Orchard grass, Meadow and Bermuda grass. Alfalfa hay is a good choice for babies, senior or special need rabbits needing to add weight.

Forage: Offering a variety of fresh leafy greens, safe weeds, herbs, and forage plants can further support healthy chewing behaviors while providing important nutrients and enrichment. Fibrous plants such as dandelion greens and roots, plantain, raspberry leaves, and other rabbit-safe forage items encourage natural feeding habits and increase the amount of time a rabbit spends chewing throughout the day.

Encourage Enrichment Chewing: Providing safe chew toys and natural materials such as untreated apple branches, willow sticks, grass mats and seagrass products as enrichment toys can also help satisfy a rabbit’s instinctive need to gnaw.

Limit Pellet Consumption: excessive pellet feeding may reduce hay consumption and decrease natural tooth wear.

Health Checks: Regular observation at home is another important component of preventative dental care. Owners should routinely monitor their rabbit’s eating habits, body weight, grooming behavior, and overall demeanor for subtle changes that could indicate the early stages of dental disease. Routine veterinary examinations are equally essential, as many dental problems develop deep within the mouth where they cannot be easily seen during casual observation. During wellness visits, a rabbit-savvy veterinarian can evaluate tooth alignment, inspect the cheek teeth, assess oral health, and identify abnormalities before they progress into serious disease.

Final Thoughts…

Dental health is a cornerstone of overall rabbit wellness. Because rabbits rely on continuously growing teeth to process the high-fiber foods their bodies require, even minor dental abnormalities can have far-reaching effects on their comfort, nutrition, and digestive health. By understanding the unique anatomy of the rabbit mouth, recognizing early signs of trouble, and prioritizing a hay-based diet and regular veterinary care, you can dramatically reduce the risk of serious dental disease ensuring a more comfortable life for your rabbit.
