What is it?
The common wombat (Vombatus ursinus), like all vombatids, has teeth that grow continuously throughout its life, a bit like rodents. Dental malocclusion is a misalignment of the upper and lower teeth. When teeth no longer wear properly together, they grow in an uncontrolled manner. This causes pain, sores in the mouth and prevents the animal from eating well. It is a well-known condition among wombats kept in captivity or in care centers, particularly those who grew up orphaned and bottle-fed.
Commonly observed signs

The first signs are often discreet. The animal eats less, more slowly, or drops its food. He may drool unusually or have unpleasant breath.\n\nWhen looking at the mouth, we sometimes notice abnormally long, sharp or poorly oriented teeth, which hurt the tongue, cheek or palate. These wounds can become infected and swell.\n\nAt a more advanced stage, the wombat loses weight because it is no longer able to eat properly. He becomes despondent, his coat loses its shine, and he may be less active than usual.
When to consult without delay
This list does not replace veterinary advice. It gathers situations that justify a prompt consultation.
Causes and risk factors
The main cause is the continued growth of the wombat's teeth throughout its life. Normally, natural wear and tear from chewing fibrous and abrasive food (grasses, roots) maintains a balance. If this balance is disrupted, the teeth grow too much and become misaligned.\n\nIn orphaned wombats artificially bottle-fed at a young age, the jaw can develop abnormally due to lack of suitable mechanical stimulation, which promotes poor dental alignment from the start.\n\nTrauma (shock, fall, bite during a fight) affecting the jaw or a tooth can also trigger localized malocclusion.
Wombats raised in captivity or in rescue centers, particularly those taken in very young and orphaned, are the most affected. A diet that is too soft, not very fibrous or not very abrasive, which does not allow natural wear of the teeth, increases the risk.\n\nAnimals that have suffered facial or dental trauma, as well as those with a congenital jaw anomaly, are also more exposed.
Diagnosis and care
Diagnosis is the veterinarian's responsibility, based on clinical examination and laboratory tests. Care is decided case by case.
The veterinarian performs a thorough examination of the mouth, often under anesthesia or heavy sedation because wombats are difficult to handle while awake and the oral cavity is difficult to access. He assesses the alignment of the teeth, looks for injuries, abscesses or areas of tartar.\n\nDental x-rays may be necessary to assess the condition of the roots and jaw bone, particularly if deep infection is suspected.
Treatment
Treatment is mainly based on specialized dental care: grinding or trimming of excess teeth to restore correct contact between the jaws, carried out under general anesthesia.\n\nIn the event of an associated infection, antibiotic treatment may be prescribed by the veterinarian. Painkillers and anti-inflammatories are often combined to relieve the animal during the recovery phase.\n\nAn adjustment of the diet, with more fiber, generally accompanies the treatment to limit recurrences. In severe or recurrent cases, regular dental checkups for life may be necessary.
Treatment depends on the cause and the animal's condition: it must be determined by a veterinarian. No self-medication.
Prevention
The best prevention is to offer a diet as close as possible to the wombat's natural diet: grass, good quality hay and fibrous plants which promote regular wear of the teeth through chewing.\n\nIn young bottle-fed orphans, gradual weaning towards a solid and fibrous diet as soon as possible helps the proper development of the jaw.\n\nRegular dental check-ups by a veterinarian accustomed to exotic animals make it possible to spot the start of malocclusion before it becomes severe.
Possible complications
Untreated malocclusion can lead to chronic mouth sores, dental abscesses, jaw bone infection, and significant weight loss due to difficulty eating. In severe cases, the animal can become severely malnourished.
When to see a veterinarian
The animal eats less or avoids hard foods.\nIt drools unusually or has bad breath.\nTeeth appear visibly long, broken or misaligned.\nWeight loss or depression sets in.\nSwelling of the muzzle or jaw is observed.
Prognosis
The prognosis is generally good if the malocclusion is identified early and treated regularly with appropriate dental care. On the other hand, advanced cases with bone infection or significant weight loss require longer treatment and the prognosis becomes more guarded.
Frequently asked questions
Why are wombats prone to tooth problems?
Their teeth grow continuously throughout their lives, like those of rodents. Without sufficient wear and tear through a fibrous diet, they can become too long and misaligned.
Should a pet or care center wombat have regular dental check-ups?
Yes, it is recommended, especially for orphaned animals bottle-fed young, who are at greater risk of developing malocclusion.
Can malocclusion heal on its own?
No, it requires veterinary intervention because the teeth continue to grow. Without correction, the problem gets worse over time.
Does this disease also affect wild wombats?
This is rarer, because their natural fibrous diet wears down the teeth properly, but trauma can also be the cause in a wild animal.
