Causes
An exaggerated immune response to bacterial plaque, often associated with viruses (calicivirus, FIV, FeLV). The exact cause is not fully understood.
Diagnosis
Examination of the mouth plus assessment under anaesthesia. The vet will usually test for FIV/FeLV and calicivirus.
Treatment
The most effective treatment is usually dental extraction (partial or full): although it may seem drastic, cats eat very well without teeth and the pain disappears. Supported with anti-inflammatories and, in some cases, immunomodulators.
Prevention
Difficult to prevent. Dental hygiene, vaccination, reducing stress. Early detection prevents prolonged suffering.
