sometimes it can be a sign of an illness so you should go to the vets to get your cat checked out. the vet may also give you some medication to treat the condition.

First, let us review what plaque is. Bacteria play a major role in the formation of plaque. Bacteria live on remnants of food in the mouth. When bacteria combine with saliva and food debris in the channel between the tooth and gum, plaque forms and accumulates on the tooth. When bacteria continue to grow in the plaque and, as calcium salts are deposited, the plaque hardens to become a limestone-like material called tartar. If the chronic stomatitis/gingivitis is due to a plaque intolerance, then it is essential we remove all plaque and keep it off. This is accomplished through: * regular dental cleaning and polishing by your veterinarian * brushing a cat's teethfluoride application by your veterinarian * extraction of teeth with resorption lesions or severe periodontal disease * daily home care, including brushing and the application of 0.2% chlorhexidine * antibiotics * corticosteroids * good nutrition, often with vitamin supplements since these cats may not eat as much as they should because of the discomfort Unfortunately, even with this intensive care, the disease often progresses and the only way to cure the disease and eliminate the very painful lesions is to extract all of the teeth in back of the large canine teeth (fangs). This may appear drastic, but in almost all cases it is the only alternative. In cases of juvenile onset gingivitis, professional teeth cleaning every 2 months and once- to twice-daily brushing at home for the first year or so of their life, may allow them to revert to a more normal status as they age.
