Stomatitis: inflammation of the mouth. More specifically, inflammation of the mucous membranes lining the mouth, which can include the cheeks, gums, tongue, lips, and the roof and floor of the mouth.
Stomatitis can be seen in both dogs and cats, though it is more common in cats. It is often seen alongside gingivitis. Stomatitis can reflect some serious underlying medical conditions, so if the signs of stomatitis are noted in your pet, a trip to the vet is in order.
