Dental Corner: Diagnosing and treating chronic ulcerative paradental stomatitis


If patients do not tolerate prednisone, azathioprine can be used to control the inflammation. Start azathioprine at a dosage of 1 to 2 mg/kg given once a day, and if effective, taper the dosage to 1 mg/kg given every other day after three weeks. Additional monitoring for patients receiving azathioprine includes frequent CBCs. If evidence of bone marrow depression is observed, discontinue the azathioprine, and explore other treatment options.

In patients in which medical therapy is not successful or not advisable, healthy teeth can be extracted to achieve beneficial results.1,2 In some cases, extracting the caudal teeth (molars and premolars) will be enough. In patients in which caudal teeth extraction fails to achieve clinical remission, extract the remaining teeth. In my experience, CUPS almost always resolves when all of a dog's teeth have been removed. Dogs with no teeth can eat and live normal lives. But keep in mind that often, after all the teeth are extracted, a dog's tongue will hang out of its mouth.


CUPS is a chronic condition that requires lifelong patient monitoring. Always stress to owners that this condition will most likely require a lifetime of therapy. If owners run out of their dogs' medication, clinical signs of CUPS commonly recur. A cure may be achieved, however, by extracting many or all of the teeth. Because of the potential side effects from the medications used to treat CUPS, periodic physical and oral examinations should be accompanied by appropriate hematologic tests. Routine dental prophylaxis (every four to six months) should be part of a complete oral hygiene program when the goal is to save teeth.
