Stomatitis




Stomatitis is often seen in conjunction

with Resorptive Lesions, but not always.

Stomatitis can be very challenging to treat.

  


 


Stomatitis is defined as inflammation of the mouth.
While occasionally seen in various forms in dogs, it is much more common in cats. Cats with stomatitis often have severe oral pain, have difficulty eating, and may drool excessively. They have a greatly decreased quality of life.

There are two patterns of inflammation seen. The most common is where there is severe inflammation
of the gums next to the teeth. When you open their mouths, you will see redness along the gum lines. These cats also often have fairly severe periodontal disease, and they may have various stages of Resorptive Lesions present as well. This type of stomatitis can be seen in the image to the right.


In addition to inflammation next to the teeth, some cats will also have severe inflammation in the back of the mouth, sometimes extending down their throat. This pattern of inflammation is also called Faucitis, and it is more severe than the kind of stomatitis that just affects the gums. You can see the red sores in the back of this cat’s mouth in the image to the right.

We do not know what causes stomatitis in cats. An immune system problem is suspected to be the cause. The cats may be reacting to plaque and bacteria on the teeth, or some feel that they may be reacting to the enamel of the teeth themselves. There are some associations between stomatitis and various feline infectious diseases, but there is not much science behind those associations. But let me re-emphasize that we do not know what causes stomatitis in cats. This means that there is no universally accepted way of treating stomatitis.

Because we do not know what causes stomatitis, we are a little handicapped when it comes to treating it. Some veterinary dentists view stomatitis as a medical condition and recommend starting slow, with dental cleanings and medication, then progressing to limited extractions, then progressing step-wise to more extractions if needed. Others view stomatitis as a surgical disease, going straight for extractions, then medical treatment if needed. I personally tend to do the slow, staged treatments in cats with mild stomatitis, and opt for immediate extractions in cats with severe stomatitis and any degree of faucitis.

Extractions in a cat with stomatitis can be very difficult and time-consuming. It is vital that every last bit of tooth be removed. If even a small root fragment is left, the stomatitis will persist. The teeth to be extracted are often unhealthy and diseased themselves, and they can break easily. There are a few tooth roots that can be left safely, but X-rays are important to evaluate which ones can indeed be left and which can't. It is also vital that as much diseased gum tissue as possible be removed, and that the extraction sites be sutured closed. Pain control is another very important concern. Because of the delicate and time-consuming nature of extractions in a cat with stomatitis, it is relatively expensive procedure. It can cost from $400 to $800, and in certain cases even more, for this kind of procedure and the associated medications.

In the past, steroids and antibiotics have been advocated as a good treatment for stomatitis. While I feel that this treatment has some use, it works best in the mild cases and the cases that have already had extractions. Lasers have been proposed as a treatment for stomatitis, and while I find them useful to a degree, I am not yet convinced that the benefit gained is worth the expense and the risk of the multiple anesthetic episodes required. I do on occasion use it as a one-time treatment when patients are under anesthesia for extractions, however.

It is important to state for the record that some cats, especially those with severe stomatitis and faucitis, may never reach the point that they are fully cured, even if every tooth is extracted. Some of them will require treatments from time to time throughout their life. Some will flare up every few months. However, it is also important to note that even those cats that do not clear up entirely are much much more comfortable and happy after extractions than they were before, even if they may have a flare-up from time to time.
