canine-chronic-ulcerative-stomatitis
Canine chronic ulcerative stomatitis is an extremely painful mouth disease for dogs.
What is it exactly?
Simply put, it is as if your dog’s immune system overreacts (much like a very severe allergy) to normal dental plaque. Instead of just causing tartar or gum problems, this reaction creates severe inflammation and very painful sores (ulcers). These sores are not found on the teeth, but on the soft parts of the mouth, such as the inside of the cheeks, lips, tongue, or palate. In fact, these sores are sometimes called “contact lesions” because they form exactly where the inside of the cheek rubs against plaque-covered teeth.
How does the veterinarian find the problem?
To confirm that it is indeed CCUS and to see the extent of the damage, the process is done in a few steps:
- A visual examination of the mouth in the consultation room.
- A comprehensive exam and dental X-rays while your dog is asleep (under general anesthesia, so they feel no pain).
- In some cases, a small tissue sample (a biopsy) to ensure it is not another disease.
How can I relieve my dog?
The main goal is to eliminate the pain. Here is how we proceed:
- The deep clean (Scaling): Since dental plaque is the number one enemy, a professional cleaning under anesthesia is the first step. Afterwards, you will need to brush your dog’s teeth at home (once their mouth is healed and they are no longer in pain).
- Removing the teeth causing the problem: Very often, a simple cleaning is not enough to make the sores disappear. The most effective solution is then to extract the teeth rubbing against the ulcers. This may sound scary, but it provides immense relief for the animal. A dog eats and lives much better with a few missing teeth than with a bloody mouth and unbearable pain.
- Medications: Anti-inflammatories can help manage pain and inflammation, but pills alone do not cure the disease. They are given in addition to the rest of the treatment.
