Why is stomatitis triggered?

Most cases of stomatitis are due to so-called periodontal diseases, which are processes that affect the gums and teeth. Another possible cause is the presence of foreign bodies that become trapped between the teeth or around the tongue.

Less frequently, stomatitis is caused by lacerations or burns in the mouth. Furthermore, stomatitis is among the symptoms of some systemic diseases.


Stomatitis associated with diseases

In many occasions the appearance of stomatitis is due to associated diseases that originate it or that have it as one of its symptoms. Although there are many associated diseases, these are the most common :

  • Renal disease.
  • Uremia, which is a syndrome that occurs when toxic substances accumulate in the blood due to kidney malfunction.
  • Diabetes.
  • Hypothyroidism.
  • Leptospirosis.
  • Distemper.

Stomatitis symptoms

Although a veterinary review is usually necessary to diagnose stomatitis, there are a series of symptoms that can put us on alert. They are the following :

  • Extreme pain.
  • Hypersalivation
  • Bad breath odor.
  • I refuse food, not for lack of appetite, but for pain.
  • Swallowing difficulties
  • I reject manipulation by the mouth area.
  • The interior of the oral cavity appears red, inflamed and, in the most serious cases, ulcerated.

Types of stomatitis

Not all stomatitis are the same. It is possible to differentiate them into various types depending on their fundamental characteristics. In the following sections we explain the most important ones.

The saliva becomes very viscous, has pus and a brownish coloration. If we get to see the gums we will notice them very red and bleeding. Also, there are wounds. It can be triggered by periodontal disease.

Yeast stomatitis

It is called thrush or oral yeast infection. This case is less frequent. It appears more commonly in dogs that have been on antibiotics they have also removed normal bacterial flora. This causes yeast to proliferate.

The same happens in the case of dogs with a weakened immune system, generally because they already have some chronic systemic disease. What is typical of this stomatitis is that the gums and tongue are covered with soft white spots that end up joining together. Painful ulcers also develop.

Recurrent stomatitis

In this case we will find lesions in the mouth in places where there is continuous contact with the mucous membranes of the lips or gums. It may be due, for example, to a broken tooth or that shows an irregular edge that favors this friction. Bacteria, but also fungi, are identified when growing.

What is the treatment for stomatitis?

The first and fundamental thing is to locate the cause behind stomatitis. If there is an ongoing periodontal disease, the treatment will go through a thorough cleaning of the mouth. This is done with the dog under general anesthesia and is used to remove tartar or damaged teeth.

They are also going to be prescribed antibiotics to control bacterial infections or to prevent them from complicating the picture. Furthermore, pain relievers may be required to alleviate the severe pain.

Home care for a dog with stomatitis

In some cases, following the veterinaryn’s instructions, we will need to disinfect the dog’s mouth at home. Chlorhexidine diluted once or twice a day is normally used for this. The solution is poured onto a good piece of cotton wool and carefully passed all over the inside of the mouth, including teeth.

You also have to pay special attention to food. We will have to change the usual menu for a bland diet, almost liquid, to facilitate intake. For sale we will find cans with wet food formulated for convalescent dogs.

They can be diluted enough to be administered by syringe. Another option is to make homemade porridge. Likewise, it is considered beneficial to supplement with niacin. Of course, always with the veterinaryn’s prescription.
