Why Do Some Dogs Grind Their Teeth?

Like humans, dogs are not aware of what they are doing when they are sleeping. Only a pet owner can tell if their dog grinds their teeth. However, keep in mind that not all dogs grind their teeth. But if they do, here are a few potential reasons why.


Oral Pain

Teeth grinding habit is a common reaction of dogs to discomfort or pain. Dogs do not usually show indications of pain the way people do. In fact, as part of their survival instinct, most dogs try to hide their discomfort by acting as usual as possible. From a physical perspective, teeth grinding may indicate something wrong in your dog’s mouth.dog grinding teeth

Potential reasons for oral pain include cavities, periodontal disease, tooth infections, fractured teeth, injury to the mouth lining or tongue, and oral growth or tumors. In addition, a few puppies will grind their teeth because of the teething process or when there is a loose tooth. Fortunately, most puppies grow out of the behavior once their adult teeth emerge.



A malocclusion, also known as an abnormal bite, happens when misaligned teeth or jaw abnormalities prevent the dog’s mouth from closing the teeth together appropriately and evenly. In fact, this condition can drive to grind teeth against other teeth automatically as a part of typical mouth movement.


Gastrointestinal Discomfort

Like oral pain, discomfort in the esophagus, intestines, or stomach can also make some dogs grind their teeth. This behavior is maybe a way for dogs to get temporary pain relief.


Stress or Anxiety

Stress and anxiety are the popular reasons for bruxism in humans. In canines, this response to anxiety and stress is rare yet can still happen. And similar to people, this form of teeth grinding may occur unconsciously while your dog is sleeping.

Dogs are well sensitive to their general surroundings. Any abrupt changes to their current circumstance or routine can cause pressure or stress. Some stress-related reasons may include a new baby or partner, moving home, or conflict in the home. When dogs feel unwell, this can appear in various behavioral changes such as teeth grinding.


Is Teeth Grinding Harmful?

Minor and occasional teeth grinding may not cause issues in a dog. Nevertheless, over time, these destructive behaviors can make significant wear to the tooth enamel and dentin. When worn out enough, the teeth might turn out to be seriously damaged and painful. If it exposes the pulp inside the tooth, the dog might develop a severe dental complication.
