Dog Grinds Teeth When Yawning, What Could Be Wrong?

Teeth grinding or bruxism can also happen to pets like cats and dogs. In some cases, you may notice a dog grinds teeth when yawning, sleeping, or simply laying down.

This phenomenon is highly associated with dental issues, though there can also be other underlying reasons for this condition. In this post, I will discuss why your dog grinds its teeth and what you can possibly do to stop or prevent it.

Dog Grinds Teeth When Yawning

Reasons why a dog grinds its teeth

If your pooch is grinding its teeth when yawning or on random occasions, the following reasons might explain why:

1.    Oral pain

The most common reason why canines experience teeth grinding is oral pain. A dog will grind its teeth intensely as a way to soothe the pain in its mouth.

This habit is detrimental for a variety of reasons. The crown can fracture and expose the pulp when your dog applies pressure on its teeth.

When this happens, infection and diseases can occur. It will also lead to further pain, tooth misalignment, and a slew of other dental problems for your pet.

Aside from that, teeth grinding can damage the surrounding teeth over time. This will create an endless cycle of pain and dental issues.

2.    Misaligned teeth

Canines with malocclusion or misaligned teeth are also likely to experience bruxism. An abnormal bite can cause the teeth to rub or grind with each other, even if your pet doesn’t intend to.

Misaligned teeth can trigger a slew of problems. This can wreak havoc on your pet’s dental health if not addressed.

In this case, bringing your dog to the veterinarian is best. An assessment will be done on the malocclusion and the vet will recommend solutions to help fix it.

Depending on the malocclusion, the affected tooth could be removed. Nevertheless, some vet clinics offer ‘dog braces’, a pretty new procedure to fix teeth misalignments in canines.

3.    Gastrointestinal problems

Take note that dental issues are not the only possible reason behind teeth grinding in dogs. Gastrointestinal issues can also be a culprit as to why your canine’s teeth grind when yawning or doing random activities.

Pain or discomfort in its digestive system may cause a dog to clench its teeth to soothe itself. In some cases, doggos will grind their teeth as a response to the pain or distract themselves from the discomfort.

4.    Stress and anxiety

Although rare, some dogs may grind their teeth due to chronic stress or anxiety. This is more likely to occur on breeds known to be predisposed to separation anxiety like Border Collie, Labrador Retriever, Beagle, and Jack Russell Terrier.

Aside from teeth grinding, anxious dogs may also chatter with their teeth. This could be paired with intense vocalization, unsettled behavior, aggressive chewing, and other destructive ways.

How to stop a dog’s teeth from grinding

Most cases of teeth grinding in dogs can be alleviated if not fixed. The key here is identifying the root cause of the problem and involving the vet in the process.

Also, there’s no one-size-fits-all when it comes to teeth grinding in canines. It’s important to assess your pet’s condition well to know the best solution for its bruxism.

Here are some of the helpful tips you can do to ease your dog’s teeth grinding:

1.    Inspect its mouth regularly

It’s important to inspect your dog’s mouth regularly, whether it’s grinding its teeth or not. This way, you’ll know if there are abnormalities in its mouth before it becomes a big problem.

Misaligned teeth, unusual gum discoloration, and swelling should prompt you to consult a veterinarian. These are common symptoms of dental problems that can lead to teeth grinding.

2.    Observe proper dental hygiene

Proper dental hygiene is indispensable in preventing dental problems like teeth grinding. While it’s not a cure for anatomy-related bruxism, it can still help in preventing complications from occurring.

Make it a habit to brush your dog’s teeth at least once a week. If you can do it daily, it would be much better.

Aside from that, you should consider using water additives to further keep your pet’s mouth clean. Just remember that there’s no alternative to regular brushing.

3.    Provide appropriate chew toys and treats

When giving chew treats and toys to your dog, make sure that it’s age and breed-appropriate. This is to avoid damage and injuries to the canine’s mouth, which can trigger teeth grinding.

Overall, avoid very hard treats like animal bones. Aside from being very stiff, animal bones can also splinter and cause blockages in your pet’s stomach.

4.    Invest in regular vet checks

No matter how healthy your dog’s teeth look, you should still bring it to the vet for annual dental checks. This is to spot early signs of dental issues before it leads to serious conditions like teeth grinding, periodontal disease, and tooth loss.

Take note that annual vet checks are cheaper than having to pay for an expensive dental treatment. Being proactive will both save your dog from discomfort and you from the exorbitant vet bill.

5.    Treat dental problems as they arise

Lastly, you should treat the dental problems of your dog as it arises. This way, the problem won’t worsen and cause serious dental issues.

In general, it’s much cheaper and easier to treat a dental problem in dogs at its early onset. Putting off treatment won’t just cause expensive vet bills, but also unnecessary discomfort for your pet.
