Dental Pain in Dogs

By Malcolm Weir, DVM, MSc, MPH; Catherine Barnette, DVM

Why do pets experience dental pain?

According to numerous studies, between 80 and 89% of dogs have signs of dental disease by the time they reach 3 years of age. While you may think of dental disease as being primarily a cosmetic issue, the truth is that dental disease can also be painful for pets. Inflammation of the gums (gingivitis) can be uncomfortable on its own, while some pets may have more serious issues such as fractured teeth, tooth root abscesses, and oral tumors.

What are the signs of dental pain in dogs?

Dental pain in dogs may take on a wide variety of appearances, depending on the degree of pain and the dog’s personality.

In some cases, an affected dog may not show any outward signs of pain. Dental pain may only be noticeable on a veterinary exam when your veterinarian or veterinary technician uses a dental probe to apply pressure around the root of the tooth.

In other cases, however, you may observe signs of oral pain at home. These signs may include:

  • decreased interest in eating dry food
  • decreased interest in hard treats
  • chewing more slowly than usual
  • dropping food from the mouth while chewing
  • excessive drooling
  • pawing at the mouth
  • new or worsening resistance to having the face/mouth touched

If your dog is showing any of these signs, he may be experiencing dental pain. In addition to these signs, which clearly reflect pain, other signs of dental disease may also suggest the likelihood of dental pain. These signs may include bad breath, visibly loose teeth, or swelling of the muzzle.

What is the best treatment for dogs with dental pain?

The only effective treatment for dental pain is to address the dog’s underlying dental disease. While pain medication may help decrease pain levels for a short time, the pain will continue to recur until the underlying issue is addressed.

Your veterinarian will likely recommend a comprehensive oral health assessment and treatment (COHAT), which is performed under general anesthesia. First, your veterinarian will perform a pre-anesthetic exam and lab tests (typically a complete blood cell count [CBC] and serum biochemistry), to assess your dog’s overall health prior to anesthesia. Your dog will then be fully anesthetized to permit a complete oral evaluation and dental cleaning. The tartar will be scaled off your dog’s teeth, allowing the entire tooth to be seen properly. X-rays may also be performed, to allow evaluation of the tooth roots and issues that may occur under the gumline. Your veterinarian will also perform a thorough oral exam, carefully evaluating each of your dog’s teeth and the gum tissues.

Once your dog’s teeth have been thoroughly cleaned and evaluated, your veterinarian will come up with a treatment plan for any dental issues that have been discovered. This may include extraction of diseased teeth or advanced dental procedures such as a root canal. These procedures may be performed on the same day as the cleaning but, in advanced cases, your veterinarian may spread the dental procedures over multiple visits to minimize anesthesia time and stress to your dog. Additionally, your veterinarian may prescribe oral medications (antibiotics or pain medication) for your dog.

Can dental pain be prevented?

The best way to prevent dental pain is to ensure that your dog receives regular dental care. There are two components to dental care: home care and veterinary care.

The optimal home dental care is to brush your dog’s teeth daily. The goal of brushing is to remove plaque (the fuzzy accumulation of food particles and bacteria that develops on teeth). Once plaque sits on the teeth for approximately 24 hours, it begins to harden into tartar, so it is important to brush your dog’s teeth daily. If your dog will not tolerate daily brushing, your veterinarian may be able to offer tips to make brushing more tolerable. Alternatively, your veterinarian can recommend oral rinses and/or medicated chews that may help promote your dog’s oral health. There are also several prescription dog foods on the market (such as Hill’s T/D® or Royal Canin Dental®) that help keep the teeth clean as your dog chews.

Regular veterinary dental care is also important to your dog’s oral health. In general, most dogs should have a comprehensive oral health assessment and treatment  once yearly. Young dogs may be able to go a couple of years before their first dental cleaning, depending on their genetic predisposition for dental disease and the effectiveness of your home care, while older, small-breed dogs may need dental care as often as every six months.
