Cavity in Dogs: Causes, Symptoms & Treatment

Just like humans, dogs need a consistent dental routine to maintain their oral health. Here, our vets discuss the causes, symptoms, and treatments of cavities in dogs.

Cavities in Dogs

Like people, dogs can develop cavities from a lack of oral hygiene over time. Below are some causes of canine cavities that owners should know about in order to prevent them.

The Cause of Cavities in Dogs

Just like in people, as our dogs eat, the leftover food debris residue is consumed by bacteria that naturally live in their mouth and turned into plaque. 

You may recognize plaque as the while substance that sticks to your teeth over the course of the day. Plaque is mildly acidic and quite sticky, slowly eating away at the protective outer layers of your dog's teeth over time (as well as causing the mild-to-severe bad breath we often think of as normal more middle-aged or senior dogs).

If your dog's mouth is left uncleaned for long enough, the acidic plaque on your dog's teeth and cause large or small holes in their enamel, called cavities,m tooth decay, or dental caries. 

Certain pre-existing conditions in your pup's mouth may make them more likely to develop cavities in addition to a lack of routine cleanings. These include:

  • Gaps between teeth and gums caused by gum recession
  • A low pH level in your dog's saliva
  • Weaker-than-normal tooth enamel (caused by poor mineralization)
  • High-carbohydrate diet
  • Poor general health
  • Misaligned or crowded teeth in your dog's mouth

The Symptoms of Canine Cavities

The following are some of the most common symptoms that are caused by or accompany a dental cavity in a dog:

  • Abnormal chewing, drooling, or dropping food from the mouth 
  • Discolored teeth
  • Noticeable Tartar buildup
  • Bleeding from the mouth
  • Bad breath 
  • Reduced appetite or refusal to eat 
  • Pain or swelling in or around the mouth

For some pups, the pain and discomfort of a cavity is enough to stop them from eating enough (or eating altogether). If you notice any of the above symptoms, bring your dog to your vet for a dental checkup and treatment as soon as possible.

Treatments for Your Dog's Cavity

There are two broad categories of treatment that can be applied to cavities in dogs: professional treatment of existing cavities and preventive treatment of cavities early in their development or before they have a chance to arise in your pup in the first place. 

Restorative Dental Treatment For a Canine Cavity

The precise treatment for your dog's cavity will depend on its severity. If you have caught a cavity just as it was starting to form, your vet may use a fluoride wash or bonding agent to protect the site against further degradation and will monitor it in the future. 

When a dog's cavity progresses any further than that, the disease enamel, dentin or pulp will need to be removed and the tooth restored with a filling, root canal or other restorative treatment. If the cavity has progressed far enough (to stages 4 or 5), the tooth may not be truly treatable and may have to be removed from your pup's mouth to prevent further degradation of their oral health. 

Recovery from filling or tooth removal treatment are often quite quick, but you may have to provide specialized after-care to your dog in order to prevent them from harming their mouth or their new filling.

Routine Care to Prevent Cavities

Far and away the most reliable way to preserve your dog's dental and overall health, as well as fight cavities, is to maintain a regular routine of oral hygiene care at home, with specialized toothbrushes and toothpaste in textures and tastes custom-made for dog mouths.
