Common dog teeth problems

Dental problems that affect dogs are plaque and tartar buildup; gingivitis; tooth root abscesses; cracked or broken teeth.

Dental problems are among the most common health issues in dogs. Dog teeth issues can hurt a dog’s quality of life and overall health.

Signs of dental problems in dogs

  • Bad breath
  • Discoloration of teeth
  • Visible tartar buildup
  • Inflamed gums
  • Bleeding gums or blood spots seen on dog toys/bedding
  • Pawing at the mouth
  • Swollen face
  • Loss of appetite
  • Difficulty eating
  • Excessive drooling
  • Lethargy

Many dogs will not show signs of oral pain until it is severe. Signs of oral pain may include pawing at the mouth or face, lack of appetite, difficulty eating, lethargy, whining, and acting withdrawn from family members.

Plaque and tartar buildup

Plaque is a biofilm that develops on the teeth. It is a whitish substance primarily composed of bacteria. The plaque’s foul odor worsens the longer it remains in the mouth. Plaque on the teeth causes tooth decay and gum irritation.

If not removed by brushing within about 24 to 48 hours, the plaque hardens and turns into tartar, a yellow or brown-colored substance also known as calculus. Tartar remains fixed to the surfaces of the teeth and cannot be removed without being scraped off with a hard object, like a professional dental scaler. Its contact with teeth and gums causes further tooth decay and gum irritation.

Plaque and tartar are the primary causes of loose teeth and gum disease. The main signs dog owners will notice are bad breath, discolored deposits on teeth, and a red, swollen gum line (called gingivitis). As dental disease progresses, owners may notice bleeding gums and worsening breath.

Periodontal disease

“periodontal” refers to the gums and bones surrounding the teeth. When plaque and tartar remain in the mouth, bacteria make their way under the gum line, eating away at the tissue and bone that hold the teeth in place.

Periodontal disease begins with gingivitis. As the disease progresses, bone and soft tissue will be lost around the teeth. As the vital support structures for the teeth degrade, pockets develop around the roots of the teeth, allowing food, bacteria, and debris to collect and form dangerous infections.3 Over time, the teeth become loose and begin to fall out.

Oral infections

With periodontal disease, the open space around the tooth roots can become filled with bacteria, leading to an infection. The infection may manifest as a tooth root abscess.5 The bacteria-laden pocket around the tooth root fills with pus to fight the infection. The abscess may get so large that it leads to facial swelling and anatomical deformity.

Oral infections are often caused by periodontal disease, but they may also occur secondary to trauma in the mouth. Dogs that chew on sharp or hard objects may injure their mouths and develop infections.

Tooth fractures

Tooth fractures are common in dogs that are powerful chewers. Items like bones, antlers and very hard plastic can cause teeth to break.1 Most vets will tell you that your dog should not chew on anything harder than what you would want to bang hard on your knee.

The size of the chew can also contribute to tooth fractures. A large chew may make the tooth and chew line up at an angle that splits the outside of the tooth. This is known as a slab fracture. Pick chews that are small enough to hold in the mouth without swallowing by accident but are not so large that the dog needs to have a fully open mouth to chew on them.

Organ damage

Dog teeth problems are not just limited to the dog’s mouth. The bacteria in the plaque and tartar can easily enter the bloodstream, especially if your dog has irritated gums, like in the case of periodontal disease. This bacteria makes its way through the bloodstream and reaches the heart, kidneys, liver, and even sometimes the brain. This can cause serious organ diseases, worsen existing diseases, and even cause organ failure.6

Retained baby teeth

All puppies have baby teeth, also called deciduous teeth, that are supposed to be pushed out by the growth of adult teeth. In most cases, a puppy’s baby teeth fall out, and the adult teeth take their place by the age of six months. However, puppies may retain deciduous teeth (the adult teeth come in, but the baby teeth remain).

There is no way to prevent retained deciduous teeth. However, your vet will likely recommend removing them under anesthesia to prevent the shifting of adult teeth and tartar buildup. Many vets will do this when the dog is already under anesthesia for a spay or neuter.

How to care for your dog’s teeth and prevent dental problems

The best way to prevent teeth problems in your dog is to begin a dental care routine. Daily tooth brushing is the gold standard, but not all dogs will tolerate this. Alternatives include dental chews and water or food additives. No matter what method you choose, look at your dog’s teeth regularly, so you can see problems before they become severe.

If your dog is showing signs of dental problems, be sure you visit your vet for an examination. In many cases, a professional dental cleaning under anesthesia is necessary to remove disease-causing tartar. Once clean, the vet can take x-rays, thoroughly examine the teeth, and determine the nature of the dental disease.
