Cavities in Dogs

What Are Cavities in Dogs?

Dogs, like humans, can suffer from cavities, although they are less common in our furry friends. Yet, neglecting a dog’s oral health can lead to painful dental conditions, including cavities. It’s crucial for pet parents to recognize the signs of cavities in dogs and understand how they are managed.

Cavities, also known as dental caries, are areas of tooth decay that develop due to prolonged exposure to oral bacteria. When bacteria linger on the teeth, particularly after consuming carbohydrate-rich foods, they produce acid that corrodes the outer enamel layer of the tooth. With time, this erosion progresses, affecting the dentin (the layer beneath the enamel) and the pulp chamber (the inner part of the tooth containing nerves and blood vessels).

Typically, cavities manifest as dark spots on the tooth’s surface, often found in the pits rather than on smooth surfaces, usually more noticeable on the dog’s back teeth. Although the exact prevalence of cavities in dogs remains unclear, a report suggests that slightly over 5% of adult dogs referred to dental services exhibit cavities. However, more prevalent dental issues in dogs include fractured teeth and gum disease.

While cavities in dogs aren’t considered emergencies, it’s essential to seek a dental evaluation from your veterinarian if you suspect your dog may have one. Treatment options may vary and could require the expertise of a veterinary dentist. If your vet’s practice cannot handle the treatment, ask for a referral to ensure proper care for your dog’s affected tooth.

Symptoms and Types

Signs of cavities in dogs can manifest as:

  1. Increased drooling (hypersalivation)
  2. Presence of a dark spot on the tooth
  3. Decreased appetite
  4. Difficulty in keeping food in the mouth while eating
 

Causes

Cavities are less common in dogs compared to humans, partly due to their diet, which typically lacks high levels of sugars and acids. Additionally, dogs possess cone-shaped teeth and more spacing between them, further reducing the likelihood of cavity formation.

Dogs consuming diets rich in fermentable carbohydrates, poor-quality food, and table scraps may face a higher risk of developing cavities compared to those on a high-quality diet. Regular dental care also plays a role in minimizing the chances of dental caries in dogs.

Genetics also contribute to a dog’s susceptibility to cavities and other dental issues. Breeds prone to cavities often overlap with those predisposed to dental diseases. Examples of such breeds include Chihuahuas, Pugs, American Bulldogs, French Bulldogs, Standard Poodles, Miniature Poodles, Shih Tzu, and Dachshunds.

Diagnosis

Veterinarians can potentially identify cavities on a dog’s tooth during a routine examination while the dog is awake.

However, for a comprehensive oral assessment and accurate diagnosis of cavities, including exploration of any painful areas, your dog needs to be under anesthesia. Anesthesia enables the veterinarian to conduct a thorough dental cleaning, as well as obtain X-rays of affected teeth, which are crucial for devising an effective treatment plan.

Treatment

The treatment for your dog’s cavity depends on the severity of the condition. Through X-rays, your veterinarian can assess whether the pulp chamber is exposed and if the tooth’s vitality is compromised.

For less severe cavities, debridement and filling, similar to human dental fillings, are typically sufficient. The affected portions of the tooth are removed, and the cavity is filled.

Teeth with more extensive lesions may require root canal therapy and restoration. In severe cases, extraction of the tooth may be necessary. Dental procedures to address cavities or extract teeth involve anesthesia and can take approximately one hour or longer. Following dental surgery, your veterinarian will provide guidelines to ensure proper healing of the surgical site.

 

Living and Management

Following surgery, dogs typically wake up from anesthesia within a few hours and show signs of restored appetite and energy within one to two days.

If your veterinarian prescribes antibiotics, such as clindamycin, or pain medication like carprofen, it’s important to adhere to their instructions for administering these medications. Your vet might also suggest limiting access to hard foods and specific toys post-surgery. Consult your veterinarian regarding potential dietary adjustments or restrictions on chew toys and activities like tug-of-war for your dog.

Prevention

The primary and most effective measure pet parents can take to prevent their dog from developing cavities is to brush their dog’s teeth regularly. Daily brushing is highly recommended.

Discuss with your veterinarian about various dental products, treats, water additives, and other options available, although it’s important to remember that none of these substitutes brushing your dog’s teeth in terms of effectiveness.

Maintain a high-quality diet for your dog and steer clear of sugary treats. If you have any queries about your dog’s dietary needs, consult your veterinarian who can provide suitable recommendations.

Regular veterinary checkups are crucial for safeguarding your pet’s dental well-being. Your veterinarian will advise on the need for dental cleanings, which enable a comprehensive evaluation of your dog’s dental health. Additionally, your vet may apply sealants to teeth deemed susceptible to cavity formation.

Cavities in Dogs FAQs

What are the stages of a dog’s cavity? Cavities progress through five stages:

  • Initial stage: Only the enamel, the outer white layer of the tooth, is affected.
  • Second stage: The cavity extends into the dentin, the layer beneath the enamel.
  • Third stage: Damage reaches the pulp chamber in the center of the tooth, containing blood vessels and nerves.
  • Fourth stage: The overall structure of the crown is compromised.
  • Fifth stage: Most of the crown is lost, and the tooth’s roots may be exposed.

How do you treat a dog cavity at home?

You cannot treat a dog’s cavity at home. Veterinary intervention is necessary to prevent further damage to the dog’s tooth and alleviate pain.
