Dogs come in many shapes and sizes, but all of them can be affected by dental and periodontal disease.

Here are some important things to consider for dental cleanings in dogs…

What’s the Normal Dentition for a Dog?

While it’s important to recognize what’s abnormal, it’s just as important to know what’s NORMAL when it comes to a dog’s teeth.

For example, many clients ask questions like ‘how many teeth does a dog have?’. A quick and confident answer can help instill confidence in the veterinarian’s knowledge.

Also, during a dental procedure, knowing the expected number of teeth will help a vet know if any teeth are missing—an abnormal finding that warrants further exploration and dental radiographs.

It also helps to know how many roots each tooth has, as well as the approximate length and direction of each root. That way, a vet can plan for the most efficient way to extract a tooth, and it will be less likely that any root tips are left behind.

What Are the Most Common Dental Issues in Dogs—and in Specific Breeds?

Periodontal disease is, of course, very common, affecting more than two-thirds of dogs by three years of age. 

But while any breed can be affected, certain breeds are more prone to developing tartar and periodontal disease quickly. Often, this happens to small or brachycephalic breeds due to tooth crowding.

Big dogs, on the other hand, maybe more likely to suffer traumatic tooth fractures.

While it’s important to keep a lookout for anything that could be part of a disease process, knowing the common issues in each size and breed of dog could help a vet know where to look for issues and pick up on subtle or early changes.

When Should Dental Radiographs be Taken?

Dental radiographs are considered the standard of care for dental procedures. Some estimates state that dental x-rays can reveal about 40% more pathology than can a visual oral examination alone.

This leads to better patient care. Also, the x-ray images can help clients visualize their dog’s dental health status and therefore better understand the importance of the treatments a veterinarian recommends.

So, when and how should dental radiographs be performed?

Many experts recommend taking a full set of dental radiographs immediately after anesthesia induction. Usually, this task is performed by a skilled vet tech or nurse, along with anesthesia monitoring. 

Performing radiographs prior to the cleaning gives the vet a chance to review the radiographs. These findings, along with a visual assessment of the patient’s mouth (including charting), gives a lot of information to support a call to the owner, if needed for additional treatments.

Some veterinarians prefer to do radiographs after the dental cleaning is performed, so they can first remove large chunks of calculus that could interfere with radiographic interpretation. There’s nothing wrong with this, and every practice should do what works best for them. 

The most important thing is probably to have a consistent protocol, to improve efficiency.

It’s worthwhile to invest in training for this important skill. Consider sending team members to a conference or course, or asking the company that sold the dental x-ray equipment if they offer training. 

Since dogs differ greatly in size, it helps to have more than one size of film/plate/sensor available. In order to be diagnostic, x-ray images must show 2-3 mm of bone from the apex of the root. The crown of the tooth doesn’t necessarily need to be included. 

For routine cleanings, one set of radiographs may be all that is needed. But for patients who are receiving extractions or more advanced procedures, it’s beneficial to perform post-op dental x-rays. This confirms that everything was done properly and safely, in case any new concerns arise later.

Tips for Cleaning a Dog’s Teeth During a Dental Procedure

After radiographs and charting are finished, the typical dental procedure consists of scaling and polishing. 

Here are a few tips for the dental cleaning:

• Scaling of the enamel, above the gumline, can be done with an ultrasonic/and or hand scaler. 

• It’s recommended not to spend more than 10-15 seconds on a tooth with the ultrasonic scaler, to avoid overheating and damaging the tooth.

• Subgingival cleaning may be performed by hand, or via a special “subgingival tip” on the ultrasonic scaler that is designed to be used on a lower setting and is less prone to overheating the tooth. For simple dentals without significant gum recession, this may be all that is needed.

• If using ultrasonic scalers, many experts recommend following up with hand scaling for more detailed work or hard to reach places, to ensure no tartar is left behind.

• For periodontal pockets ranging from 3-5 mm with no other pathology (mobility, etc.), closed root planing and subgingival curettage may help to reestablish the health of the pocket and soft tissue attachments to the tooth.

• For pockets deeper than 5 mm where the tooth is being treated (rather than extracted), open root planing is recommended. Referral to a specialist may be best. 

• It’s important to stock tools in different sizes to accommodate different breeds of dogs. Having the right tools can make a veterinary team member’s life much easier and allow them to more easily reach and clean crevices or tight spots.

Due to the prevalence of periodontal disease, there’s no doubt that dental health is important for a dog’s wellbeing.

Client expectations are evolving. Many devoted pet owners research dental procedures online and expect a high level of care for their dog’s oral health needs.

By investing in dentistry—and then communicating the value of each step to their clients—a veterinary practice can bring in income while providing excellent care to their canine patients.
