Dog Dental Health Statistics 2026: Key Facts & Data

Dental disease is the most commonly diagnosed health problem in dogs — more common than ear infections, skin conditions, or obesity in many veterinary datasets. Yet it remains one of the most underestimated: in Banfield Pet Hospital's analysis of more than 3 million pets seen in 2023, 73% of dogs were diagnosed with dental-related issues.

This page compiles the most important canine dental health statistics from veterinary hospitals, universities, and professional associations. Every number below links to its source. Compiled September 2026; updated yearly.

Key Takeaways

Periodontal disease is the most common dental condition in dogs — up to 80% of dogs over age 3 show signs, according to Colorado State University.
73% of dogs seen at Banfield's 1,000+ U.S. hospitals in 2023 were diagnosed with dental-related issues (Banfield).
Dogs with advanced periodontal disease were 2.3× more likely to develop chronic kidney disease and 6.3× more likely to develop endocarditis in Banfield's data.
Extra-small breeds (under 14.3 lbs) are up to 5× more likely to be diagnosed with periodontal disease than giant breeds (Waltham Petcare Science Institute, via Banfield).
A routine professional cleaning typically costs $300–$700 in the U.S. (CareCredit).

How common is dental disease in dogs?

Periodontal disease — inflammation and infection of the tissues supporting the teeth — is the most common dental condition in dogs and cats. The American Veterinary Medical Association (AVMA) notes that by the time a pet is 3 years old, he or she will very likely already show some early evidence of periodontal disease, which worsens with age if preventive measures aren't taken.

Other large-scale sources paint a consistent picture:

Up to 80% of dogs over the age of 3 have periodontal disease, according to Colorado State University's veterinary school.
73% of dogs seen at Banfield's 1,000+ hospitals in 2023 were diagnosed with dental-related issues, based on more than 3 million patient records (Banfield, February 2024).
Approximately 90% of the canine population will have some degree of periodontal disease by middle age, according to Dr. Nadine Fiani of the Cornell Section for Veterinary Dentistry and Oral Surgery (via Cornell University).
Dental disease prevalence in dogs grew by 23% between 2006 and 2015, according to Banfield's State of Pet Health report (via dvm360).

Part of the reason the numbers are so high is simple anatomy: adult dogs have 42 permanent teeth (20 upper, 22 lower), and every one of them can accumulate plaque (PetMD). Puppies start with 28 deciduous ("baby") teeth, replaced by the adult set at around 6–8 months.

Dental disease and whole-body health

Poor oral health in dogs is associated with more than bad breath. Banfield's research, based on its national patient database, found measurable associations between advanced periodontal disease and systemic conditions:

Dogs with advanced periodontal disease were 2.3× more likely to develop chronic kidney disease and 6.3× more likely to develop endocarditis (infection of a heart valve) (Banfield).
The AVMA notes that kidney, liver, and heart muscle changes have been found in association with periodontal disease (AVMA).
Oral pain itself is common: poor oral health can be associated with pain, excessive drooling, bleeding, and reluctance to eat or drink (Banfield).

A note on interpretation: these are associations observed in large datasets, not proof that dental disease causes organ disease. Researchers continue to study the exact mechanisms, but the pattern is consistent enough that veterinary organizations treat oral health as part of whole-body health.

Professional dental care: what the data says

Veterinary organizations recommend that a dog's teeth and gums be checked at least once a year for early signs of problems (AVMA). A professional dental cleaning under anesthesia typically includes scaling above and below the gumline, polishing, and often full-mouth X-rays to evaluate tooth roots and jawbone.

On anesthesia-free cleanings: the American Veterinary Dental College does not recommend dental cleanings without anesthesia, because they do not allow cleaning or inspection below the gumline — where most dental disease occurs (AVMA). Colorado State's veterinary school adds that anesthesia-free dentistry addresses only visible plaque above the gumline, which can leave owners with a false sense of dental health. The AVMA notes that while anesthesia always carries some risk, it is safe overall and the benefits for dentistry far outweigh the risks (AVMA).

What does it cost? According to CareCredit's survey of U.S. veterinary costs, dental checkups and cleanings for dogs typically run $300 to $687. Their itemized estimates for pet dental care break down as follows (CareCredit):

Oral examination: $50–$100
Dental radiographs (X-rays): $150–$300
Ultrasonic scaling and polishing: $200–$300
Anesthesia: $300–$500
Oral surgery (e.g., extractions): $400–$1,000

Costs vary widely by region, clinic type, and disease severity — addressing dental issues early is consistently less expensive than treating advanced disease. The AVMA also sponsors National Pet Dental Health Month every February to raise awareness (AVMA).

Home dental care: what actually works

Professional cleanings handle what's already there; home care slows what comes back. The AVMA calls regular toothbrushing "the single most effective action" owners can take to keep their pet's teeth healthy: daily brushing is best, but brushing several times a week can also be effective (AVMA).

Colorado State's veterinary school recommends daily brushing with a soft-bristled brush and veterinary-approved toothpaste to decrease plaque accumulation and slow the progression of periodontal disease (Colorado State University).

For products beyond the toothbrush, the Veterinary Oral Health Council (VOHC) awards its Seal of Acceptance to dental diets, chews, water additives, and other products whose submitted study data meet the council's preset standards for plaque or tartar control. Owners can check the current list of accepted products at vohc.org. The AVMA advises talking with your veterinarian before choosing dental products, treats, or dental-specific diets, since not all marketed products are effective (AVMA).

Breed and size differences

Chihuahua, a small breed at higher risk of periodontal disease

Not all dogs face the same dental risk. Research from the Waltham Petcare Science Institute, using Banfield's patient data, found that extra-small dog breeds (under 14.3 lbs) were up to five times more likely to be diagnosed with periodontal disease than giant breeds (over 55 lbs) (Banfield). The same research found that persistent deciduous teeth ("shark teeth") — retained baby teeth that can cause bite misalignment and gum disease — were significantly more common in extra-small breeds.

Banfield's 2023 breed ranking reinforces the pattern: 8 of the top 10 breeds with the highest rates of oral health issues were smaller dogs:

Beagle — 80.7% diagnosed with oral health issues
Terrier breeds — 79.7%
Dachshund — 79.3%
Chihuahua — 78.9%
Yorkshire Terrier — 78.4%
Maltese / Miniature Schnauzer — 77.8%

Larger dogs aren't off the hook, though: 70% of Golden Retrievers, 68.3% of Siberian Huskies, and 62.5% of Pitbulls seen at Banfield were also diagnosed with dental issues. Regionally, the Midwest had the highest rate of canine oral health diagnoses (76.7%), with Iowa (85.4%) topping the state list (Banfield).

Methodology

This page was compiled in September 2026 from published sources: veterinary hospital databases (Banfield), professional associations (AVMA, AVDC, VOHC), and university veterinary schools (Colorado State, Cornell). Every statistic links to its source. Figures reflect U.S. veterinary patient populations unless otherwise noted, and reported associations between dental and systemic disease are correlations, not proven causation. This page is updated yearly; the next review is scheduled for 2027.
