A Breath of Fresh Air: Understanding Dental Disease in Dogs and Cats

July 15, 2025

Oral health matters at Brookville Veterinary Hospital

Your dog’s wagging tail and your cat’s purr are welcome parts of your day—but their breath? Not so much. While “dog breath” might seem normal, persistent bad breath is often a sign of dental disease, a silent condition that affects more than 70% of dogs and cats over age three.

At Brookville Veterinary Hospital, we take pet dental health seriously—not just for fresh breath, but because oral disease can impact your pet’s entire body. Let’s look at what causes dental disease, how to spot it early, and what you can do to keep those teeth clean and those kisses healthy.

What Is Dental Disease?

Dental disease in pets typically begins as plaque, a sticky film of bacteria on the teeth. If not removed, plaque hardens into tartar, which builds up along the gumline. Over time, this leads to:

Gingivitis (gum inflammation)
Periodontal disease (infection and breakdown of tooth support structures)
Tooth loss
Pain and difficulty eating
Bacteria entering the bloodstream—potentially damaging the heart, kidneys, and liver

In short: untreated dental disease isn’t just a mouth problem. It’s a whole-body health risk.

What Causes Dental Disease in Dogs and Cats?

The main culprits are:

Lack of at-home dental care (like brushing or dental chews)
Breed predisposition (small dogs and flat-faced breeds are more at risk)
Diet (sticky, carb-heavy foods can promote plaque)
Age—older pets are more likely to have built-up tartar and gum recession
Poor genetics or retained baby teeth in some breeds

Cats may also develop resorptive lesions, a painful condition where the tooth breaks down from the inside. These require careful veterinary evaluation.

Common Signs of Dental Disease in Pets

Bad breath (halitosis)
Red, swollen, or bleeding gums
Visible yellow or brown tartar
Loose or missing teeth
Pawing at the mouth or face
Reluctance to eat or chew toys
Drooling, especially if it’s tinged with blood
Facial swelling or sensitivity near the jaw

Many pets show no outward signs until the disease is advanced, which is why routine dental checks are so important.

Dental Cleanings: What Happens During a Vet Visit?

At Brookville Veterinary Hospital, dental cleanings are performed under anesthesia for safety and thoroughness. Here’s what to expect:

Pre-anesthetic bloodwork to assess overall health
An oral exam and full-mouth digital dental X-rays
Scaling to remove plaque and tartar above and below the gumline
Polishing to smooth enamel and prevent future buildup
Tooth extractions if severe damage or infection is found
Pain relief and antibiotics, if needed
At-home care instructions for recovery and continued prevention

We monitor your pet closely throughout the entire procedure and provide supportive care for a smooth, safe experience.

Why Anesthesia Is Necessary

While “awake” cleanings are offered by some groomers or online services, they are not recommended. Only under anesthesia can we:

Access below the gumline
Take accurate X-rays
Thoroughly examine each tooth
Remove deeply seated tartar without causing pain

Anesthetic dental procedures are the gold standard for safety and effectiveness.

Dental Home Care: What You Can Do

Daily brushing is the best defense against plaque—but even 2–3 times a week can make a difference. Use:

A pet-safe toothbrush or finger brush
Veterinary-approved enzymatic toothpaste (never use human toothpaste)
Positive reinforcement to build tolerance over time

If brushing isn’t an option, try:

Dental chews approved by the Veterinary Oral Health Council (VOHC)
Dental rinses or water additives
Prescription dental diets
Toys designed to promote mechanical cleaning

Your vet can help you choose the best option for your pet’s personality and needs.

The Link Between Oral and Systemic Health

Dental disease doesn’t just stay in the mouth. In advanced cases, oral bacteria can enter the bloodstream and travel to major organs, contributing to:

Heart valve infections (endocarditis)
Kidney and liver dysfunction
Worsening of pre-existing conditions like diabetes or arthritis

That’s why keeping your pet’s mouth healthy is one of the most important things you can do for their long-term wellness.

How Often Do Pets Need a Dental Cleaning?

It varies by age, breed, and home care. As a general rule:

Most dogs and cats benefit from professional dental cleanings once a year
Small breeds and brachycephalic (flat-faced) pets may need cleanings every 6–9 months
Senior pets may require more frequent monitoring

We’ll evaluate your pet’s teeth during their wellness exams and let you know when it’s time.
