“Dog breath” is so common that most owners assume it’s just part of having a dog. Here’s the truth from the exam room: persistent bad breath is almost never normal. It’s usually the first — and sometimes the only — sign of dental disease, the single most common health problem we diagnose at our clinic. By age three, the majority of dogs and cats already have some degree of periodontal disease, and most of it goes unnoticed because pets are remarkably good at hiding mouth pain.

At Sanctuary Veterinary Hospital in Sage Hill, NW Calgary, dental care is one of the most impactful services we provide — because treating a painful mouth often transforms a pet’s energy, appetite and mood in ways their owners never expected. Here’s what every Calgary pet owner should know.

How Dental Disease Develops (and Why It’s More Than Just Teeth)

It starts quietly. Plaque — a soft film of bacteria — builds on the teeth within hours of eating. Within days, minerals in saliva harden it into tartar, which you can’t brush off. Bacteria then work their way under the gumline, where the real damage happens: inflamed gums, infected tooth roots, and destruction of the bone holding the teeth in place. This below-the-gumline disease is invisible from the outside, which is why a mouth can look “okay” while hiding painful, infected roots.

And it doesn’t stop at the mouth. Bacteria from infected gums enter the bloodstream and place ongoing strain on the heart, kidneys and liver. Dental disease isn’t a cosmetic issue — it’s a whole-body health issue, and it’s one of the most preventable ones in veterinary medicine.

Signs Your Dog or Cat Has Dental Disease

• Persistent bad breath — the earliest and most reliable sign
• Yellow-brown tartar on the teeth, or red, bleeding gums
• Dropping food, chewing on one side, or swallowing kibble whole
• Pawing at the mouth or rubbing the face
• Drooling, sometimes blood-tinged
• Reluctance to play with toys or be touched around the head
• In cats: hiding more, grooming less, or going off food

The most important sign is no sign at all. Dogs and cats instinctively hide pain. We routinely find severely diseased teeth in pets who are “eating fine” — because the alternative to eating with a painful mouth is not eating. Many owners only realize how much pain their pet was in when they see the change after treatment.

What a Professional Dental Cleaning (COHAT) Actually Involves

A proper veterinary dental procedure is called a COHAT — Comprehensive Oral Health Assessment and Treatment — and it’s much more than a “teeth cleaning”:

• Pre-anesthetic exam and blood screening to confirm your pet can safely undergo anesthesia — the same careful protocol we follow for any surgical procedure
• General anesthesia with continuous monitoring, so we can work safely below the gumline where disease actually lives
• Full-mouth dental X-rays — essential, because around two-thirds of each tooth sits below the gumline, and root infections, abscesses and bone loss are invisible without imaging
• Ultrasonic scaling above and below the gumline, followed by polishing to slow future plaque buildup
• Tooth-by-tooth charting and probing, exactly like your own dental check-up
• Extractions or treatment where needed, with local nerve blocks and pain management — removing a diseased tooth ends the pain; leaving it prolongs it

Why We Don’t Recommend “Anesthesia-Free” Dental Cleaning

You may have seen anesthesia-free dental scaling offered at groomers or pet stores. We understand the appeal — anesthesia sounds scarier than scraping. But cosmetic scaling on an awake pet can only clean the visible part of the tooth. It cannot clean below the gumline, take X-rays, or find painful disease — so the teeth look whiter while infection continues underneath. It can also create a false sense of security that delays real treatment. Modern veterinary anesthesia, with pre-screening and continuous monitoring, is very safe — and it’s the only way to actually treat dental disease. Our surgical FAQs cover our anesthesia safety protocols in detail.

Dental Care at Home: What Actually Works

Between professional cleanings, home care makes a huge difference in how fast plaque returns:

• Brushing is the gold standard. Even 3–4 times a week significantly slows plaque. Use a pet toothbrush or finger brush with pet-specific toothpaste — never human toothpaste, which contains ingredients pets shouldn’t swallow. Start slow: a few seconds, lots of praise, build up over weeks.
• Choose products with the VOHC seal. The Veterinary Oral Health Council certifies dental diets, chews and water additives that are actually proven to reduce plaque and tartar. Many popular products have no evidence behind them — ask us what we recommend for your pet.
• Skip the hard stuff. Antlers, bones, hooves and hard nylon chews crack teeth — fractured teeth are one of the most common painful problems we treat. A good rule: if you can’t dent it with your thumbnail, it’s too hard.
• Don’t forget the cat. Cats develop a uniquely painful condition called tooth resorption, where teeth dissolve from within. It affects a large share of adult cats and is only detectable with dental X-rays.

When Should My Pet Have a Dental Check?

Every pet should have their mouth assessed at their annual wellness exam — we grade dental health at every visit. How often a pet needs a professional cleaning varies widely: small breeds (Yorkies, Dachshunds, Chihuahuas), flat-faced breeds and cats with crowded teeth often need them more frequently, while some large-breed dogs go years between cleanings. The key is acting early — treating mild dental disease is simpler, cheaper and far more comfortable for your pet than waiting until teeth need extraction.

Frequently Asked Questions

Is my pet too old for a dental cleaning?

Age itself is not a disease, and senior pets are often the ones suffering most from dental pain. With pre-anesthetic blood work — and additional screening like ECG or X-rays where appropriate — many senior dogs and cats safely undergo dental procedures and enjoy a dramatic improvement in comfort afterward. We assess every pet individually.

Will my pet be able to eat after extractions?

Yes — usually better than before. Pets eat more comfortably without painful, infected teeth than with them. Even pets who have many teeth removed adapt quickly, often returning to dry food after healing. Owners frequently tell us their pet acts years younger after a dental procedure.

Do dental chews replace brushing or professional cleanings?

No. VOHC-approved chews and diets help slow plaque between cleanings, but nothing replaces brushing for daily control, and no home care can remove tartar or treat disease below the gumline. Think of chews as a supplement, brushing as maintenance, and the COHAT as the actual treatment.

How much does a dog or cat dental cleaning cost in Calgary?

It depends on your pet’s size, the severity of disease, and whether extractions or other treatments are needed — which is why we examine your pet first and provide an estimate before any procedure. Call us at (403) 295-0305 to book a dental assessment and get a tailored quote.
