Why bad breath is never "just a dog thing": a Tropical Vets guide to pet dental health
Dr. Callan Solari
Bad breath gets treated as a joke more often than it gets treated as a symptom. It's usually the first thing an owner notices, and it's usually the thing we most wish they'd brought in sooner. Dental disease is one of the most common, and most under-treated, conditions we see in practice, in dogs, cats and pocket pets alike.
Why it's easy to miss
Pets are good at hiding pain, and dental pain is no exception. Cats in particular can keep eating, playing and behaving completely normally with a genuinely sore mouth. Signs to watch for include bad breath, a yellow-brown crust on the teeth, bleeding gums, changes in chewing or eating habits, tooth loss and drooling. By the time any of these are obvious, disease is often well established.
It's not just an older pet's problem
Dental disease is more common as pets age, but research suggests that's mostly a lifetime of accumulated disease catching up, not aging itself. Smaller dog breeds and certain cat breeds are especially prone, largely because overcrowded teeth make plaque and tartar harder to manage at home. Around a quarter of dogs present with a fractured tooth at some point, and once the pulp is exposed, infection sets in regardless of age.
Why it matters beyond the mouth
Plaque builds on the teeth, gums become inflamed, and from there bacteria can enter the bloodstream, with the potential to affect the heart, liver and kidneys. That's the real reason dental health gets so much attention from vets: it's rarely contained to the mouth once it's progressed.
Seniors aren't the exception
It's a myth worth retiring: it's never too late to treat oral disease in an older pet. Senior pets are more likely to develop severe gum disease, tooth resorption and oral masses, and often soldier on hiding the pain until it becomes unbearable. Treating it, even late, relieves genuine suffering and can prevent flow-on effects on other organs.
What we actually check for
A full oral assessment requires more than a quick look. Hidden disease below the gumline, root resorption and infected pulp chambers generally can't be seen without general anaesthesia and dental radiographs. That's why a free nurse check is a starting point, not a substitute for a professional clean when one's needed, and why we'll always recommend the next step honestly rather than guess from the outside.
Take the next step
A free dental check with one of our nurses is running throughout August and September. It takes a few minutes, and it's the easiest way to find out whether your pet's mouth needs more than a look.
