If your dog or cat has breath that could clear a room, it is tempting to write it off as a normal part of pet ownership. It is not. That smell is usually the first sign of dental disease, and it is the most common health problem vets see in Australian pets. By the age of three, around 80% of dogs and 70% of cats already have some degree of it, according to the RSPCA. The good news is that it is largely preventable, and a few simple habits can save your pet a lot of discomfort and save you a hefty vet bill down the track.
What dental disease actually is
Dental disease in pets almost always starts the same way it does in people. A sticky film of bacteria called plaque builds up on the teeth. If it is not removed, it hardens into tartar, the yellow-brown crust you can sometimes see along the gum line. From there the gums become inflamed (gingivitis), and over time the infection works its way under the gum to damage the bone and tissue holding the teeth in place. That advanced stage is called periodontal disease, and it can lead to painful, loose teeth that need to be removed.
It is more than a mouth problem. Vets generally agree that the ongoing infection can place extra strain on the heart, liver and kidneys, which is one reason dental care is taken so seriously. The frustrating part is that pets are very good at hiding mouth pain, so many keep eating normally even when their gums are sore.
Warning signs to watch for
You do not need to be a vet to spot the early clues. Lift your pet’s lip every week or two and take a quick look. Book a check-up if you notice any of the following:
- Persistent bad breath that does not go away
- Yellow or brown buildup along the gum line
- Red, swollen or bleeding gums
- Dropping food, chewing on one side, or going off harder foods
- Pawing at the mouth or face rubbing
- Excess drooling or blood-tinged saliva
- Loose, broken or missing teeth
Cats can be especially subtle. A cat that has started favouring soft food or grooming less may have a sore mouth rather than simply being fussy. When in doubt, have a vet take a look.
How to keep your pet’s teeth healthy
Prevention is far cheaper and kinder than treatment. Here is what actually works, roughly in order of effectiveness.
Brushing is the gold standard
Daily brushing is the single most effective thing you can do at home. Use a pet-specific toothpaste, never human toothpaste, as ingredients like fluoride and xylitol can be toxic to animals. Start slowly: let your pet lick a little paste off your finger first, then introduce a soft pet toothbrush or a finger brush over a week or two. Keep sessions short and positive. The RSPCA notes that the younger you start, the easier it tends to be, but plenty of adult pets learn to tolerate it with patience.
Dental chews, diets and toys
These are a useful backup, not a replacement for brushing. Some prescription dental diets and approved dental chews are designed to reduce plaque and tartar through their texture. Look for products carrying the Veterinary Oral Health Council (VOHC) seal, which means they have been independently tested. Avoid very hard items such as bones, antlers and hooves, which are a common cause of cracked teeth.
Annual vet checks and professional cleans
Even with great home care, most pets need a professional scale and polish at some point. This is done under general anaesthetic so the vet can clean below the gum line and take dental X-rays, which is where most disease hides. It sounds daunting, but a modern dental procedure with proper monitoring is routine, and addressing problems early usually means fewer extractions and a lower cost than waiting until teeth are beyond saving.
Frequently asked questions
How much does a dog or cat dental clean cost in Australia?
Costs vary widely depending on your location, the clinic and how much work is needed, but a routine scale and polish often runs from a few hundred dollars, rising if extractions or X-rays are required. Ask your vet for a written estimate, and check whether your pet insurance includes dental, as many policies only cover dental from accidents rather than disease.
Can I just use dental treats instead of brushing?
Dental treats can help reduce plaque, but on their own they are not enough to prevent disease. Think of them as a helpful extra alongside brushing and regular vet checks, not a substitute. Choose VOHC-approved products and factor the kilojoules into your pet’s daily food to avoid weight gain.
Is bad breath in pets ever normal?
Genuinely fresh breath is not expected, but breath that is strongly offensive is a red flag rather than something to ignore. Sudden changes in smell, especially a sweet or unusually foul odour, are worth a vet visit as they can point to dental or other health issues.
Key takeaways
- Dental disease affects most pets by age three and is largely preventable
- Bad breath, discoloured teeth and red gums are early warning signs
- Daily brushing with pet toothpaste is the most effective home care
- Use VOHC-approved chews and diets as a backup, not a replacement
- Book an annual dental check; professional cleans catch what you cannot see
