Bad breath is usually the first sign your pup or kitty’s mouth needs some attention — but it's rarely the only one. Most dogs and cats are quietly dealing with plaque, sore gums, or hidden tooth trouble well before their pet parent clocks that anything's wrong. If those good-morning kisses have gone from "a bit whiffy" to "actively unpleasant," it's worth a proper look, not just a breath mint.
Here's the bit new pet parents don't always hear: dental disease is one of the most common health issues vets see in dogs and cats, full stop. That's not us trying to worry you — it's genuinely just how common it is. The good news? It's also one of the easiest conditions to catch early, once you know what you're looking — and sniffing — for.
Dental disease starts small. Plaque builds up on the teeth, hardens into tartar, and starts irritating the gums. Left alone, that can progress to gingivitis (red, inflamed gums), then periodontal disease, which affects the structures holding the teeth in place. In the more advanced stages, it can mean tooth loss, painful infections, and — because the mouth is so close to the bloodstream — bacteria travelling to organs like the kidneys, liver, or heart.
Written out like that, it sounds alarming, and yes, it can get serious. But it's also gradual. That means there's usually a good window where a simple scale and polish at the vet sorts everything out, long before it becomes anything bigger.
This is where a lot of new pet parents get caught out — dogs and cats are experts at hiding discomfort, so the early signs can be subtle. Keep an eye (and a nose) out for:
Cats are especially good at masking pain, so even something as small as "she's eating a little slower lately" is worth mentioning to your vet. It might be nothing. It might be the first sign her mouth's bothering her.
Nobody expects a dog's breath to smell like roses, a little "just had breakfast" whiff is completely normal. But a persistent, noticeably unpleasant smell is your pet's mouth telling you plaque and bacteria have moved in and made themselves at home. It's one of the easiest signs to brush off (pun very much intended), but it's also one of the most reliable early warnings dental disease gives you.
More than most new pet parents expect, yes. Left untreated, dental disease isn't just a mouth problem — it can genuinely affect your pet's overall health and comfort, and vet bills have a way of growing right alongside it. According to PetSure claims data for FY24–25, the average dental illness claim for cats sat at $840, with the highest single treatment cost that year reaching close to $6,000. What often starts as bad breath can escalate into extractions, anaesthetic, x-rays, and infection management — which is exactly why catching it early matters, both for your fur baby's comfort and your bank balance.
Every pet benefits from a bit of dental TLC, but if your fur baby ticks one of these boxes, it's worth being a little more proactive.
Starting early can make a real difference. Puppies and kittens who get comfortable having their mouths handled tend to be much easier (and calmer) patients for dental care down the track.
It depends on what kind of treatment your pet needs. Dental disease — including infections, abscesses, or a tooth that needs to come out — isn't covered under your standard illness cover. It's only claimable if you've added Booster Care, and you'll need to have served its 6-month waiting period before a claim can be made. So if dental health matters to you, it may be worth considering Booster Care and getting that waiting period ticked off well before you actually need it, not after.
Where it gets less straightforward is prevention. A routine scale and polish — the kind of clean your vet might suggest as a checkup, before anything's actually gone wrong — usually isn't included in standard cover. Some policies let you add this on separately if it's something you want built into your plan.
Honestly, the best way to know exactly where you stand is to check your own PDS or just ask us directly — dental cover is one of those areas where the details genuinely vary, and we'd rather you knew for certain than guessed.
What's the first sign of dental disease in pets? Bad breath is usually the earliest noticeable sign, often followed by visible tartar buildup, red or swollen gums, and changes in eating habits.
Can dental disease in pets be serious? Yes. Left untreated, it can progress to painful infections, tooth loss, and in some cases allow bacteria to spread to organs like the kidneys, liver, or heart.
How much does pet dental treatment cost in Australia? Costs vary depending on severity. PetSure claims data for FY24–25 puts the average dental illness claim for cats at $840, with the highest recorded treatment cost that year reaching close to $6,000.
