Why Dental X-Rays Are Important for Cats — Tooth Resorption & Hidden Disease | South Brisbane Vet

Quick Answer

Cats are especially prone to tooth resorption, a painful condition where the tooth structure itself breaks down — and a resorbing tooth can look completely normal above the gumline while there's already a fracture, infection, or fragmented root underneath. Dental X-rays are the only way to see this, confirm how many teeth are affected (resorption is frequently a multi-tooth problem), and justify exactly which teeth need to be extracted. At South Brisbane Vet, full-mouth dental X-rays are included as standard in every cat dental.

Why Cats Need Dental X-Rays More Than People Realise

Cats are particularly prone to tooth resorption, and it's one of the main reasons dental X-rays matter so much in feline dentistry specifically. A resorbing tooth can look entirely normal on the surface, with no obvious crack, discolouration or damage visible above the gumline — while underneath, the tooth may already be fractured, infected, or have roots that have started fragmenting. None of this is visible or able to be felt during a standard oral exam.

Dental X-rays let us see:

Resorptive lesions below the gumline, before any surface damage is visible
Fractures affecting the tooth root, not just the visible crown
Infection or sepsis around the root, even in a tooth with no obvious surface changes
Root fragmentation, where the root has already broken down internally
Whether resorption is affecting just one tooth or multiple teeth — a very common pattern in cats

What We Commonly Find in Practice

In my experience, cats are especially prone to resorptive lesions where a tooth can look completely normal on the surface, but underneath the gums there's already a fracture, infection, or roots that have started fragmenting and causing real pain. X-rays also let us check whether other teeth are affected, because resorption very often isn't limited to just one tooth — it's common to find it in several teeth at once. On top of the diagnostic value, having the X-ray to point to means we can properly justify each extraction we recommend, rather than asking an owner to trust a decision they can't see the evidence for.

Resorption Can Affect More Than One Tooth

Because resorption is often a whole-mouth process rather than an isolated problem, X-rays let us check every tooth, not just the one that prompted the visit. This matters for treatment planning — it means we can identify and treat all affected teeth in a single anaesthetic, rather than your cat needing a second procedure later once another resorbing tooth becomes painful.

X-Rays Justify Every Extraction

Removing a cat's tooth is not a decision we take lightly, and X-rays are what allow us to show you exactly why a particular tooth needs to come out, rather than asking you to take our word for it. It also means every extraction is backed by clear diagnostic evidence — which is exactly the standard of care you should expect from a proper veterinary dental.

Frequently Asked Questions

Are dental X-rays really necessary for cats?

Yes, particularly because cats are so prone to tooth resorption, which is frequently invisible on a standard visual exam. X-rays are the only reliable way to detect it, confirm how many teeth are affected, and plan the right treatment.

What is tooth resorption and why does it need X-rays to find?

Tooth resorption is a common, often painful condition in cats where the tooth's own structure breaks down, usually starting below the gumline. A tooth can look completely normal on the surface while resorption is already well established underneath — X-rays are the only way to see it.

Can resorption affect more than one tooth at a time?

Yes, this is very common in cats. X-rays let us check the whole mouth, not just the tooth that prompted the visit, so any other affected teeth can be treated in the same procedure.

How much does a cat dental with X-rays cost in Brisbane?

At South Brisbane Vet, a standard cat dental including full-mouth X-rays starts from $490. Extractions, if needed, are quoted separately once we can see exactly what's involved.

Will I be shown why a tooth needs to be extracted?

Yes. X-rays let us show you the specific reason behind every extraction we recommend, rather than asking you to take it on trust — that evidence is part of what a proper dental procedure should include.
