Hidden Dental Pain in Cats: Midnight Battles Tooth Resorption

A Routine Health Check Uncovered Something More

Midnight is a beautiful 7-year-old cat who came to see us for her annual health check and vaccination.

During this appointment, we found her lower left canine tooth was severely diseased, with advanced periodontal disease, infection around the tooth and heavy calculus build-up affecting her other teeth.

To properly assess the extent of her condition, we recommended a dental procedure under general anaesthetic that would include a thorough oral examination, dental X-rays, cleaning her teeth and treating the painful tooth.

“Cats are incredibly good at hiding dental pain, even when they’re living with significant oral disease.”

What We Found During Her Dental Procedure

Once Midnight was under anaesthetic, it was clear just how painful her lower left canine tooth was. When the tooth was gently probed, she showed a teeth-chattering pain response, something cats can do when a sore tooth is touched, even if they’ve shown little or no sign of discomfort at home.

Dental X-rays revealed infection affecting the bone and surrounding tissues, with the tooth being pushed out of its socket by advanced periodontal disease and external root resorption. The tooth was extracted, the infected tissue was carefully removed, and Midnight went home with antibiotics to help clear the infection.

Tooth Resorption Was Affecting More Than One Tooth

While examining Midnight’s mouth and reviewing her dental X-rays, we also discovered three additional teeth affected by Type 1 tooth resorption.

Tooth resorption is one of the most common and painful dental conditions seen in cats. It gradually destroys the enamel, dentine and sometimes the pulp cavity. Some affected teeth develop visible holes or defects, while others look almost normal despite being painful.

The exact cause is still unknown, but it is estimated to affect up to 70% of cats over five years of age. Unlike a cavity in people, tooth resorption can’t be repaired with a filling. Once the tooth becomes painful or structurally damaged, extraction is the only effective treatment.

“Dental X-rays are essential for identifying the full extent of tooth resorption and planning the most appropriate treatment.”

Back to Enjoying Her Food

All of Midnight’s diseased teeth were removed, and her remaining teeth were professionally cleaned during the procedure.

At her post-operative check, her extraction sites had healed beautifully, and she was already back to happily eating her kibble.

Why Regular Dental Checks Are So Important for Cats

Cats often hide pain incredibly well, which means serious dental disease can develop long before there are any obvious signs at home. Regular health checks, dental examinations and dental X-rays allow us to identify painful conditions like tooth resorption early and treat them before they become even more advanced.

If you’ve noticed changes in your cat’s breath, eating habits or comfort, or it’s been a while since their last dental assessment, our veterinary team is always happy to discuss the options and help you decide what’s right for your cat.

Frequently Asked Questions

How can cats have painful dental disease without showing obvious signs?

Cats instinctively hide pain, so many continue eating and behaving normally despite significant dental disease. Midnight’s case is a good example of why regular health checks and dental examinations are so important for identifying painful conditions early.

What is tooth resorption in cats?

Tooth resorption is a common and painful dental condition where the tooth gradually breaks down over time. It can affect the enamel, dentine and pulp cavity, and some affected teeth show very few visible signs despite causing significant discomfort.

Can tooth resorption in cats be treated without extracting the tooth?

Unfortunately not. Unlike a cavity in people, tooth resorption cannot be repaired with a filling. Once a tooth has become painful or structurally damaged, extraction is the only effective treatment.

Why are dental X-rays important during a cat's dental procedure?

Dental X-rays allow vets to assess the structures below the gumline that cannot be seen during a visual examination alone. In Midnight’s case, they revealed three additional teeth affected by Type 1 tooth resorption as well as the full extent of the disease affecting her canine tooth.

What signs could mean my cat needs a dental assessment?

Changes in breath, eating habits or overall comfort can all indicate an underlying dental problem. However, because cats often hide oral pain, many painful conditions are only discovered during routine health checks and dental examinations.
