When should you see a veterinary dentist?

Early symptoms that owners often ignore

Persistent bad breath is one of the most common “first warning bells”. In the great majority of cases halitosis has a dental source: bacterial plaque, gingivitis, periodontitis or a diseased tooth. A temporary smell after a meal is normal; a smell that does not go away for weeks is a reason for an examination.

A yellowish or brown film near the gumline, visible tartar, blood on toys or in the bowl after eating — these are typical signs of active inflammation. A pet may eat more slowly, prefer soft food, chatter its jaw or “drop” food from its mouth.

• Persistent bad breath lasting more than a few days
• Visible tartar, a darkened tooth or a loose tooth
• Blood on toys, bones or in the bowl after eating
• Drooling, especially in cats

Changes in behaviour during meals and play

Refusing dry food while still keen on soft food is a classic sign of pain when biting hard food. A pet may chew on only one side of the mouth, flinch while eating, choose smaller pieces of kibble or soak its food.

In cats these changes are especially subtle: a cat may eat smaller portions but more often, avoid having its face touched, play less and groom less — and still look “almost normal”. That is why I always ask owners not only about appetite but also about exactly how the pet eats.

Why a pet may keep eating even when it hurts

In my practice I regularly see patients with marked disease of the mouth who keep eating. This does not mean there is no pain — it means the animal adapts: it chooses soft food, chews on one side, and eats faster or slower to minimise discomfort.

The owner notices only a “slight smell” or “a little blood on a toy” — and puts the visit off. I advise taking such small things seriously: they often appear months before a pet refuses food.

I explain why a tooth can hurt even when nothing shows on the outside, and how the mouth is linked to the rest of the body, in How a dog’s and cat’s mouth works.

What the dentist does at the appointment

At the first consultation I assess the teeth, gums, bite, the lining of the mouth and the overall condition of the oral cavity as far as that is possible in a conscious animal. This gives a general orientation, but not the full picture.

Where clinically indicated, I plan a full COHAT examination under anaesthesia with dental X-rays. That is where hidden problems show up: periodontal pockets, bone loss, root infections, tooth resorption in cats, root fractures.

Preventive check-ups without complaints

Even without obvious symptoms, a regular dental check-up makes sense. In many adult pets I find early gingivitis or tartar under the gums that the owner never suspected. How often depends on age, breed, bite, home care and medical history.

For puppies and kittens there is an extra reason: assessing the bite and the baby teeth. Retained baby canines, double teeth and teeth in the wrong position are better corrected early.

What to do if you notice warning signs

Do not wait for the symptoms to “go away on their own”. Do not give antibiotics or painkillers without a vet's advice — they can temporarily mask the picture. Book a consultation, describe the changes in behaviour at mealtimes and bring a list of any medication your pet is taking.

If there are acute signs — swelling of the face, refusing water, lethargy, bleeding that will not stop — your pet needs to be seen as soon as possible.
