Why Did the Vet Remove All My Cat’s Teeth Except the Canines?

By Dr Duncan Houston

Hearing that your cat needs most of their teeth removed can be confronting. Seeing just the four long canine teeth left afterwards naturally raises another question: why keep those ones?

This can be a deliberate treatment decision when the remaining teeth and surrounding tissues are healthy. The explanation depends on the diagnosis, the examination and the dental X-rays, so the extraction pattern alone cannot tell you exactly what happened.

Quick Answer

Vets may remove most teeth to treat stomatitis, tooth resorption or advanced periodontal disease. Healthy canines may be retained if their surrounding tissues are unaffected and follow-up is planned. Diseased canines should not be kept just because they are the large “fang” teeth.

Ask your vet which condition was treated and why each remaining tooth was considered suitable to keep.

A common reason: feline chronic gingivostomatitis

Feline chronic gingivostomatitis, often shortened to stomatitis, causes severe inflammation of the mouth's soft tissues. It can extend well beyond the gum margins, including into the back of the mouth.

The disease involves an abnormal immune response to material in the mouth, including dental plaque. Its development is complex, and it is not simply a case of dirty teeth.

Affected cats may drool, have unpleasant breath, struggle to eat, lose weight or approach their food and then back away. Some teeth can look relatively normal despite significant inflammation around them.

Why remove teeth when the inflammation is in the gums?

Teeth provide surfaces where plaque accumulates. Removing selected teeth, or sometimes all teeth, reduces the plaque-retaining surfaces that contribute to ongoing inflammation.

That is why extraction can help even when an individual tooth does not appear rotten or broken. A routine scale and polish may provide only temporary improvement because plaque forms again.

The treatment goal is a comfortable, functional mouth.

Why would the vet leave the canines?

The canines are the four long, pointed teeth at the front of the mouth.

Current feline dental guidelines support retaining healthy front teeth in selected stomatitis cases when there is no associated inflammation and regular follow-up is possible.

Inflammation around the canines, or disease within them, may instead make extraction necessary. Their health and the overall disease pattern determine the decision.

Is this the same as a caudal-mouth extraction?

Not exactly.

A caudal-mouth extraction removes the premolars and molars, which are the teeth towards the sides and back of the mouth. Healthy canines and the small front incisors may remain.

If only the four canines are left, the incisors have also been removed or were already absent. Your cat's dental chart can clarify precisely which teeth were extracted and which were missing beforehand.

What other conditions could explain so many extractions?

Tooth resorption

Tooth resorption progressively destroys a tooth's structure. It can affect several teeth and extend beneath the gum, where an owner cannot see it.

Cats may continue eating despite painful lesions, sometimes swallowing food without chewing or favouring one side. Dental X-rays help identify the extent of the damage.

A cat with numerous affected teeth may require extensive treatment while unaffected canines are retained. This is a different process from stomatitis, although both conditions can occur together.

Advanced periodontal disease

Periodontal disease damages the tissues and bone that support the teeth. Severely affected teeth may become loose, painful or unable to function comfortably.

When this damage is widespread, many teeth may need removal. Teeth with healthy support can sometimes remain. The decision depends on assessment of each tooth, including the structures beneath the gum.

How can I check why this was done?

Ask the clinic to talk you through the dental chart, before-and-after X-rays and treatment plan.

Useful questions include:

• Was the main diagnosis stomatitis, tooth resorption, periodontal disease or a combination?

• Were the canines and the tissues around them healthy?

• Were all intended extractions completed, or is another procedure planned?

• What findings would mean the remaining teeth need treatment?

• When should the mouth be rechecked?

Dental X-rays reveal problems that are not visible from the outside, including root disease and bone loss. They also help assess extraction sites. If the explanation remains unclear or your cat continues to struggle, a veterinary dental specialist can review the findings.

Can my cat eat with only their canines?

Yes. Many cats eat well with very few teeth, and even cats with no teeth can manage a suitable complete diet.

Once the mouth has healed, some cats eat wet food, some eat dry food and others manage both. The best texture depends on comfort, preference and any other health needs.

During surgical recovery, follow the vet's specific feeding instructions. A soft diet is commonly advised for about 7 to 14 days, sometimes longer after extensive surgery. Avoid hard treats and toys that could disturb the sutures until the vet clears them.

Do not test recovery by offering something hard to see whether your cat can chew it.

Will removing the teeth cure stomatitis?

Extractions often help substantially, but they do not guarantee a complete cure.

In a study of 95 cats treated with extractions for stomatitis, approximately 39% improved substantially and 28% had complete resolution. Many cats with a favourable outcome still needed medication for a period after surgery.

Healing of the surgical sites and improvement of the underlying inflammation are different processes. A mouth can have healed incisions while still needing treatment for stomatitis.

Persistent pain warrants reassessment. Possible explanations include ongoing inflammation, disease around retained teeth, retained diseased root fragments or a healing complication. Unusual lesions may require further investigation, including biopsy.

What should I do during recovery?

1. Give prescribed pain relief as directed. Contact the clinic if administering it is difficult or your cat still seems sore.

2. Follow the feeding plan. Offer manageable portions of the recommended food and track how much is actually eaten.

3. Protect the mouth. Avoid hard chewing, pulling at the lips or repeatedly opening the mouth to inspect the wounds.

4. Attend the recheck. An examination around two weeks is common, but your vet may want to see your cat sooner.

5. Record changes. Note appetite, drinking, grooming, drooling, activity and comfort while eating.

Do not add human painkillers or change medication doses without veterinary advice.

When should I contact the vet urgently?

What you notice	What to do
Eating manageable meals, comfortable on medication and gradually returning to normal behaviour	Continue the recovery plan and attend the scheduled recheck.
Refusing food, worsening pain, new swelling, persistent bleeding or increasing drooling	Contact the treating clinic the same day. Do not wait several days for appetite to return.
Difficulty breathing, collapse or heavy bleeding that continues	Seek emergency veterinary care immediately.

Painful eating should not be dismissed as your cat simply “getting used to having fewer teeth”.

Common mistakes to avoid

• Assuming eating means there is no pain. Cats can adapt their eating behaviour around dental discomfort.

• Assuming retained canines can never become diseased. They still need monitoring.

• Brushing a sore or newly operated mouth. Wait for the treating vet's instructions.

• Expecting antibiotics alone to resolve stomatitis. Medication may be part of the plan, but repeated antibiotics do not replace appropriate dental treatment.

• Skipping rechecks because the teeth are gone. Soft-tissue inflammation can persist.

Frequently asked questions

Will the canines need to be removed later?

Possibly, if disease or inflammation persists or develops. Further treatment does not automatically mean the original decision to retain healthy teeth was wrong.

Was this caused by not brushing my cat's teeth?

Not necessarily. Home dental care can reduce plaque and help prevent periodontal disease, but stomatitis and tooth resorption have more complex causes. Their occurrence does not, by itself, show that an owner failed to care for their cat.

Should I brush the remaining teeth?

Once healing is complete, ask your vet whether brushing is appropriate. Healthy remaining teeth benefit from plaque control, but brushing an actively inflamed mouth can be painful. Never force it.

If you are unsure why your cat's canines were retained, start by asking the treating clinic to explain the dental findings and follow-up plan. ASK A VET™ can help you understand the terminology and organise your questions, while an in-person examination is needed if your cat remains uncomfortable.
