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

By Dr Duncan Houston

Bringing your dog home after dental surgery and discovering they have only their four pointed canine teeth left can be a shock. You might wonder why so many teeth needed removing, whether the remaining teeth are enough and how your dog will manage meals.

The explanation should come from your dog’s dental findings. The pattern of missing teeth alone cannot tell you the diagnosis.

Quick Answer

A common reason for extensive tooth removal in dogs is advanced periodontal disease, which damages the tissues and bone supporting the teeth. Your vet may keep the canines if they are healthy or can be treated successfully. There is no standard rule that dogs should have every tooth except their canines removed; each tooth needs an individual assessment.

Why would a dog need so many teeth removed?

Advanced periodontal disease

Periodontal disease starts with plaque and inflammation around the gums. As it progresses, the supporting tissues and bone can deteriorate, leaving teeth loose, painful or affected by infection.

If many teeth have lost substantial support, cleaning alone may no longer be enough. Removing teeth with a poor prognosis allows those sites to heal and removes a source of ongoing discomfort.

Much of this damage occurs below the gumline. A tooth that looks reasonably clean from the outside can still have serious disease around its roots.

Broken or diseased teeth

Some dogs also have fractured teeth or disease inside the tooth. Depending on the damage, treatment may involve extraction or a procedure such as root canal treatment.

A veterinary dentist can assess whether a particular tooth can be saved. Keeping a tooth is worthwhile when it can remain comfortable and functional with appropriate treatment and follow-up.

Chronic inflammation and ulcers

Dogs can develop painful inflammation and ulcers in the lining of the mouth, including canine chronic ulcerative stomatitis.

However, this does not automatically mean they need most or all their teeth removed. Treatment depends on the diagnosis, accompanying dental disease and response to earlier care.

A study of 42 dogs with a particular pattern of chronic oral inflammation found that many improved after treatment of periodontal disease without full-mouth extractions. Some dogs need additional extractions or medical treatment, and specialist advice can be helpful when inflammation persists.

Why were the canine teeth left behind?

The canine teeth are the four long, pointed teeth near the front of the mouth.

Your vet may have retained them because examination, gum probing and dental X-rays showed that they had enough healthy support and a reasonable outlook.

Healthy canines do not need removing simply because neighbouring teeth are diseased. Equally, being a canine tooth does not protect it from disease or make it essential to keep at any cost.

If a remaining canine has significant disease, your vet should explain its treatment plan. Depending on the findings, that might involve periodontal treatment, root canal treatment, extraction or referral.

If teeth remain, the procedure was not technically a full-mouth extraction. Asking for the dental chart will help clarify exactly what was removed.

What should I ask the vet?

Ask your vet to talk you through the findings in plain language:

• What was the main diagnosis?

• Which teeth were removed, and why?

• What did the dental X-rays show?

• Were the canines healthy, or do they need further treatment?

• Is treatment complete, or is another procedure planned?

• When should healing and the remaining teeth be checked?

Dental X-rays help assess structures that cannot be judged by looking at the visible tooth alone. For complicated disease, multiple extractions or uncertainty about treatment options, a veterinary dental specialist can provide further assessment.

Can my dog still eat with only a few teeth?

Many dogs adapt very well once their mouth has healed. Having fewer teeth does not automatically mean a poor quality of life.

In an owner survey covering 55 dogs that had undergone full-mouth extractions, approximately 93% were reported to have improved oral comfort afterwards. Just over half ate the same diet as before surgery.

That was a relatively small survey from one referral practice, so it cannot predict an individual dog’s recovery. It does show that losing teeth can be compatible with comfortable eating and a good daily life.

Your dog may need softer food, a different texture or a little time to adjust. The best choice is a nutritionally complete diet they can eat comfortably, guided by their vet.

How to help your dog recover

Follow the pain relief plan

Give prescribed pain medication exactly as directed. If your dog resists medication, contact the clinic for another way to administer it.

Not eating, rubbing at the mouth or seeming persistently uncomfortable warrants a call to the treating team. Do not assume these signs are simply something your dog must put up with after surgery.

Offer the recommended food texture

After extractions, vets commonly recommend wet food or thoroughly softened kibble for around 10 to 14 days. Your dog’s surgeon may recommend a different period depending on the procedure.

Follow their feeding instructions and monitor how much your dog actually eats. Licking gravy while leaving most of the meal is different from eating an adequate amount.

Protect the healing mouth

Keep chew toys, hard treats, bones and tug games away during recovery. Even if your dog seems enthusiastic, chewing or pulling can disturb healing tissues.

Do not force the mouth open, pull at stitches or lift the lips to inspect surgical wounds unless the surgeon has shown you what is safe. Ask when brushing can restart. A recheck at around two weeks is often used to assess healing before restrictions are lifted.

When should I contact the vet after surgery?

Follow your clinic’s discharge instructions, including any advice specific to your dog’s other medical conditions.

What you notice	What to do
Mild tiredness on the first evening, with your dog responsive and becoming brighter	Allow quiet rest and follow the discharge plan.
Refusing food the next morning, struggling to drink, repeated vomiting or obvious discomfort	Contact the treating clinic that day, sooner if your dog seems unwell.
Increasing facial swelling, discharge, worsening mouth odour or persistent bleeding	Arrange a prompt veterinary assessment.
Heavy bleeding, difficulty breathing, collapse or inability to wake normally	Seek emergency veterinary care immediately.

Pain that is worsening or an appetite that is not recovering deserves attention. Do not wait for the routine recheck if you are concerned.

Looking after the remaining teeth

The canines still need ongoing care. Once your vet confirms the mouth has healed, introduce or resume gentle daily brushing with dog toothpaste, following their advice.

Continue regular dental checks. Avoid very hard chewing objects, such as bones and antlers, which can fracture the remaining teeth. Ask your vet which dental products and enrichment activities suit your dog’s mouth.

Frequently Asked Questions

Could the canines need removing later?

Yes, if they develop disease that cannot be managed successfully. Keeping them now means they were considered worth retaining at that assessment, not that they will remain healthy indefinitely. Regular examinations help identify changes.

My dog was still eating before surgery. Were the extractions really necessary?

Dogs can continue eating despite dental pain. Appetite alone cannot show whether a tooth is healthy. The decision should be based on the examination, gum measurements and dental X-rays, with your vet explaining those findings.

Does needing so many extractions mean I failed my dog?

Dental health is influenced by factors including genetics, age, other health conditions and oral care. Smaller dogs are particularly prone to periodontal disease. Home care matters, but the useful next step is a practical plan for keeping your dog comfortable and protecting the remaining teeth.

Should every dog receive antibiotics after dental extractions?

No. Antibiotics are assessed individually and are not routinely needed after every extraction. Removing diseased tissue and providing appropriate pain relief are central parts of treatment. Give antibiotics only if prescribed for your dog, and follow the vet’s directions.

If you are unsure why your dog’s teeth were removed, start by asking the treating clinic to explain the dental chart and X-rays. ASK A VET™ can help you understand the terminology and prepare questions about recovery and ongoing care. If your dog is painful, not eating or developing swelling, contact their treating vet promptly so their mouth can be examined.
