A root canal for a dog costs roughly $1,500 to $4,000 per tooth with a board-certified veterinary dentist, including anaesthesia, dental radiographs and the procedure. A crown, if recommended, adds $1,000 to $2,000.
Extraction of the same tooth typically costs $800 to $2,000. That comparison is where most owners start, and it is the wrong place to start.
The thing to settle first: doing nothing is not an option
If your dog has a complicated crown fracture — a broken tooth where you can see a pink, red or dark spot in the middle of the break — the pulp is exposed. That means the nerve is open to the mouth.
It hurts. Then bacteria travel down the canal, kill the pulp, and infection reaches the bone at the root tip, where it forms an abscess. That process continues for months or years.
"We'll monitor it" is the most common and most harmful advice in this area. There is nothing to monitor. An exposed pulp does not recover. The only two treatments are root canal or extraction, and the only question is which.
Why your dog still eating means nothing
This is the single most important paragraph on this page.
Dogs and cats do not show dental pain the way we expect. They keep eating — because the alternative, in every instinct they have, is starving. They shift to the other side of the mouth, swallow food whole, or eat more slowly, and owners read continued eating as evidence of comfort.
The proof arrives after treatment. Owners routinely report that a dog they considered completely normal became more playful, more affectionate, and more willing to chew toys within a week or two of having a fractured tooth treated. That change is the pain leaving.
If your veterinarian has found a fractured tooth and your response is "but he's eating fine" — that is expected, and it is not reassurance.
Root canal or extraction?
Both are legitimate. Here is the honest comparison.
Root canal keeps the tooth. The infected pulp is removed, the canal cleaned, shaped, disinfected and filled, and the access sealed. The tooth stays in the jaw and stays functional.
This matters most for the canine teeth and the carnassial (upper fourth premolar). A canine tooth is a large structural component of the jaw — its root is longer than the visible crown and occupies a substantial portion of the bone. It matters functionally in working dogs, protection dogs, sporting dogs and any dog that carries things.
Root canal is also less invasive than it sounds: it is done through a small access hole, with no need to open the gum and remove bone.
Extraction is definitive. The problem is gone permanently and can never fail later. It is cheaper up front and available at far more practices.
But extracting a large canine tooth is not a small procedure. The gum is opened, bone is removed to expose the root, the tooth is sectioned and elevated out, and the gum is closed over the socket. Recovery is longer and more uncomfortable than a root canal on the same tooth. Owners who choose extraction on cost grounds are sometimes surprised by this.
Choose root canal when: the tooth is strategically important (canine, carnassial), the root and surrounding bone are healthy on radiographs, and the dog is a working or sporting animal.
Choose extraction when: there is significant periodontal disease or bone loss, the root is fractured, too little crown remains to restore, there is tooth resorption (very common in cats), or when cost is genuinely decisive.
Cats are different
Feline tooth resorption — where the tooth structure dissolves from within — is common in adult cats, painful, and makes endodontic treatment inappropriate. Root canals are performed in cats far less often than in dogs, mostly on fractured canines in otherwise healthy mouths. For most feline dental problems, extraction is the correct treatment.
Do you need a crown?
Not usually. A crown protects a treated tooth from re-fracturing and is worth considering for large dogs that chew hard, working and protection dogs, and any dog that broke the tooth on something it will encounter again.
It requires a second anaesthetic — one visit to prepare and impression the tooth, another to fit the crown — which is part of why it costs what it does. For most pet dogs it is optional.
While you are there: the things that break teeth are antlers, bones, hard nylon chews, ice cubes, and rocks. The rule of thumb from veterinary dentists is that if you cannot indent it with a thumbnail or would not want it dropped on your knee, it is too hard.
Success and follow-up
Root canal success rates in dogs are good — the large majority of treated teeth remain functional long term. Failures happen, usually because the canal system was complex or a root fracture was missed.
Your dentist will want a follow-up radiograph at six to twelve months to confirm the bone at the root tip has healed. This is not upselling; it is how success is confirmed, and it matters.
Who does it
Root canals need a board-certified veterinary dentist (DAVDC) or a general practitioner with substantial endodontic training and equipment. They are not a routine general-practice procedure. Dental radiographs before, during and after are non-negotiable — see our [dental X-rays guide](/procedures/dental-x-ray/).
Go now, not at the next check-up, if there is facial swelling below the eye, a draining tract on the face, or your pet has stopped eating.
Who isn't a candidate
- Other: A tooth with significant periodontal disease, root fracture, or too little remaining crown to restore — saving the root of a tooth whose support is gone achieves nothing, and extraction is the correct answer.
- Other: Extensive tooth resorption, which is common in cats and makes endodontic treatment inappropriate.
- Concurrent condition: Patients unfit for a long general anaesthetic — a root canal on a canine tooth takes considerably longer than an extraction.
- Other: A fractured deciduous (baby) tooth, which is extracted rather than treated.
Common questions
How much does a root canal cost for a dog?
Roughly $1,500 to $4,000 per tooth with a board-certified veterinary dentist, including anaesthesia, dental radiographs and the procedure itself. A crown adds $1,000 to $2,000 and requires a second anaesthetic. Extraction of the same tooth typically costs $800 to $2,000, though it is a more invasive operation than the price gap suggests.
Is a root canal better than extraction for a dog?
Neither is universally better. Root canal preserves a strategically important tooth — canines and carnassials are large structural parts of the jaw — and is less invasive than extracting the same tooth. Extraction is definitive, cheaper and more widely available. Extraction is the right answer where there is periodontal bone loss, a fractured root, too little crown left, or tooth resorption.
Is a broken tooth painful for a dog?
Yes, when the pulp is exposed — visible as a pink, red or dark spot in the middle of the fracture. Dogs and cats conceal dental pain and keep eating, which owners read as comfort. The evidence usually appears after treatment, when a dog considered completely normal becomes noticeably more playful and willing to chew within a week or two.
Do dogs need a crown after a root canal?
Not usually. A crown protects the treated tooth from re-fracturing and is worth considering for large dogs that chew hard, and for working, protection and sporting dogs. It costs $1,000 to $2,000 and needs a second anaesthetic for preparation and fitting. For most pet dogs it is optional rather than standard.
How do I know if my dog's broken tooth needs treatment?
Any fracture exposing the pulp — a pink, red or dark centre to the break — needs root canal or extraction, and monitoring is not a third option. Go urgently if there is facial swelling below the eye, a draining tract on the face, or your pet has stopped eating. Dental radiographs are needed to decide which treatment is appropriate.
