Crown Height Reduction

Crown height reduction and vital pulpotomy is a common procedure for young dogs with malpositioned teeth, particularly those with Class 2 Malocclusion (overbite), where the mandibular canines traumatise the roof of the mouth, or Class 1 Malocclusion (linguoverted mandibular canines). Orthodontic movement may not be feasible for these patients, and leaving the condition untreated can lead to chronic pain and oronasal fistula formation.

About the Crown Height Reduction procedure

The procedure starts with reducing the height of the mandibular canines and exposing the sensitive pulp inside the tooth. Because this delicate pulp is vulnerable to external elements, we cover it to ensure proper protection.

We carefully drill into the tooth to amputate a small portion of the pulp, creating space for a filling. Next, we apply a layered filling, with the first layer directly contacting the pulp tissue. This layer acts as a physical barrier against bacterial penetration and stimulates the formation of new dental material beneath it, promoting the tooth’s long-term health and stability.

“Teeth treated with vital pulpotomy generally do well, with a 90% success rate when performed correctly.”

Long-term success & monitoring

Teeth treated with vital pulpotomy generally do well, with a 90% success rate when performed correctly. To ensure the treated tooth remains healthy and continues to mature, we must periodically examine it throughout the patient’s lifetime. The first check occurs three months after the procedure, where we assess the integrity of the filling and look for any signs of pathology through dental radiographs.

We expect to see continued maturation of the tooth. If not, or if signs of infection are present, further treatment, such as root canal therapy or extraction, may be necessary. This procedure helps retain jaw structure and maintain function, offering an advantage over tooth extraction.

Post-Procedure Care & Treatment Evaluation

After a crown height reduction and vital pulpotomy, patients should avoid playing with abrasive toys like tennis balls.

It’s also important to be mindful of play behaviour and avoid throwing hard objects for catching to minimise the risk of damaging the fillings.

There is no need to change diet or chewing behaviours.

This treatment can be an excellent choice for the right patient. We can determine if it suits your pet through a thorough assessment and a discussion of all available treatment options.

Diplomate, American Veterinary Dental College™

Hi, I’m Dr Bec Tucker, and my journey into veterinary dentistry has been unexpected yet incredibly fulfilling. In fact, dentistry wasn’t on my radar at all when I graduated with a BVSc (Hons) from the University of Sydney in 2007. I was fortunate to meet veterinarians who had found their passion for dentistry, and their encouragement and enthusiasm shifted my perspective. Through continuing education lectures and workshops, I went from not fancying dentistry and oral surgery to genuinely loving it.

FAQs

What is crown height reduction and when is it recommended?

Crown height reduction is a procedure that shortens the lower canine teeth and protects the exposed pulp with a vital pulpotomy to stop palate trauma from malocclusions like overbite (Class 2) or linguoverted/base‑narrow canines (Class 1)—see the overview on Crown Height Reduction and the background on Malocclusion

Will my dog be under anaesthesia—and is it safe?

Yes; this is performed under general anaesthesia with specialist monitoring, and most patients go home the same day—see Complex Anaesthesia and the owner guide What to Expect

What outcomes can I expect and how successful is it long‑term?

When performed correctly, teeth treated with vital pulpotomy have about a 90% success rate, but they do require lifetime monitoring with the first recheck (exam + dental X‑rays) at 3 months—see Crown Height Reduction and Vital Pulpotomy

What does recovery look like—what can my dog chew after?

After treatment, avoid tennis balls and hard throw toys that could damage the filling, but there’s no need to change diet or normal chewing behaviours—see the after‑care on Crown Height Reduction

Could my dog still need a root canal or extraction later on?

If the pulp doesn’t survive despite best care, your specialist may recommend Root Canal Therapy or—less commonly—Extraction ; the pulpotomy page explains that failures can occur and why careful follow‑up imaging matters—see Vital Pulpotomy

What are the alternatives if height reduction isn’t the best fit?

Depending on age and suitability, interceptive orthodontics such as an Inclined Plane / Crown Extensions can tip canines into a safe position, while definitive options include Mandibular Canine Extraction. If the bite is causing palate injury, leaving it untreated risks issues like oronasal fistula, so an assessment is wise.

Key Takeaways

Purpose

CHR with vital pulpotomy stops palate trauma from overbite (Class 2) or linguoverted/base‑narrow canines (Class 1) when orthodontic movement isn’t feasible.

How it works

The canine crown is shortened, a small portion of pulp is removed, and a layered filling seals and protects the tooth to promote long‑term health

Outcomes & follow‑up

When performed correctly, success is ~90%. Patients need lifetime monitoring, with the first recheck at ~3 months, including dental X‑rays.

If progress stalls

Lack of maturation or signs of infection may require root canal therapy or extraction. CHR helps preserve jaw structure and function versus extraction.
