An impacted canine is a canine tooth that fails to come through into its normal position and stays buried in the gum and bone. The upper canines, the pointed teeth near the front of the smile, are the most commonly impacted teeth after the wisdom teeth, affecting an estimated 1 to 3 percent of people. Catching the problem early, often around age 9 to 12, gives the best chance of guiding the tooth into place rather than removing it.
Key takeaways
- An impacted canine is stuck below the gum instead of erupting normally.
- Upper canines are affected most, in roughly 1 to 3 percent of people.
- Early detection on an X-ray, around age 9 to 12, gives the most options.
- Most cases are treated by exposing the tooth and guiding it down with braces.
- Left unmanaged, an impacted canine can damage the roots of nearby teeth.
Why do canines become impacted?
Canines have the longest path to travel of any tooth, which is part of why they get stuck. Several factors can play a role.
Crowding and lack of space
If the dental arch is short or crowded, the canine may not have room to drop into line, so it stays high in the bone. This is one reason orthodontists watch the canines closely in children with crowding. Our guide to straightening crooked teeth explains how space problems develop.
Position and angle
Sometimes the tooth bud sits in the wrong place or tips at an angle, so it grows toward the roof of the mouth (palatal) or the cheek side (buccal) rather than straight down. In Western populations, palatal impaction is the more common pattern.
Extra or missing teeth
An extra tooth, or a missing or small adjacent tooth, can block or misdirect the canine. Our guide to extra teeth in children covers this in more detail.
How is an impacted canine found?
Often there are no symptoms, which is why routine checks matter. A dentist may suspect an impacted canine when a baby canine has not fallen out on time, when there is a gap where the adult canine should be, or when a small bulge is felt in the gum. An X-ray confirms the position, and in some cases a 3D scan is used to map exactly where the tooth sits before planning treatment. Only imaging can show whether the tooth can be guided into place. This is similar to how we assess early orthodontic problems in children, where the first check is recommended around age 7.
How impacted canines are treated
The right approach depends on the age of the patient, the position of the tooth, and how much space is available. The table below outlines the common pathways.
| Approach | When it is used | General notes |
|---|---|---|
| Monitor and create space | Caught early, tooth may still erupt | Braces or a plate open space so the tooth can drop in |
| Expose and guide (traction) | Tooth is impacted but savable | Minor surgery uncovers the tooth, braces gently pull it into line |
| Remove the canine | Tooth is badly positioned or fused | Followed by braces, a bridge or an implant to fill the space |
| Transplant or other options | Selected complex cases | Specialist decision, less common |
The most common treatment for a savable canine is exposure and traction. A small procedure uncovers the top of the buried tooth and attaches a tiny bracket and chain. Braces then apply gentle, steady force over several months to walk the tooth down into the arch. It is a slow process, but the result is your own natural canine in the right place, which is well worth the wait. Our what to expect with braces guide explains the orthodontic side.
What happens if it is left alone?
An untreated impacted canine is not always harmless. It can press on and damage the roots of neighbouring teeth, form a cyst around the buried crown, or leave a gap that affects the bite and smile. This is why early detection and a clear plan matter, even when there are no symptoms.
Frequently asked questions
At what age are impacted canines usually found?
Most are detected between about 9 and 12 years, when the adult canines are due to come through. This is why regular checks during these years are valuable.
Is treatment painful?
The exposure procedure is done with anaesthetic, and any soreness afterwards is usually mild and short lived. The orthodontic movement feels like the normal pressure of braces.
How long does it take to bring the tooth down?
It varies with the position of the tooth, but guiding an impacted canine into line often takes many months and is part of a longer course of braces.
Can adults have impacted canines treated?
Yes, though the longer a tooth has been impacted the more it can fuse to the bone, which lowers the chance of moving it. Early treatment is more predictable.
Will I need a tooth removed?
Not usually. The aim is to save the canine. Removal is reserved for teeth that are too poorly positioned or damaged to guide into place.
The takeaway
An impacted canine is a common and treatable problem, most often picked up in late childhood on a routine X-ray. In most cases the tooth can be exposed and gently guided into place with braces, preserving your natural smile. Early detection gives the most options, so regular checks during the canine eruption years are key. To arrange an assessment, contact the team at Lumi Dental or see our current deals page.
