Impacted Canine: What Parents Should Know Before the Scan
An impacted canine is an eye tooth, usually in the upper jaw, that is stuck in the bone and has not come into the mouth at the expected age. It is common, it is treatable, and most children do well. A 3D scan is sometimes needed to see exactly where the tooth lies, and it is requested only when that position changes the plan.
Hearing that a tooth is "impacted" can sound alarming. This guide explains what it means, how it is found, what the scan is for, and what treatment usually involves, in plain language.
What Is an Impacted Canine?
The canines are the pointed teeth at the corners of the smile. The upper ones are among the last teeth to come in, usually between 11 and 13 years of age. A canine is called impacted when it is blocked from coming through, often because of crowding, a tooth that came in out of position or a slightly off path of eruption.
How It Is Noticed
A baby canine that is still in place well after the usual age.
A visible bump on the gum above the baby canine that is missing on the other side.
The permanent canine on one side coming through while the other has not.
Neighbouring teeth that look crowded or tilted.
Often, nothing at all, and an X-ray at a routine visit is how it is found.
Dentists often check for it from around age 10 to 11, because finding it early gives more options.
Why It Matters
A canine that stays buried can push on the roots of the tooth beside it and, in some cases, damage them. It can also leave a gap in the smile and affect the bite. The canine is a strong tooth that matters for chewing and for the shape of the smile, so the aim is usually to bring it into line and not to remove it.
The Scan: Why a 3D Image May Be Suggested
A routine X-ray shows that a canine is buried but not always exactly where and how. A 3D scan, called a CBCT, shows the tooth from every angle, how close it sits to the roots of its neighbours and whether anything is in its way. That helps the Orthodontist and surgeon choose the route and method of treatment.
It is not automatic. Ask: "What will the scan show that the ordinary X-rays cannot, and how will it change the plan?" A clear answer means the scan is justified. The orthodontic guide to CBCT covers the clinical criteria for Orthodontists, and balancing diagnostic need and radiation in children explains how doses are kept low for young patients.
What happens on the day
The child stands or sits still for under a minute while the scanner moves around the head. It is painless. Metal such as earrings and hair clips should be removed first and how to prepare for a CBCT scan has a checklist.
Treatment Options
Watchful waiting. Sometimes a baby canine is removed in a young child, which gives the permanent canine room to correct its own path.
Braces and a small procedure. The Orthodontist makes space, then a surgeon exposes the buried tooth and attaches a small bracket so it can be gently guided into place over several months.
Removal and replacement. Rarely, if the tooth is badly positioned or is harming neighbouring roots, it may be removed and replaced with a bridge or an implant later.
Treatment often takes a year or more in total, because the tooth is moved slowly. The plan depends on the child's age, the tooth's position and the Orthodontist's assessment.
Supporting Your Child Through Treatment
Treatment for an impacted canine is long, and children cope best when they know what is happening. Explain each step in simple terms, keep appointments for adjustments, and reinforce careful cleaning around the braces and the bracket on the exposed tooth. Mild soreness after the small procedure is usual and settles in a few days. Report swelling that increases, a bracket that comes loose or persistent pain to the Orthodontist promptly.
Questions Worth Asking
How far is the tooth from the roots of its neighbours?
Is early removal of the baby canine advisable?
Which treatment do you recommend, and what is the alternative?
How long is treatment likely to take?
Is a 3D scan needed, or will ordinary X-rays do?
Frequently Asked Questions
-
Dentists usually look from about 10 to 11 years, earlier if a baby canine is loose or a bump is visible.
-
Usually not. Most are found on routine X-rays without symptoms.
-
Sometimes, especially if found early and space is made, but it needs monitoring.
-
No. It is used when its position affects how treatment is planned.
-
The dose is low and the field is kept small, but it should be used only when it changes the plan.
