Your teenager has been wearing braces for months. The crowded front teeth are beginning to straighten, the gaps are getting smaller, and every orthodontic appointment seems to bring another sign of progress. Except for one thing: a canine tooth still hasn't appeared.
Maybe the baby tooth is hanging on longer than expected. Maybe there's an empty space where an adult tooth should be. Either way, it's reasonable to wonder why the braces seem to be working everywhere except that one spot.
The missing tooth may not be missing at all. Sometimes a permanent canine develops beneath the gums but cannot follow its normal path into the mouth. Dentists call this an impacted canine.
For parents, the important question isn't simply how long the tooth will take to appear. It's whether that tooth has a clear path to come in, and what the orthodontist can do if it doesn't.
The Other Teeth Are Moving, but One Still Hasn't Appeared
Braces can straighten teeth that have already erupted, but a tooth buried beneath the gums presents a different challenge. Before an orthodontist can guide it into position, they need to know where it is and what's preventing it from emerging.
When Permanent Canine Teeth Usually Come In
The upper permanent canines, sometimes called eye teeth, typically erupt between ages 11 and 13. They sit between the lateral incisors and the premolars, with roots that help make them important teeth for biting and guiding jaw movement.
Not every child follows the same eruption schedule. A tooth appearing somewhat later than expected isn't automatically a sign of trouble, particularly when other permanent teeth are still developing.
However, an upper canine that remains unerupted while surrounding teeth have come in deserves closer evaluation. This is especially true when the matching canine on the opposite side erupted much earlier, or a baby canine remains in place.
The orthodontist will consider your teen's age, dental development, existing X-rays, and how much room is available before deciding whether the delay is concerning.
Why a Tooth Can Remain Trapped Beneath the Gums
A permanent canine may have enough room to fit between neighboring teeth but still be pointed in the wrong direction. Some impacted canines develop toward the roof of the mouth. Others sit closer to the lips or remain unusually high in the jawbone. Their position may prevent them from emerging without assistance.
Crowding can contribute, but it isn't the only explanation. An unusual eruption angle, a retained baby tooth, an extra tooth, or other obstruction may interfere with the normal eruption path.
Family history can also play a role. The American Association of Orthodontists identifies several possible contributors to tooth impaction, including inadequate space, abnormal eruption direction, and genetic factors.
This is why simply making more room with braces doesn't always solve the problem. The tooth may have space available but still be unable to travel into it.
What the Orthodontist Looks for Before Recommending Treatment
When a canine hasn't erupted, the next step isn't automatically surgery. The orthodontist first needs to establish the tooth's location, orientation, and relationship to the surrounding teeth.
These findings help distinguish a tooth that may erupt with monitoring from one needing early intervention or surgery. The important questions are whether its position is improving and whether it threatens a neighboring root, not merely whether the braces have made enough space.
How Imaging Helps Locate an Impacted Canine
An orthodontist may begin with a clinical examination and dental X-rays, often including a panoramic image that shows developing teeth across both jaws. The images can reveal whether the canine is angled toward a neighboring tooth, positioned unusually high, or blocked by another structure.
Sometimes conventional X-rays don't provide enough information about its exact location. In selected cases, the orthodontist may recommend cone-beam computed tomography, or CBCT, to create a three-dimensional view.
The American Academy of Pediatric Dentistry advises choosing dental imaging according to a child's examination and treatment needs. CBCT is not routine for impacted canines; its added detail should justify the radiation exposure and be likely to affect treatment planning.
Parents can ask the orthodontist to point out the canine's crown and the adjacent roots on the image, explain what each image adds, and identify which finding would change the treatment plan.
Why the Tooth's Position Matters for Nearby Teeth
A canine doesn't develop in isolation. Its crown may lie near the roots of the front teeth, and an unfavorable position can sometimes cause damage that isn't visible during a routine examination.
One concern is root resorption, in which part of a neighboring tooth's root structure is lost. An impacted canine may also interfere with orthodontic movement or contribute to crowding.
These complications don't occur in every case, and an unerupted canine doesn't necessarily mean neighboring teeth are being harmed. For example, two teenagers may have the same visible gap, but one canine points toward it while the other's crown overlaps an incisor root on an X-ray. Their treatment choices may be different even though their smiles look similar.
However, this possibility helps explain why an orthodontist may recommend further investigation even when the teenager has no pain.
A tooth can remain buried beneath the gums without causing obvious symptoms. Waiting for discomfort before seeking an evaluation isn't a reliable way to determine whether it needs attention.
When Braces Alone Cannot Bring the Tooth Into Place
Parents sometimes assume that a stronger orthodontic wire or a few extra appointments will make the canine appear. But the choice is not simply between pulling harder and scheduling surgery. But braces cannot reliably move a tooth into position when its location prevents the orthodontist from attaching an appliance or applying the appropriate force.
Monitoring may be reasonable when the canine has a favorable position, enough space, and no sign that nearby roots are at risk. It should include a planned reassessment rather than indefinite waiting. In younger patients, a clinical review available through the National Library of Medicine explains that removing a retained baby canine may help a displaced upper permanent canine erupt, although success depends on the child's age, available space, and tooth position.
The choice depends on age, root development, and the canine's angle and position on X-rays. Extraction can improve the chance of eruption, but it is not a guarantee. Surgical exposure with orthodontic traction is another option when the permanent tooth cannot reach the space predictably, or its position creates a concern for adjacent teeth.
The orthodontist and oral and maxillofacial surgeon decide whether this approach is feasible. Parents can ask what evidence favors the chosen option and what would trigger a change of course.
How an Oral Surgeon May Help Expose an Impacted Tooth
When examination and imaging suggest the canine is unlikely to emerge with space-making, early extraction of the baby tooth, or observation alone, the team may consider surgical exposure.
The goal is generally to uncover enough of the tooth for orthodontic treatment to continue, rather than remove the permanent canine.
The surgeon carefully opens or repositions the gum covering the tooth. Depending on its location, a small amount of surrounding bone may also need to be removed. A bracket or another orthodontic attachment may then be bonded to the exposed crown.
The American Association of Oral and Maxillofacial Surgeons explains that a bracket and chain can connect the exposed tooth to orthodontic appliances for gradual movement. The approach also depends on whether the canine lies toward the palate or the outer side of the arch.
The surgeon carefully uncovers enough of the impacted canine for an orthodontic attachment to be placed. Oral surgery resources also explain this exposure-and-bonding process visit website to know more, although the specific approach depends on the tooth's position and surrounding tissues. The orthodontist then uses the attachment to gradually guide the canine into place.
Importantly, surgery doesn't immediately put the canine into its final position. It creates an opportunity for the orthodontist to begin moving the tooth gradually.
How Surgical Exposure and Orthodontic Traction Work Together
In some procedures, the surgeon attaches a small chain to the bracket bonded onto the impacted canine. The orthodontist can later use this attachment to apply gentle, controlled traction through the braces, gradually encouraging the canine toward the available space.
The movement must be carefully managed. The orthodontist needs to consider not only where the canine should end up but also how to move it without unnecessarily affecting nearby teeth or their roots.
Traction often takes months, and a deeply displaced canine may take longer. The starting angle, root development, and response to controlled force affect the timeline. Rather than promising an eruption date, the team can explain what movement it expects to see at future checks.
A canine that moves slowly is not necessarily failing treatment. If repeated evaluations show little or no movement, the team may investigate factors such as ankylosis, when the tooth is fused to surrounding bone and cannot respond normally to traction.
If traction is unlikely to succeed, the clinicians may consider continued monitoring, removal of the impacted tooth, or another plan for managing the space. The appropriate fallback depends on tooth health, position, and the available bite and restorative options.
Those options must be weighed against possible damage to neighboring roots, the chances of successful movement, and the effects on the bite.
What Parents Should Know Before the Procedure
Hearing that their teenager might need oral surgery can make parents anxious, especially when the child has already spent considerable time in braces.
Discussing the procedure, anesthesia plan, and likely recovery can help families prepare and make informed decisions.
Understanding Anesthesia and Recovery Instructions
Surgical exposure may be performed using local anesthesia, sometimes with sedation, or under general anesthesia, depending on the procedure, patient needs, and clinical setting. The surgeon should explain which approach is appropriate, what the teenager may experience, and what preparation is required.
Parents should give the team a complete medical history, including medications, allergies, previous anesthesia problems, and conditions that may affect breathing. Joint guidance from the American Academy of Pediatrics and American Academy of Pediatric Dentistry calls for careful pre-sedation assessment and appropriate monitoring.
If sedation or general anesthesia is planned, the family should receive individualized instructions on fasting, transportation, recovery supervision, and when the teen can safely leave the facility. Families should follow the clinical team's instructions rather than a generic fasting rule.
After the procedure, temporary soreness, swelling, and minor bleeding may occur. Families may receive instructions about pain relief, food choices, mouth cleaning, and caring for stitches or an orthodontic attachment.
The British Association of Oral and Maxillofacial Surgeons provides patient guidance on impacted canine exposure, including the different ways a tooth may be uncovered and prepared for orthodontic treatment.
Parents should follow their own surgical team's instructions rather than applying general advice from unrelated dental procedures.
Planning Around School and Family Activities
For teenagers, the biggest concern may be less about the procedure itself and more about how it affects their routine. School attendance, sports practice, meals, and social plans can all become part of the discussion.
Some teenagers can return to ordinary activities relatively soon, while others need more recovery time depending on the surgery and anesthesia used. Families should ask the surgeon when school, exercise, and contact sports can safely resume.
Preparing a few soft meals can make the initial recovery period easier. It also helps to check which foods might disturb a bracket, chain, or protective dressing.
If an attachment loosens or a dressing becomes displaced, the family should contact the treating team rather than attempting to repair it at home.
Worsening pain, fever, increasing swelling, persistent bleeding, or other unexpected symptoms also warrant prompt professional advice. Severe bleeding or difficulty breathing requires emergency medical attention.
Keeping written recovery instructions accessible helps everyone know whom to call if symptoms or an attachment cause concern.
Why Treatment Continues After the Tooth Is Exposed
Healing of the gum is only one part of treatment; the canine may still be far from its final position. Unlike an erupted tooth, a buried canine must travel through a planned path before its alignment and bite can be assessed.
How Orthodontists Guide the Tooth Into Position
Once initial healing permits, the orthodontist can begin or continue applying controlled force to the impacted canine. At regular visits, the orthodontist can check the tooth's direction of movement and adjust forces while protecting neighboring roots.
Sometimes space must be maintained while the canine moves into place. The orthodontist may also need to modify the direction of traction as the tooth changes position.
Applying more force does not necessarily speed this process and can increase the risk of damage to neighboring teeth or their supporting tissues.
The teenager may eventually see part of the canine emerge through the gum. That is an encouraging development, but it doesn't mean treatment is finished.
The tooth still needs to reach an appropriate position within the dental arch, and the orthodontist must evaluate its alignment, bite relationships, and surrounding tissues.
Why Follow-Up Appointments Matter
Follow-up visits are used to assess progress and identify problems before they worsen. The orthodontist checks the canine's movement, attachment stability, gum health, and signs of damage affecting neighboring teeth.
If a surgical site needs additional assessment, the oral surgeon may also be involved. Possible setbacks include a loose attachment, gum irritation, damage to an adjacent root, or a tooth that remains stationary despite traction.
If movement stalls, the team may compare current and earlier images, reassess the tooth's position, and determine whether continuing traction remains appropriate.
Parents can help by keeping appointments, reporting unexpected symptoms, and ensuring their teenager follows the prescribed cleaning and appliance-care instructions.
Parents can report changes between visits, but adjustments to traction should always be made by the treating clinicians.
Helping Your Teen Stay Patient Through a Longer Treatment Plan
By the time an impacted canine becomes the main focus of treatment, your teenager may already be tired of braces. They've sat through adjustments, dealt with food restrictions, and watched friends finish orthodontic treatment sooner.
Being told that another procedure or several more months of treatment may be needed can feel discouraging. Acknowledging that frustration is more helpful than telling them the extra treatment shouldn't matter.
Parents can also make the process easier by explaining what the orthodontist is trying to accomplish. The goal isn't simply to make one more tooth visible. It's to determine whether the permanent canine can be brought into a functional position while protecting the rest of the teeth.
You can help your teen take a more active role by encouraging them to ask questions at appointments:
Where is the impacted canine now, and has its position changed?
Is there enough room for it to erupt safely?
What are the benefits and risks of the recommended approach?
How will we know whether the treatment is working?
What happens if the tooth doesn't respond as expected?
Early orthodontic checks also aim to identify eruption problems before they become more complicated.
The American Association of Orthodontists recommends that children have an initial orthodontic evaluation by age seven, allowing developing eruption and alignment concerns to be identified early. That doesn't mean every child needs braces at that age, but it illustrates the value of checking how permanent teeth are developing before problems become more complicated.
For a teen already wearing braces, however, the focus is the tooth's present position and the options available now. A delayed canine does not, by itself, mean the braces have failed.
It may require a separate plan while the other teeth continue responding to treatment. With imaging, careful planning, and coordination when needed, many impacted canines can be guided into place; others require alternative treatment.
For parents, the useful next step is to ask what is keeping the tooth from erupting, whether it threatens a neighboring root, why the recommended treatment is preferable to the alternatives, and what finding would prompt the team to reconsider its plan.
Even when the plan takes longer than expected, knowing the purpose of each step can help your teenager stay engaged.
