What This Guide Covers and Who It Is For
This guide explains impacted canine surgery for patients, parents, and anyone facing this common dental condition. It covers how the procedure works, what recovery looks like, and what it typically costs.
Canine teeth, sometimes called "eye teeth," sit in the corners of your upper and lower arches. They are the pointed teeth that help you tear food and also play a key role in guiding your bite. When a canine fails to erupt through the gum on its own, it is called an impacted canine. [1]
Impacted canines are the second most commonly impacted teeth after wisdom teeth. Unlike wisdom teeth, which are often simply removed, canines are critical for function and appearance. The goal of treatment is almost always to save the tooth and guide it into its correct position. [1] [3]
Most impacted canine cases involve a team approach. An oral surgeon performs the surgical exposure, and an orthodontist handles the braces or aligners that move the tooth into the arch over time.
Understanding Impacted Canines
An impacted canine is a permanent canine tooth that is stuck beneath the gum, bone, or both and cannot erupt into the mouth on its own.
Why Canines Become Impacted
Upper canines have one of the longest and most complicated paths of any tooth as they develop and move toward the gum line. They begin forming high in the jaw, near the eye socket, and must travel downward and forward to reach their final position. Several factors can block this path.
Crowding is one of the most common reasons. When there is not enough space in the arch, the canine may become blocked by neighboring teeth. Other causes include extra teeth (called supernumerary teeth), cysts, or an unusual growth angle of the tooth itself. [3]
Genetics also play a role. If a parent had an impacted canine, their children are more likely to experience the same condition. A review published in the <em>European Journal of Orthodontics</em> confirmed a strong hereditary component to palatal canine displacement. [3] Upper canines are impacted far more often than lower canines, and the condition is roughly twice as common in females. [3]
Palatal vs. Buccal Impaction
The position of the impacted canine determines which surgical technique is used. There are two main categories based on where the tooth is trapped.
A palatally impacted canine sits on the roof-of-the-mouth side of the arch. This is the more common type for upper canines. A buccally impacted canine sits on the cheek side, closer to the outer surface of the gum. Your oral surgeon will use X-rays or a cone-beam CT scan (a 3D X-ray of the jaw) to determine the exact location and plan the surgical approach. [1]
Palatal impactions are often treated with an open exposure technique, where the surgeon uncovers the tooth and places a bracket on the same day. Buccal impactions may be treated with a closed eruption technique, where the surgeon uncovers the tooth, bonds a bracket with a small chain, and then closes the gum tissue back over it. The orthodontist later uses the chain to apply gentle pulling force. Both the open and closed eruption techniques have high success rates. A major multicenter randomized controlled trial found no significant difference in long-term periodontal (gum) health between the two methods, so the best choice often depends on the tooth's specific position, the amount of attached gingiva present, and the surgeon's clinical judgment. [5]
What Happens If an Impacted Canine Is Not Treated
Leaving an impacted canine untreated can lead to several problems over time. The impacted tooth may develop a dentigerous cyst (a fluid-filled sac) around its crown, which can damage surrounding bone and nearby tooth roots. [3] [4]
The impacted canine can also resorb (dissolve) the roots of adjacent teeth, particularly the lateral incisors. The reported prevalence of root resorption of neighboring incisors varies widely across studies, ranging from 12% to over 60% depending on the study population and the imaging method used. [3] This means the risk can be substantial, and affected teeth may become loose or require extraction. Additionally, the baby canine that remains in place as a placeholder will eventually loosen and fall out, leaving a gap.
In many cases, the longer treatment is delayed, the more difficult it becomes. Older patients tend to have denser bone, which can make tooth movement slower. This is one reason early detection is so valuable. [4]
Timing, Detection, and Preparation
Early detection around age 10 to 12 gives your child the best chance for a simpler and shorter treatment. [4]
When to Screen for Impacted Canines
The American Association of Orthodontists recommends that every child receive an orthodontic evaluation by age 7, which helps catch developmental issues early. [4] A panoramic X-ray (a single image that shows all the teeth and jaws) taken around age 10 to 12 can reveal whether the permanent canines are developing along a normal path.
At this age, a dentist or orthodontist can spot warning signs such as the canine drifting toward the midline, lack of a normal bulge above the gum where the canine should be, or a baby canine that is unusually firm and shows no signs of loosening. If any of these signs are present, further imaging is typically recommended. [4]
Early intervention sometimes involves removing the baby canine to clear a path for the permanent one. Research published in the <em>American Journal of Orthodontics and Dentofacial Orthopedics</em> found that extracting the primary canine in children aged 10 to 13 with palatally displaced canines led to spontaneous improvement in the eruption path in a substantial percentage of cases, though results vary depending on the degree of displacement. [4] In some cases, this simple step allows the impacted tooth to self-correct and erupt on its own without surgery.
How to Prepare for the Procedure
Before surgery, the oral surgeon will review imaging and coordinate a plan with the orthodontist. In most cases, braces or another orthodontic appliance are placed first to create space in the arch for the canine. This step may take several months before the surgical appointment. [1]
Your surgeon will provide specific pre-operative instructions. If sedation or general anesthesia will be used, you will typically need to avoid food and drink for a set number of hours before the procedure. Arrange for someone to drive you or your child home afterward.
Stock your kitchen with soft foods such as yogurt, mashed potatoes, smoothies, and soup. Have ice packs ready. Fill any prescribed medications in advance so they are available immediately after surgery.
What Happens During and After Surgery
The procedure typically takes 30 to 60 minutes per tooth and is performed in the oral surgeon's office.
During the Surgical Exposure
The surgery is performed under local anesthesia (numbing injections near the tooth). Many patients, especially younger ones, also receive IV sedation or nitrous oxide (laughing gas) for comfort. General anesthesia is an option for complex cases or anxious patients. [1]
The oral surgeon makes an incision in the gum tissue to expose the crown of the impacted canine. If bone is covering the tooth, a small amount is carefully removed. Once the tooth surface is visible, the surgeon cleans and dries it.
A small orthodontic bracket is bonded directly to the exposed tooth using dental adhesive. A thin gold chain or wire is attached to the bracket. Depending on the technique, the surgeon may leave the tooth uncovered (open technique) or stitch the gum tissue back over the tooth with only the chain visible (closed technique). [1] [5]
The chain is then loosely tied to the orthodontic archwire. Over the following weeks, the orthodontist will begin applying gentle traction to slowly guide the canine into the arch.
Recovery Timeline
Most patients return to normal activities within 3 to 5 days. The first 48 hours are typically the most uncomfortable. Swelling usually peaks on the second or third day and then gradually subsides.
Pain is commonly managed with over-the-counter medications such as ibuprofen or acetaminophen. Your surgeon may prescribe a stronger pain reliever for the first day or two. An ice pack applied to the cheek in 20-minute intervals helps reduce swelling during the first 24 hours.
Stick to soft, cool foods for the first few days. Avoid hot liquids, straws, and vigorous rinsing for the first 24 hours, as these can disturb the surgical site. After the first day, gentle warm salt water rinses (half a teaspoon of salt in a cup of warm water) can help keep the area clean.
Stitches, if used, are typically dissolvable and fall out on their own within one to two weeks. A follow-up appointment with the surgeon is usually scheduled within 7 to 14 days to check healing.
The Orthodontic Phase After Surgery
After the surgical site heals, the orthodontist begins activating the chain or elastic attached to the bracket. This usually starts two to four weeks after surgery. The orthodontist adjusts the force at regular appointments, typically every four to six weeks.
Complete alignment of the canine into the arch may take 6 to 18 months, depending on the tooth's starting position, the patient's age, and how the bone and tissue respond. Younger patients often see faster movement because their bone is less dense. [3]
Throughout this phase, patients continue wearing braces as normal. The erupting canine will gradually become visible in the gum line and eventually settle into its correct position. Once the tooth is aligned, the overall orthodontic treatment continues until all teeth are properly positioned.
Success rates for combined surgical exposure and orthodontic treatment are generally high. A retrospective study of 56 impacted maxillary canines by Becker and Chaushu found that younger patients (treated before age 30) had significantly better outcomes than older patients, and that teeth in favorable positions were aligned successfully in the large majority of cases. [6] A separate study by Zuccati and colleagues, which followed 215 palatally impacted canines, reported a success rate of about 94% when treatment began at a younger age. [7] Outcomes can be less predictable in older adults or when the canine is severely displaced.
Cost of Impacted Canine Surgery
Surgical exposure of an impacted canine typically costs between $800 and $2,500 per tooth. Costs vary by location, provider, and case complexity.
This range covers the surgical fee only. It does not include the cost of orthodontic treatment, which is a separate and often larger expense. Full orthodontic treatment with braces may range from $3,000 to $7,000 or more, depending on the length of treatment and the type of appliance used. Costs vary by location, provider, and case complexity.
Several factors influence the surgical cost. These include the position and depth of the impacted tooth, the type of anesthesia used, whether the procedure is performed in an office or hospital setting, and whether one or both canines are impacted.
Many dental insurance plans cover a portion of impacted canine surgery because it is considered a medically necessary procedure rather than a cosmetic one. Contact your insurance provider before treatment to confirm your coverage. Ask the oral surgeon's office for a pre-authorization or predetermination of benefits so you know your expected out-of-pocket cost before the procedure.
When to See a Specialist
A specialist referral is appropriate any time a canine tooth fails to erupt on schedule or imaging reveals an abnormal position.
Your general dentist or pediatric dentist is typically the first to identify a potential impaction during routine X-rays. If a permanent canine has not begun to erupt by age 13 or 14, or if the baby canine is still firmly in place without signs of loosening by age 12, your dentist will likely refer you to an orthodontist for evaluation. [4]
The orthodontist assesses the position of the impacted canine and determines whether surgical exposure is needed. If surgery is recommended, the orthodontist coordinates with an oral surgeon who specializes in these procedures. [1]
There are a few situations where a canine may not be salvageable. If the tooth is severely ankylosed (fused to the bone), positioned too close to adjacent roots to move safely, or if the patient is an older adult with very dense bone, extraction may be considered. In these cases, the space can be closed orthodontically or restored with a dental implant. Your specialist team will discuss all options and help you make an informed decision.
