What Are Impacted Canines and How Are They Treated?
The journey to achieving a perfect smile involves a complex and highly coordinated process of dental development. Most people are familiar with the routine timeline of baby teeth falling out and permanent teeth taking their place. However, this biological transition is not always flawless. One of the most common and structurally significant complications that can occur during this developmental phase is the phenomenon of impacted canines. When a tooth is described as impacted, it means that it has been blocked from breaking through the gum line and assuming its natural position in the dental arch. While any tooth can become impacted, the third molars, commonly known as wisdom teeth, are the most frequent culprits. Following closely behind them are the maxillary canines, which are the upper eyeteeth. Unlike wisdom teeth, which are typically extracted because they serve no essential function in modern human chewing mechanics, the maxillary canines are absolutely vital for both the aesthetic harmony of the face and the functional mechanics of the human bite. Addressing an impacted canine is not just a matter of cosmetic improvement; it is a critical orthodontic necessity to prevent long term structural damage to the surrounding teeth and the jawbone. When patients or parents begin researching what impacted canines are and how they are treated, they are taking the first crucial step toward safeguarding a lifetime of oral health.
The Essential Role of Maxillary Canines in Your Smile
To truly understand why treating an impacted canine is so important, it is necessary to first understand the unique role these specific teeth play in the human mouth. The maxillary canines are often referred to as the cornerstones of the dental arch. They are situated at the critical transition point where the anterior teeth, the incisors, curve into the posterior teeth, the premolars and molars. Anatomically, canines are incredibly robust. They boast the longest and most deeply embedded roots of any human teeth, reaching far up into the maxillary bone just below the nasal cavity. This massive root structure is no accident of nature; it is designed to withstand the immense forces generated during the tearing and shearing of food.
Beyond their dietary function, the upper canines play a pivotal role in a functional concept known as canine guidance. When you slide your lower jaw from side to side, the shape and position of the upper and lower canines force the back teeth to separate slightly. This separation protects the highly complex and heavily ridged premolars and molars from grinding against each other during lateral movements, thereby preventing premature wear, enamel fracture, and unnecessary strain on the temporomandibular joint. If a canine fails to erupt properly, this delicate protective mechanism is lost, and the entire bite is compromised. Furthermore, the prominence of the canine roots provides essential structural support for the upper lip and the nasolabial folds. Without the presence of these teeth, the corners of the mouth can appear sunken or prematurely aged, demonstrating that their impact goes far beyond just chewing.
What Causes Canines to Become Impacted?
The eruption pathway of a maxillary canine is the longest and most complex of any tooth in the human mouth. They begin their development high up in the upper jaw, situated just below the eye socket, which is why they are colloquially termed eyeteeth. From this high vantage point, they must slowly migrate downward, navigating through the bone and navigating around the roots of adjacent teeth until they finally emerge into the oral cavity around the age of eleven or twelve. Because this journey is so lengthy and complex, there are numerous variables that can disrupt their path and lead to impaction.
One of the primary causes of impacted canines is a severe lack of space in the dental arch, a condition commonly known as dental crowding. If a patient has a naturally narrow upper palate or if their permanent teeth are disproportionately large compared to the size of their jaw, the canine may simply find no physical room to emerge. The teeth that erupt earlier, such as the central and lateral incisors, may drift into the space that was biologically reserved for the canine. Another significant factor is the prolonged retention of the primary canine, or the baby eyetooth. If the root of the baby tooth does not dissolve and resorb as it naturally should, it acts as a physical barrier, forcing the permanent canine to deflect off its intended path. Sometimes, the canine gets diverted toward the roof of the mouth, resulting in a palatal impaction, or it gets diverted toward the cheek, resulting in a buccal impaction.
Genetics also play an undeniable role in this condition. If a parent or sibling experienced impacted teeth, there is a statistically higher probability that the younger members of the family may face similar orthodontic challenges. Additionally, the presence of extra teeth, known as supernumerary teeth, or the development of unusual cellular growths like cysts along the eruption pathway can physically block the canine from descending. In some instances, the lateral incisors, which sit right next to the canines, develop with abnormally small or peg-shaped roots. Because the erupting canine relies on the root of the adjacent lateral incisor as a structural guide to slide down into place, an undersized or missing lateral incisor can leave the canine completely lost in the bone, ultimately leading to impaction.
Recognizing the Symptoms of an Impacted Canine Tooth
Because impacted canines are buried beneath the gum tissue and bone, they are not always immediately obvious to the naked eye. In many instances, the patient feels absolutely no pain, and the condition is only discovered during a routine dental examination. However, there are several visual and physical indicators that parents and adult patients can watch out for. The most glaring symptom is simply the delayed eruption of the tooth. By the time a child reaches their thirteenth birthday, the permanent upper canines should ideally be visible. If the baby canine is still firmly in place well into the teenage years, or if the baby tooth has fallen out but the space has remained entirely empty for several months, it is a strong indication that the permanent tooth may be stuck in the bone.
Another potential symptom is the shifting or flaring of the adjacent teeth. As an impacted canine tries to force its way down, it can push against the roots of the nearby lateral incisors or premolars, causing those visible teeth to tip, twist, or become unusually loose. In cases of palatal impaction, where the tooth is stuck pointing toward the roof of the mouth, a patient might actually be able to feel a hard, painless bump or swelling on the palate right behind their front teeth. Conversely, if the tooth is impacted toward the front of the jaw, a similar hard protrusion might be felt high up in the gums above the other teeth. While pain is not universally present, some patients do experience a dull, throbbing ache, sinus pressure, or tender gums in the region where the tooth is trapped, particularly if a cyst has begun to form around the crown of the impacted tooth.
The Diagnostic Process for Impacted Teeth
The absolute most critical factor in successfully treating an impacted canine is early detection. The American Association of Orthodontists highly recommends that all children undergo their first comprehensive orthodontic evaluation by the age of seven. While this may seem incredibly young, as most children still have a mouth full of baby teeth at this age, it allows the orthodontic team to evaluate the underlying skeletal structure and monitor the development of the adult teeth that are still forming inside the jaw. At Esteem Braces & Aligners – North Miami Beach, the focus on early intervention is a primary aspect of ensuring that minor developmental delays do not escalate into severe surgical interventions later in life.
During a diagnostic evaluation, the doctor will visually inspect the dental arch and physically palpate the gums to check for the presence of the developing canines. The true diagnostic power, however, lies in advanced radiographic imaging. A standard panoramic x-ray is generally the first tool used. This two-dimensional image provides a broad overview of all the teeth in the upper and lower jaws, allowing the doctor to see the angle and general position of the unerupted canines. If the panoramic x-ray reveals that a canine is severely angled, overlapping the roots of adjacent teeth, or positioned suspiciously high in the bone, a more advanced imaging technique is required.
This is where Cone Beam Computed Tomography, or CBCT, comes into play. A CBCT scan takes a highly detailed, three-dimensional image of the patient’s entire facial structure. This technology is utterly revolutionary for treating impacted teeth. It allows the doctor to virtually rotate the patient’s jaw on a computer screen to see the exact three-dimensional orientation of the impacted canine. The scan reveals whether the tooth is located on the cheek side or the palate side of the bone, exactly how close it is to the roots of the neighboring teeth, and whether any root resorption or cyst formation has already begun to occur. This extreme level of detail is what allows the orthodontic and surgical teams to formulate an exact, safe, and highly effective treatment plan.
Comprehensive Treatment Options for Impacted Canines
The strategy for treating an impacted canine depends heavily on the age of the patient, the exact position of the trapped tooth, and the amount of space available in the dental arch. The ultimate goal is always to guide the natural tooth into its correct position, preserving the patient’s natural bite and avoiding the need for extractions or artificial implants.
Early Interceptive Treatment
If an impending canine impaction is detected early enough, usually between the ages of eight and ten, it is often possible to intercept the problem before the tooth becomes hopelessly stuck. This phase of treatment is largely focused on creating enough physical space for the canine to drop naturally. The orthodontist may recommend the extraction of the primary baby canine. Removing this baby tooth clears the immediate physical barrier and often encourages the adult tooth to correct its own eruption path.
If space is severely lacking because the upper jaw is too narrow, the patient may be fitted with a palatal expander. This orthodontic device gently and gradually widens the roof of the mouth, expanding the perimeter of the dental arch and creating the precious millimeters of space required for the bulky adult canine to descend. In many cases, these simple interceptive measures are entirely sufficient to allow the canine to erupt naturally, completely eliminating the need for any future surgical procedures.
The Expose and Bond Surgical Procedure
When interceptive treatments are not an option, perhaps because the patient is older or the tooth is severely misaligned deep within the bone, a collaborative approach involving both an orthodontist and an oral surgeon is necessary. The gold standard treatment for this scenario is a surgical procedure known as an expose and bond. This meticulously coordinated treatment leverages the biological principles of bone remodeling to physically drag the impacted tooth through the jawbone and into the dental arch.
The process begins in the orthodontic clinic, where the patient is fitted with full upper and lower braces. The braces are used to align the visible teeth and physically open up a gap in the exact spot where the canine is supposed to eventually sit. Once there is sufficient space prepared, the patient is referred to an oral surgeon. Under local anesthesia, and often with the addition of mild sedation to ensure total comfort, the surgeon makes a small, precise incision in the gum tissue to expose the hidden crown of the impacted canine.
Once the tooth is visible, the surgeon must ensure the surface is completely dry and free of blood or saliva. They then use specialized dental adhesives to bond a tiny orthodontic bracket directly onto the surface of the newly exposed tooth. Attached to this bracket is a very small, delicate gold chain. The surgeon carefully loops the other end of this gold chain around the archwire of the patient’s braces, temporarily securing it in place. The gum tissue is then sutured back up, sometimes leaving the chain exiting through a small opening in the gums.
After a brief healing period of about two weeks, the patient returns to the orthodontist to begin the actual movement of the tooth. The orthodontist attaches a specialized elastic thread or a tension spring to the gold chain, linking it to the main archwire of the braces. This applies a very gentle, continuous, and highly controlled pulling force on the impacted canine. Over the course of several months, this delicate tension triggers specialized cells in the bone called osteoclasts to dissolve the bone in the path of the tooth, while osteoblasts build new bone behind it. Slowly but surely, the canine is guided out from deep within the jaw, through the gum tissue, and into its rightful place in the smile.
Extraction and Prosthetic Replacement
While the absolute priority is to save and reposition the natural canine, there are rare, extreme cases where this is biologically impossible. If a canine is ankylosed, meaning its root has permanently fused directly to the surrounding jawbone without the protective layer of the periodontal ligament, it will absolutely not move, regardless of how much orthodontic force is applied. Alternatively, if a patient waits until well into their adult years to seek treatment, the chances of successfully moving an impacted tooth decrease significantly, as the bone is much denser and the biological response to orthodontic force is dramatically slower.
In these rare circumstances where the tooth simply cannot be salvaged, the only viable medical option may be the surgical extraction of the impacted canine. Because leaving an empty gap in the mouth will lead to severe bite collapse and the shifting of all surrounding teeth, the extracted canine must be replaced. This is typically achieved through the placement of a titanium dental implant, which acts as an artificial root, topped with a custom fabricated porcelain crown. While modern dental implants are remarkably lifelike and functional, any dental professional will attest that keeping your natural tooth is always the superior outcome whenever clinically possible.
What to Expect During the Recovery Process
For patients undergoing the expose and bond procedure, understanding the recovery phase is essential for peace of mind. The surgery itself is a routine outpatient procedure, typically taking less than an hour per tooth. Because the oral surgeon uses precise, localized techniques, the post-operative discomfort is generally quite manageable. Patients can expect some mild swelling, minor bleeding, and tenderness around the surgical site for the first few days.
Managing this discomfort usually involves nothing more than over the counter pain relievers and the application of an ice pack to the outside of the face during the first twenty four hours. It is critical for patients to adhere to a very soft diet during the initial healing phase to avoid irritating the surgical site or accidentally dislodging the newly attached bracket and gold chain. Foods like smoothies, yogurt, mashed potatoes, and cool soups are highly recommended.
Maintaining immaculate oral hygiene is arguably the most important aspect of the recovery. The mouth is full of natural bacteria, and keeping the surgical area clean prevents infection and promotes rapid tissue healing. Patients will typically be instructed to gently rinse their mouth with warm salt water several times a day. While it is important to continue brushing the rest of the teeth normally, patients must be incredibly gentle when brushing near the exposed tooth and the gold chain. Once the initial surgical healing is complete, the subsequent orthodontic visits to tighten the chain will feel very similar to a standard braces adjustment, characterized by a few days of dull pressure as the tooth actively moves through the bone.
Why You Should Not Leave Impacted Canines Untreated
It can be tempting for a patient who is experiencing absolutely no pain from an impacted canine to simply ignore the problem and avoid the necessary treatment. However, leaving a highly developed tooth buried inside the jawbone carries immense long term risks that extend far beyond a cosmetic gap in the smile. One of the most severe and common consequences of an untreated impacted canine is the root resorption of adjacent teeth.
As the buried canine instinctively tries to push its way out of the bone, the crown of the tooth can press forcefully against the delicate roots of the neighboring lateral incisors or the central incisors. This constant, heavy pressure causes the body to physically dissolve and eat away at the roots of those otherwise perfectly healthy teeth. Over time, the roots of the incisors can become so severely compromised and shortened that the teeth become loose and eventually fall out entirely, turning a single tooth problem into a catastrophic multiple tooth loss scenario.
Furthermore, the follicular sac that naturally surrounds the crown of the unerupted canine during its development can sometimes mutate and fill with fluid, creating a dentigerous cyst deep inside the jawbone. If left unchecked, these cysts can grow to a massive size, hollowing out the surrounding bone, destroying the jaw structure, and displacing other teeth. Removing a large cyst often requires extensive, invasive surgery and can lead to permanent nerve damage. Even in the absence of cysts or root resorption, an impacted canine means the baby tooth will eventually fall out on its own, usually during the patient’s twenties or thirties, leaving a large, unsightly gap in the front of the mouth and causing the entire bite to collapse inward. The preventative nature of orthodontic and surgical intervention is vastly preferable to dealing with these severe long term consequences.

Frequently Asked Questions About Impacted Canines
What is the best age to treat an impacted canine?
The optimal time to address an impacted canine is during early adolescence, typically between the ages of eleven and fourteen. During this developmental window, the jawbone is still relatively soft and pliable, and the tooth is biologically primed to erupt, making orthodontic movement much faster and highly predictable. However, early interceptive evaluations should begin at age seven to prevent the impaction from worsening in the first place.
How long does the expose and bond process take to work?
The total duration of treatment varies drastically depending on how deeply the tooth is buried and the angle at which it is trapped. On average, it can take anywhere from six to twelve months of active orthodontic traction to slowly pull the canine out of the bone and bring it down into the correct alignment with the rest of the teeth. This is usually part of a broader braces treatment that lasts eighteen to twenty four months.
Is the surgery for an impacted canine painful?
The surgical procedure itself is performed under local anesthesia, so the patient will not feel any sharp pain while the doctor is working. After the anesthesia wears off, it is completely normal to experience mild to moderate soreness, swelling, and localized discomfort for a few days. This post operative discomfort is generally very easily managed with over the counter pain medication and cold compresses.
Can Invisalign be used to move an impacted canine?
While clear aligner therapy has advanced incredibly in recent years, severe impactions that require an expose and bond procedure generally rely on traditional fixed braces to supply the precise, heavy directional forces needed to pull a tooth out of the bone. However, in some highly specific, mild cases, orthodontists can utilize clear aligners in conjunction with special cutouts and elastics, though traditional brackets remain the gold standard for severe cases.
What happens if I choose not to treat my impacted tooth?
Choosing to leave an impacted canine untreated is highly discouraged by dental professionals. The trapped tooth can begin to resorb and destroy the roots of your healthy neighboring front teeth, potentially causing them to fall out. Additionally, untreated impacted teeth carry a significant risk of forming destructive cysts within the jawbone, which can lead to severe structural damage and require invasive reconstructive surgery later in life.
Can adults successfully undergo treatment for impacted canines?
Yes, adults can undergo treatment, but the process is notably more challenging than it is for teenagers. As a person ages, the jawbone becomes extremely dense, and the biological mechanisms that allow teeth to move slow down considerably. There is a higher risk that an adult tooth may be fused to the bone, meaning it will not move despite orthodontic traction. If movement fails, the alternative is usually extracting the impacted tooth and placing a dental implant.
