What Is an Impacted Canine?
An impacted canine is a permanent canine tooth that has failed to erupt into its correct position in the dental arch. It remains trapped within the jawbone, either on the palatal (roof-of-mouth) side or the labial (lip) side. Upper canines are the most frequently impacted teeth after wisdom teeth, affecting roughly 2% of the population, and palatal impaction is about twice as common as labial impaction. The lower canines can impact as well, but do so far less often.
Canines have the longest and most tortuous eruption path of any tooth — they form high in the maxilla near the floor of the eye socket and travel a long, winding route before dropping into place between the lateral incisor and the first premolar. That long path gives the canine more opportunity to deviate, become blocked by the root of a neighboring tooth, or lose its way. Bold Bite sees impacted canines at every stage — in children whose eruption pattern is still unfolding, in teens whose baby canine never fell out, and in adults who had the problem their whole life and finally decided to address it.
Why Canine Teeth Are Worth Saving
Unlike wisdom teeth, which are routinely extracted, canines serve essential functions that cannot be easily replaced. Bold Bite's default starting position is therefore to guide the impacted canine into the arch rather than remove it.
Bite guidance. Canines steer the jaw during lateral (side-to-side) movement. This is called canine guidance: when the jaw shifts sideways, the canine is the only tooth that contacts, which protects the back teeth from damaging lateral forces. Without a functioning canine, the molars and premolars absorb forces they were never designed for, and show it over years as flattened cusps, cracks, and wear facets.
Smile aesthetics. The canine forms the “corner” of the smile arc — the transition between the flat front teeth and the rounded back teeth. A missing or malpositioned canine creates a visible asymmetry that is difficult to mask with a replacement tooth, and the premolar that would otherwise be substituted has a markedly different color, contour, and width.
Root strength. Canines have the longest roots of any tooth, anchored deep in the bone. They provide structural support to the arch and are typically the last teeth a person loses to periodontal disease. That long root is exactly why a natural canine, once guided into position, outlasts any prosthetic alternative.
This is why the default goal at Bold Bite is to guide the impacted canine into position rather than extract it. Guided eruption is not always the best path, though — the right call depends on where the canine sits in the bone, the patient's age, and the complexity of the case. The next section explains when premolar substitution is the better choice.
The Bold Bite Approach to Impacted Canines
Impacted canines illustrate how Bold Bite Orthodontics coordinates care rather than trying to do every part of a complex case in-house. The orthodontic side — space creation, bracket placement, gold-chain traction, and guided eruption — is handled by Dr. Greenberg and Dr. Cao at the Jacksonville office. The surgical exposure itself is handled by Dr. Doug Stortch at Modern Perio, a long-standing partner practice, with Jacksonville-area oral surgery available as a backup for the cases that need it.
Bold Bite's preferred surgical technique depends on where the canine sits. Palatally impacted canines are typically managed with an open exposure, which leaves the gum tissue open so the tooth can be pulled straight down into the palate. Facially impacted canines are managed with a closed exposure and a gold chain or IsoGlide attachment, which keeps the gum line tidy and protects the final aesthetic result on the buccal surface. Either way, exposure cases typically add six to eight months to the total treatment timeline, and the practice sets that expectation up front rather than discovering it mid-case.
Dr. Cao's CAGS training — a two-year certificate of advanced graduate study in orthodontics beyond the standard MS — makes her the lead orthodontist on Bold Bite's more complex impacted-canine and surgical-orthodontic cases. Dr. Greenberg's background in general dentistry before specializing means the restorative and periodontal implications of each option are weighed at the same table. Complex cases are case-conferenced between both doctors before a recommendation is made.
Expose-and-Bond vs. Premolar Substitution
When Premolar Substitution Makes Sense
Extracting the impacted canine and moving the first premolar forward into the canine position can shorten treatment significantly and produce an excellent result — but the decision has to be weighed carefully because it trades a long-rooted canine for a shorter-rooted premolar. Bold Bite considers premolar substitution when:
- The impacted canine is severely displaced — high in the bone, at a steep angulation, or in close proximity to the roots of adjacent teeth where traction poses a high risk of root resorption on the neighbor.
- The patient is an older teen or adult in whom the likelihood of successful guided eruption is reduced and the treatment time for expose-and-bond would become excessively long.
- The first premolar has favorable anatomy — a single cusp tip that can be reshaped to mimic canine contour, a root that supports group function if canine guidance cannot be established, and a color that blends naturally with the lateral incisor.
- The canine shows radiographic signs of ankylosis (fusion to the bone), which prevents orthodontic movement entirely.
When Expose-and-Bond Is Preferred
For most children and younger teens, preserving the natural canine produces a better long-term result. Expose-and-bond is the preferred path when:
- The canine is in a favorable position (moderate angulation, reasonable depth, clear distance from the roots of adjacent teeth).
- The patient is young enough that the bone remodels readily and traction has a high success rate.
- Preserving the natural canine provides superior long-term function — the canine root is longer and stronger than the premolar, canine guidance protects the posterior teeth, and the natural tooth outlasts any prosthetic replacement.
An Honest Conversation at Consultation
Dr. Greenberg and Dr. Cao review the CBCT scan together on screen with the family to show the canine's exact position, angulation, depth, and proximity to adjacent roots. Both options are presented honestly — the long-term benefits of saving the natural canine weighed against the added treatment time and surgical step, versus the faster, simpler path of extraction with premolar substitution. Bold Bite's role is to lay out the evidence clearly; the family decides which path fits their situation.
Early Detection: The Age 9–10 Window
The single most important factor in impacted-canine outcomes is early detection. At age 9 or 10, the permanent canine is developing high in the maxilla but has not yet fully committed to an eruption path. A panoramic x-ray at this age can identify canines that are angled toward the root of the lateral incisor or tipped toward the palate — the classic ectopic pattern — before they become truly impacted. Bold Bite builds this check into its Phase 1 evaluation as part of the standard AAO age-7 screening window.
Interceptive Approach: Primary Canine Extraction
Published research shows that extracting the baby canine at age 10 or 11 — at the moment the permanent canine is developing on an ectopic path — removes the obstruction and allows the permanent canine to self-correct its eruption in 62 to 78% of palatally impacted cases. This simple extraction, combined with palatal expansion when the arch is narrow, often eliminates the need for surgical exposure entirely. It is the clearest payoff for early orthodontic screening: a ten-minute baby-tooth extraction in the fourth grade can save a surgical procedure and a year of orthodontic traction in the eighth grade.
What Bold Bite Checks at Consultation
Palatal palpation. At every child consultation, the doctors palpate the palate and labial vestibule to feel for the canine bulge — a small, firm bump that indicates the canine is on track in the bone. If the bulge is absent on one side past age 10, further imaging is warranted even when everything else looks normal.
CBCT 3D localization. When an impacted canine is suspected, the Bold Bite Vatech Green cone-beam CT shows the exact position of the tooth in three dimensions — its angulation, depth, proximity to adjacent roots, and whether it is palatal or labial. Published studies show that CBCT-guided treatment planning reduces overall treatment time by roughly four months compared to conventional 2D imaging and increases clinician confidence in the surgical approach. Bold Bite includes the CBCT as part of the comprehensive exam for suspected impaction cases.
What Happens If an Impacted Canine Is Not Treated
Root Resorption of Adjacent Teeth
The most serious consequence. An impacted canine pressing against the root of the lateral incisor can resorb (dissolve) that root from within the bone — silently, with no symptoms. By the time it is detected clinically, the lateral incisor may be unsalvageable. This is the quiet damage that 2D panoramic films routinely miss; CBCT imaging picks it up when it is still reversible. Bold Bite flags suspected resorption at the diagnostic stage and, when present, accelerates the treatment plan to protect the neighboring tooth.
Cyst Formation
A dentigerous cyst can develop around the crown of an impacted tooth. While usually benign, cysts expand over time and can damage surrounding bone and teeth. Early diagnosis keeps the cyst small and manageable.
Loss of the Baby Canine
The retained baby canine will eventually lose its root to resorption and fall out — typically in the late teens or twenties — leaving a gap with no permanent tooth waiting underneath. A permanent gap at the corner of the smile is always visible and is substantially more difficult to close later than it is to resolve during active growth.
Arch Integrity
Without the canine, adjacent teeth drift into the empty space, creating spacing and bite problems that become progressively more difficult to correct. The molars rotate forward, the lateral incisor tips sideways, and the occlusion loses the canine-guided protection it depends on for long-term stability.
The Impacted Canine Treatment Process at Bold Bite
3D imaging determines the exact position, angulation, depth, and relationship to adjacent roots. This guides the surgical approach and the direction of orthodontic traction.
Braces are placed and the teeth are aligned to create a gap in the arch where the canine belongs. If the arch is narrow, palatal expansion may be needed first. The baby canine is extracted if still present.
An oral surgeon lifts the gum tissue, removes any overlying bone, and bonds an orthodontic bracket with a small chain onto the impacted canine. Closed technique (gum replaced) or open technique (gum left open) is chosen based on the tooth's position. Takes approximately 1 hour under local anesthesia.
Dr. Greenberg uses the chain to apply light, slow traction, gradually guiding the canine through the bone and into its correct position over 6–12 months. Force must be light to avoid ankylosis (tooth fusing to bone) or root resorption.
Once the canine has erupted into the arch, comprehensive braces fine-tune its position, establish proper canine guidance, and align the rest of the teeth. Total treatment: 18–30 months.
Why Bold Bite Handles Impacted Canines Carefully
Impacted canines are one of the most case-dependent problems in orthodontics. The right answer in a fourth-grader with a palatal ectopic is almost never the right answer in an adult with a labially displaced, nearly ankylosed canine. Bold Bite handles these cases carefully because of three practice-level choices that shape every impacted-canine treatment plan.
Two specialist perspectives on every complex case
Dr. Greenberg and Dr. Cao are a husband-and-wife orthodontist team in one office. Every impacted-canine case is case-conferenced between them before a recommendation goes to the family — one specialist’s read on angulation, root proximity, and traction risk is double-checked against the other’s. Dr. Cao’s CAGS training at Jacksonville University makes her the lead on the practice’s most complex surgical-orthodontic cases, including impacted-canine cases with adjacent-tooth resorption risk.
A long-standing surgical partnership, not a referral lottery
Surgical exposure is only as good as the surgeon performing it. Bold Bite refers its exposure cases to Dr. Doug Stortch at Modern Perio as the primary surgical partner, with Jacksonville-area oral surgery as a backup. Using the same surgeon across most cases means the orthodontic-to-surgical handoff is predictable: the bracket placement, chain direction, and exposure technique are coordinated up front, and the Bold Bite orthodontic team can start traction at a known time after surgery rather than waiting weeks for communication.
A full-mouth view of the decision
Dr. Greenberg practiced general dentistry for eight-plus years before specializing in orthodontics. That background drives how Bold Bite weighs the save-versus-substitute decision: the restorative implications of a premolar-in-canine position, the long-term periodontal health of the adjacent lateral incisor, the color match of the reshaped premolar, and the occlusal consequences of losing canine guidance are all part of the conversation at consultation. The recommendation is not a narrow orthodontic opinion; it is a whole-mouth one.

How Much Does Impacted Canine Treatment Cost?
Comprehensive braces (includes canine management): from $4500
Clear ceramic braces: from $4700
Surgical exposure: separate oral surgeon fee, typically $800–$1,500 per tooth
The practice coordinates directly with the surgeon for scheduling and insurance pre-authorization. Most dental insurance covers both the orthodontic treatment and the surgical exposure when medical necessity is documented (impacted tooth, risk of root resorption).
Insurance & Financing
In-house 0% APR: 0% interest, no credit check, and a down-payment amount set by the treatment type and insurance benefit. Monthly payments on the in-house plan start at $149 per month and run month-to-month for the length of active treatment. Cherry: soft-credit-check financing with flexible terms and a $189 typical down payment — useful for families who need a longer payoff window than the in-house plan offers. Pay in Full: a 5% discount off the total treatment fee for families who pay up front. Impacted-canine cases involve two fees — the orthodontic fee to Bold Bite and a separate surgical fee typically ranging from $800 to $1,500 per tooth to the oral surgeon. Insurance covers a portion of both for most PPO plans when medical necessity is documented (impacted tooth, risk of root resorption). Bold Bite verifies benefits before the consultation and applies the estimated benefit to the itemized quote. Community discounts apply to military families, teachers, public-safety personnel, and sibling cases.

Frequently Asked Questions About Impacted Canines
How do I know if my child has an impacted canine?
Check for asymmetric canine bulge, feel the palate near the gumline on both sides. If one side has a bump and the other doesn't, imaging is warranted. Also: baby canine still present after age 13, visible gap, or asymmetry between left and right. Panoramic x-ray at age 9–10 can identify ectopic canines early.
What happens if an impacted canine is not treated?
Root resorption of adjacent teeth (lateral incisor most at risk, silent, no symptoms until damage is severe), dentigerous cyst formation, eventual loss of the baby canine leaving a gap, and progressive arch collapse.
Can an impacted canine erupt on its own?
If caught early, extracting the baby canine removes the obstruction and allows self-correction in 62–78% of palatal cases. Once fully impacted, surgical exposure and orthodontic traction are needed.
What is the expose and bond procedure?
Oral surgeon lifts gum tissue, removes overlying bone, bonds a bracket + chain onto the impacted canine. Approximately 1 hour under local anesthesia. Orthodontist then uses the chain to guide the tooth into position over 6–12 months.
Is the surgery painful?
Done under local anesthesia with sedation available. Post-op discomfort is mild to moderate, generally less than wisdom tooth extraction. OTC pain medication for 2–3 days. Soft diet for one week.
How long does the entire treatment take?
18–30 months depending on canine position. Space creation: 4–8 months. Surgical exposure: 1 day. Traction and alignment: 12–18 months.
When is extraction the better option?
When the canine is in an extreme position, is ankylosed (fused to bone), or in older patients where guided eruption has a poor prognosis. The first premolar is substituted in the canine position and reshaped.
