Impacted Canines
An impacted tooth simply means that it is "stuck" and cannot erupt into function. The maxillary (upper jaw) cuspid, commonly known as the eyetooth, is the second most common tooth to become impacted after wisdom teeth.
Why the Cuspid Tooth Is Critical
The cuspid (canine) tooth plays an essential role in the dental arch:
- •Strongest biting teeth with the longest roots of any human teeth
- •Guides your bite: designed to be the first teeth that touch when your jaws close together, guiding the rest of the teeth into proper alignment
- •Anchors the dental arch: critical for both function and facial aesthetics
When Does Impaction Occur?
Most of the time, maxillary cuspid teeth are the last of the "front" teeth to erupt into place, typically around age 13. When a cuspid tooth becomes impacted (usually identified by the orthodontist during routine evaluation), every effort is made to guide it into its proper position in the arch.
Common signs of impaction include:
- •Failure of the canine to appear at the expected age
- •Abnormal positioning detected on dental X-rays
- •Retained baby (deciduous) canine tooth beyond age 13
- •Visible or palpable bump in the palate or above the gum line
Diagnosis & Advanced Imaging
Accurate localization of the impacted canine is essential for treatment planning:
- •Panoramic X-ray for initial screening to identify impaction
- •3D CBCT imaging: cone-beam computed tomography provides precise three-dimensional location of the impacted tooth relative to surrounding teeth and structures
- •VR surgical rehearsal: in complicated cases, Virtual Reality technology allows Dr. Krajekian to visualize the impacted tooth in an immersive 3D environment and plan the optimal surgical approach
Treatment: Surgical Exposure & Orthodontic Eruption
The technique to aid eruption is straightforward, performed in close coordination with the patient's orthodontist:
Step 1: Surgical Exposure
The gum tissue overlying the impacted canine is lifted to expose the hidden tooth. A small orthodontic bracket and gold chain are bonded to the exposed tooth.
Step 2: Guided Eruption
The orthodontist attaches the chain to the braces and applies gentle traction over several months. The impacted canine is slowly guided into its proper position in the dental arch.
Step 3: Final Alignment
Once erupted, the orthodontist completes final alignment and bite adjustment. The result is a naturally positioned, fully functional canine tooth.
What to Expect
- •The procedure is typically performed under local anesthesia or IV sedation
- •Recovery involves 3-5 days of mild swelling and discomfort
- •Orthodontic eruption phase takes several months
- •Success rates are excellent when identified and treated at the appropriate age
When Advanced Technology Is Needed
While the surgical technique is straightforward in most cases, some impacted canines present unique challenges:
- •Deeply impacted teeth requiring precise localization
- •Proximity to adjacent tooth roots requiring careful surgical planning
- •Unusual angulation that complicates the approach
In these complex cases, Dr. Krajekian uses 3D CBCT imaging and VR surgical rehearsal to plan and execute the safest, most effective approach.
Key Benefits
- •Preserves the natural canine tooth
- •3D CBCT imaging for precise localization
- •VR surgical rehearsal for complex cases
- •Close coordination with orthodontist
- •Minimally invasive surgical exposure
- •Excellent long-term success rates
Recovery Time
3-5 days initial; several months for orthodontic eruption
