Impacted Teeth Traction
Helping Blocked Teeth Reach Their Proper Position
Dr Yvan Gaudex
Sometimes, instead of growing naturally into the mouth, a tooth remains trapped in the gum or bone. This is known as an impacted tooth. The condition most commonly affects upper canines but can also involve other teeth such as incisors, premolars, or certain molars.
With coordinated care between the dental surgeon and the orthodontist, it is possible to gradually guide the impacted tooth into its correct position using a technique called orthodontic traction. In some cases, this approach avoids extraction and preserves the natural tooth.
What Is an Impacted Tooth?
A tooth is considered impacted when it has formed but has not grown into the mouth. It may be:
- Fully embedded in the alveolar bone, requiring surgical access
- Covered only by gum tissue, making it invisible in the mouth
- Blocked due to lack of space, physical obstacles (other teeth, cyst, malformation), or unfavorable angulation
The teeth most frequently affected are:
- Upper canines, due to their complex eruption path
- Less commonly, lateral incisors, premolars, and certain molars such as wisdom teeth
Without treatment, impacted teeth may cause:
- Misalignment of the dental arch
- Resorption of neighboring roots due to mechanical pressure
- Malalignment of teeth or esthetic concerns
Psychological discomfort from a visibly missing tooth
What Does Impacted Tooth Traction Involve?
The treatment of impacted teeth generally includes two complementary steps:
Step 1: Surgical Exposure
The dental surgeon performs a minor procedure under local anesthesia to:
- Access the impacted tooth by uncovering the gum tissue
- Expose part of the tooth crown
- Bond an orthodontic attachment (button or bracket) onto the tooth
In some cases, limited bone removal is necessary. The incision is then closed while leaving sufficient access for orthodontic traction.
Step 2: Orthodontic Traction
The orthodontist uses the bonded attachment to apply gradual force with elastics, orthodontic chains, or fixed appliances. This gently guides the tooth into its correct position within the arch, while preserving surrounding tissues.
The duration of treatment varies depending on several factors: depth of impaction, tooth angulation, bone density, patient age, and oral hygiene. It generally lasts from a few months to about a year.
Benefits of This Technique
Impacted tooth traction allows:
- Preservation of the natural tooth whenever possible
- Closure of the space left by the unerupted tooth and restoration of alignment
- Improved chewing function and occlusion
Reduced risk of complications linked to untreated impacted teeth (tooth displacement, root damage, infections)
Is It Painful?
The surgical procedure is performed under local anesthesia, ensuring comfort during the intervention. Post-operative effects may include:
- Mild discomfort or pain for a few days
- Localized swelling, sometimes with minor bruising
These effects are usually well controlled with prescribed pain relievers and recommended hygiene measures.
Orthodontic traction may cause a sensation of pressure or tension on the tooth, but rarely significant pain.
Who Can Benefit From This Treatment?
Impacted tooth traction may be suitable for:
- Children or adolescents, as part of comprehensive orthodontic treatment
- Selected adults, depending on the position and condition of the tooth
Each case is evaluated through clinical examination and imaging (panoramic X-ray, 3D scan) to assess feasibility and establish a treatment plan.
CONCLUSION
Orthodontic traction of impacted teeth can, in many cases, reintegrate a blocked tooth into the dental arch and avoid extraction. This treatment requires close collaboration between the dental surgeon and the orthodontist and is based on a personalized, carefully planned approach.
