Impactions
Impacted wisdom teeth (i.e., those that have failed to erupt through the gum line) fall into one of several categories:
- Mesioangular impaction is the most common form (44%), and means the tooth is angled forward, towards the front of the mouth.
- Vertical impaction (38%) occurs when the formed tooth does not erupt fully through the gum line.
- Distoangular impaction (6%) means the tooth is angled backward, towards the rear of the mouth.
- Horizontal impaction (3%) is the least common form, which occurs
when the tooth is angled fully 90 degrees sideways, growing into the
roots of the second molar.
