Vertical wisdom teeth are better to be extracted, but it is still necessary to consider various factors such as the number of roots, the direction of root growth and the distance from the nerve, and it is not possible to make a direct judgment.
Vertical impaction means that the long axis of the wisdom tooth is parallel to the long axis of the surrounding normal teeth, and there is no crookedness or lateral impaction. The difficulty of removing a vertical wisdom tooth is slightly lower than that of a horizontal wisdom tooth or an inverted wisdom tooth, provided that the roots, nerves, and skeletal tissues of the teeth are the same.
However, the difficulty of removing vertical wisdom teeth cannot be directly determined, as the number and direction of the roots of the wisdom teeth are not exactly the same, so an increase in the number of roots or a skewed direction of root growth may also make the removal of vertical wisdom teeth more difficult. It is also significantly more difficult when the wisdom teeth are in close proximity to the dental nerve, and nerve damage is more likely to occur during surgery.
Wisdom teeth should be removed with X-rays for preoperative evaluation, and should be prepared under the guidance of a physician to determine if they are suitable for extraction.
