Wisdom tooth extraction
Wisdom tooth, also known as third molar, normally is the last tooth in the jaw. Some people are lucky to have wisdom teeth erupted and function normally, but a lot of wisdom teeth are trouble makers. They may have decays themselves or cause decays on adjacent teeth, cause gums or other soft tissue inflammation, have cysts or other pathology lesions. These are the most common reasons why wisdom teeth need extractions. However, there is no evidences showing they push teeth forward and cause teeth crowding.
This case showed that a horizontally impacted wisdom tooth caused food impaction. It would cause decays on itself and the tooth in front it, which meant that both teeth might need to be extracted. The wisdom tooth was surgically removed before any damage on the adjacent tooth. The healing was fast and uneventful.
