Wisdom teeth usually erupt around the age of 18-20. Because wisdom teeth erupt, may produce a forward push on the front teeth, some patients will have incisor crowding problems, manifested in the past teeth are neat, wisdom teeth eruption after the incisor torsion is not aligned. Simply removing the wisdom teeth at this time cannot effectively solve the problem of crowded teeth, and even if the wisdom teeth are removed, the teeth will not be able to recover on their own. Because the eruption of wisdom teeth has caused crowding of the front teeth, the only way to effectively solve the problem of uneven teeth is to apply force to align them through orthodontics and other methods.
