To determine whether the wisdom teeth that have not yet grown out need to be extracted, curved tomographic x-rays should be taken to determine whether the growth direction and growth position of the wisdom teeth are normal. If the wisdom tooth is growing upright and there is enough room for eruption on the film, it can be withheld and observed for the time being. If the wisdom tooth is growing horizontally and at an angle, this kind of obstructed growth can be seen on the film, and there is not enough space to fully erupt into the mouth. For this kind of obstructed wisdom tooth, it should be extracted as soon as possible even if it is not fully erupted. If the wisdom tooth has not fully erupted, it is usually because the root of the wisdom tooth is not fully developed and it is relatively easy to remove the wisdom tooth at this time. There is also a case where the wisdom teeth are completely blocked, which is a lower position and more risky to remove, but it is also recommended to remove them as soon as possible.
