Wisdom teeth that are definitively blocked in the lower jaw cannot be orthodontically corrected, and there is no need to do so. Because itself determined obstructed wisdom teeth, first of all, has no hope of eruption, 2nd, wisdom teeth obstruction often means that the jawbone in the mouth has no normal space for the eruption of wisdom teeth. Since we are chewing more and more fine and soft food nowadays. So our jawbone development is much lower than that of the ancient people. From this point of view, our own tooth volume is on the high side. As the last tooth to erupt, wisdom teeth often do not have space to erupt, resulting in wisdom teeth obstruction. The clinical recommendation is to remove the obstructed wisdom teeth as soon as possible, because if the obstructed teeth are not removed, bacteria and food residues may be retained around the wisdom teeth, resulting in pericoronitis, so the obstructed wisdom teeth are not worth correcting. In the case of children who are in the period of tooth replacement, if the 1st molar is lost prematurely, then an orthodontic solution can be considered to tract the 2nd molar and wisdom teeth behind to the front.
