###Human: I have extracted my left upper wisdom tooth. Should I need to extract left lower wisdom tooth? ###Assistant: Hi. If you have sensitivity on your wisdom tooth, you should re-evaluate the filling. However, if it is not severe and increasing in nature, please wait for sometime, and it can subside on its own. The presence of wisdom tooth will not interfere with the braces treatment. Usually, when the upper wisdom tooth of the same side is removed, it is advisable to remove the lower also, because without any opposing upper tooth, it is impossible to bite and it can cause supra eruption causing other problems. But it can be removed at the time if it causes trouble. It is not a mandatory procedure at this time.
