Generally speaking, the numbness of the lower lip and chin after tooth extraction is because the teeth of the lower jaw have been removed, so such problems may occur, and the treatment methods are as follows: 1. Because the anesthetic power has not yet gone down after the doctor has played the anesthetic, you need to wait quietly for the anesthetic power to go down slowly, and the symptoms of numbness of the lower lip or numbness of the chin will gradually disappear. However, during the waiting process, you must not eat anything too hot or bite your lower lip with your teeth, at this time, if you bite your lower lip or eat something too soupy, it is likely to cause some damage to your lower lip, because you can’t feel it when you bite it or burn it; 2. All these drugs need to be prescribed by professional clinicians to guide how to use the drugs, never take the drugs by yourself, or carry out some blind treatment.
