Hello,I had 4 wisdom teeth removed yesterday at 8am.  Its now 4pm and my bottom lip, from the corners of both sides of my mouth, my gums/teeth and my chin are still numb.  I feel a tingly sensation when I touch my chin and can feel heat and cold on my chin.  How long would you expect the numbness to last?  Is there anything I can do to speed up the process of getting the numbness to go away.  I have read other posts that say that only time will tell, but this is seriously driving me crazy.  Any suggestions and or information would be much appreciated.
Thanks for your query, I have gone through your query. The numbness(anesthesia or paresthesia) can be because of the pressure over the nerve by a wisdom tooth during extraction. The other possible cause can be any injury to the nerve by trauma or any injection at the site of nerve. Nothing to be panic, consult an oral physician and get yourself examined and take a screening radiograph like OPG to rule out the above said causes.Meanwhile you can take a nerve regenerating Chat Doctor.  Take care of the part which is numb from hot, cold and sharp objects, because you will not be able to make out the sensation. This might take weeks to months for complete recovery. I hope my answer will help you, take care.
