question: 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.
