Hello, i recently got hit with a piece of hardwood flooring that flew off of a table saw i was using.It hit me in the chin,from the top of my bottom lip to the very end of my chin,split wide open and went all the way through.It knocked out my top left big tooth and i have many stitches outside and inside of my mouth,it roughed up my gums under my teeth quite a bit also.My question is....my bottom row of teeth are still intact(thank god) but are very very numb.They dont hurt but are very very sensitive.It has been 4 days since the accident.The doctor told me it will take some time to determine if my nerves were damaged and if i will need further care in the future.What could have happend to them,best and worse case scenario..Thanks!!...Jay
