A recent story in the Grimbsy Telegraph titled “£15,000 payout after dental op leaves Grimsby woman with permanent numbness,” describes how a 39 year old woman who had 2 wisdom teeth extracted was left with nerves in her lower jaw severed. The article was written on October, 6, 2012 and is located at http://www.thisisgrimsby.co.uk/15-000-payout-dental-op-leaves-Grimsby-woman/story-17045539-detail/story.html.
The woman says her lip turns completely blue in the cold and, at times, she bites her lip without realising until it starts to bleed. She also says
“I can be having a drink or eating food and without realising I am dribbling…It is embarrassing when my children have to tell me to wipe my chin as I have food on it, or they tell me to speak properly because my speech is affected.”
The woman was awarded £15,000 in an out of court settlement which is a bit less than $25,000 USD.
As is discussed over at http://www.teethremoval.com/complications.html cases of permanent nerve damage unfortunately due happen. Also see http://www.teethremoval.com/dental_malpractice.html for some other cases and settlements from permanent nerve damage after having wisdom teeth extracted.
