According to the articles, Mercedes had her wisdom teeth removed in February, 2009. She began to feel a purple lump on her left temple along with pain and swelling. She saw the dentist for a follow up and told her he thought nothing was out of the ordinary. Eventually she had to be airlifted to a hospital because she was suffering from septic shock due to an infection that had developed and spread to her main arteries and organs. She had to undergo a surgery on her brain to remove a piece of skull and clean the infection. This surgery lasted 10 hours.
Due to the blood clotting she suffered from several strokes and remained in the hospital until May, 2009, a period of around 11 weeks.
She then remained in a rehabilitation center until October, 2009. She is now partially paralyzed in her right arm and leg and can only walk short distances. She is also learning to talk again and continuing to undergo physical therapy, occupational therapy, and speech therapy.
The reason for all of the problems following wisdom teeth removal is attributed to Lemierre’s Syndrome which rarely occurs after a wisdom tooth extraction. This disease is known to affect young and healthy adults. I recommend reading the Wikipedia article on Lemierre’s Syndrome to learn additional information.
