This is my worst nightmare. Going to the dentist for something simple and walking out with even more problems.

21-year-old Christopher Crist of Indianapolis claims that he went into a dentist office to get a few painful teeth pulled. When he walked out, he had none. They gave him pills and numbing shots for the pain and after they took out the three teeth, they just kept going.  They pulled out ALL of his teeth!

Christopher is autistic and his Mom say she has no idea how this happened.  When reporters went to the dental office looking for answers, they were turned away but did speak with other patients who said similar things had happened to them.
