I am not sure if you have seen a photo of Amy Winehouse when she was in rehab? There was one photo which is a closeup photo of her hideous teeth. Apparently, her teeth are dropping because of her gum diseases. I read that it is common in drug abuser. It is rather cruel to show her pictures all over the entertainment media but then, it is also a scary reminder that people who did not seek drug rehab may end up at the bottom of the pits.
I will not make Amy Winehouse already miserable publicity even much worse. So, Google it up if you are curious.
