He wouldn't have even needed the skin graft in the first place if the guy didn't completely screw up filling a cavity. He drilled a hole into my dads jaw, cause he had no idea what he was doing. He was a dentist in training and had never filled a cavity before.
Tell me about it, completely stupid situation. I understand everybody has to learn at some point but that dude was obviously not prepared in the slightest to fill a cavity.
