Long story short, my brother just got out of the hospital from intestinal surgery about 3 weeks ago. Currently on antibiotics (Augmentin). He is having problems and infection is being suspected (he's probably going to be readmitted this week).
Two days ago, his teeth turned gray. Almost a clear, translucent gray. He is not eating or drinking anything that would turn his teeth gray. Does anyone have any idea why teeth would turn almost translucent gray?
