Are black rotting teeth a sign of meth use?
I saw a pic from an old friend on FB and noticed some of her teeth are starting to look black and rotting. I'm concerned maybe she's gotten into meth now. It started as just a dark stain between her teeth that I thought was from smoking, but now her teeth are starting to look chipped and rotten. Is this a sign of meth use? I know it's her choice but she's been through a lot and I'm worried about her and hoping she isn't turning to drugs.
