So really, how does this ditzy blonde Neocola addict, Sierra Petrovita still have her teeth? I wonder this about many of the inhabitants of the wastes actually. Given that no toothbrushes or toothpaste seem to exist, and brushing with abraxo cleaner seems a bit harsh, not to mention toxic. I assume maybe they can use some rubbing alcohol as mouthwash maybe...? They can't do like the ancient Romans did, and use cat piss, since all cats are recorded as dead. And I can't see what they would floss with! Though I assume string or something of that nature.
I honestly feel that tooth pain would be a major issue in the wasteland though.
