I think you’re thinking of their prison system.

Lots of ppl saying they’ll just go to bed without brushing. My guess is you haven’t been a financially struggling human and had to pay for lots of dental work out of pocket. Not to mention the pain and inconvenience of the procedures and healing. Paying a lot of money to have a healthy functioning mouth puts things in perspective sometimes. Anyway, I also do this to prevent myself from snacking. Hope others can be if it from the tip.
