Corvo emerged with a pile of clothes, towel and a toothbrush perched on top in time to hear Tramp's question. "Well, there's two answers to that question. Do you have to? No. Should you? Yes. Actually a lot of people brush twice a day, in the morning and at night before they go to bed. Cuts down on the bad breath and helps protect the teeth from rotting and falling out."
He held out the pile he was holding. "You'll also notice the difference in how food tastes. A clean mouth means your tastebuds aren't picking up the muck on your teeth and tainting the food." He suddenly grinned. "Just don't brush your teeth then drink orange juice. The version of toothpaste is made very differently here and those two things don't mix. I learned that one the hard way."
