Ha ha ha!
Hopefully I won't ever have to take my teeth with me in a cup when I go to get them cleaned...the hygienist said they were in good shape, but I don't believe her. They may be healthy but I need a root canal in a bad way and I actually chipped the front one a couple of months ago and if I'm not careful it'll cut my lip on the inside!
I actually haven't seen the dentist in years, just the hygienist...she cleans them and sends me on the way every six months. They're less than a mile away, however and I don't have anything I have to pay out of pocket. And it's fast.
Well... if you could put them in a cup, you could just put them in the dishwasher and clean 'em yerself. :-)
