I use a regular toothbrush ( I get the kid-size to save weight), floss and no toothpaste. I used to use toothpaste and not spit it out so that I wasn't polluting the environment, but then I found out it's bad to ingest the flouride in the toothpaste, and besides it comes out eventually, right? So now I jsut skip the toothpaste and brush extra thoroughly, and floss as well.
