I had this discussion with about a fifty peeps one day. Do you wet the tooth brush first or go for it dry??? For me, it's wet all the way.
50/50 if i'm gonna take a shower, then the toothbrush is wet. other than that, i start brushing my teeth in my room as i walk to the bathroom.
It actually makes more sense to wet before toothpase because after toothpaste the water would just roll right off the brush. I might consider changing my habits...
