I've noticed that many of you here do not brush your teeth on a Water Fast or either you do brush but do not use anything else other than plain water. During my fasts, I always brush regularly using toothpaste. I hope that does not badly interfere with the fast; I just feel the need to use a tongue scraper and brush well afterward, I like feeling completely fresh. Maybe this is why my fast tend to end short? Had not thought of this before.
