Why use water to clean teeth at all? I don't (...and no crack about
using whisky, please). Apply toothpaste to dry brush, brush teeth,
spit into sink, then wash remains away with a small amount of water,
also used to rinse brush, which is then air-dried. Do twice daily after
meals.

I started doing this after visiting Africa and seeing at first hand
what people had to go through to get 'water' - actually muddy polluted
muck - to use for drinking, cooking and cleaning; then learning how
much water is wasted by people leaving taps running while brushing
teeth during a not-so-recent water shortage.

On my recent visit to a dentist, he complimented me on my teeth, and
expressed surprise that I hadn't seen a dentist for over 10 years - my
teeth were as good as those who had regular 6-monthly check-ups. I
simply needed a 25-year old filling replaced.

Frankly, I'd be more concerned about what lives on the average
toothbrush.
