Water is not wasted. It will flow back into the environment. So the answer is zero.
if it's going to the body then it's not waste.
about 50% is water
No, waste water requires much more complex cleaning.
too much
You waste about 10 gallons of water a day just for one person

A standard toothbrush typically weighs around 15 to 30 grams.
A dry toothbrush is already frozen, that is, solid. It becomes solid well above 100 Celsius, the boiling point of water. If the toothbrush gets too cold, near -40C, it may become "brittle" and snap. Of course if you store the toothbrush "wet" the water on the bristles will freeze near 0C, but will melt quickly under water.
about 30 gallons a day...
