You can use as much water as you want when you brush your teeth. The amount varies from person to person.
65cl
it may take up to 1 gallon to brush your teeth. However, you should save water by using a glass, if you did that, you would use about a seventh of that.
It depends on the size of your mouth and how much tooth paste you use
It is recommended to wet your toothbrush before applying toothpaste and to rinse your mouth with a small amount of water while brushing. Overall, using a total of around 4-8 ounces (120-240 mL) of water for the entire teeth brushing process is usually sufficient.
If we used hot water to brush our teeth, we could burn our mouthes and the water doesn't clean the stuff in our mouth.

I use warm water and an 1/8 of a teaspoon of salt with a soft kids tooth brush. :-)
Some ways to use less water are, turn off the water when you brush your teeth, take a bath instead of a shower, and do not run to much water when you do take a bath!
shower,brush teeth, and clean dishes
Electric toothbrushes are brilliant! And so easy to use, I feel they do a much better job of cleaning your teeth. Hope this helps PY
