How much water do you need to brush your teeth in litres?

Answer 1

You can save 2 to 3 quarts a minute, twice a day. This would be about 500 to 1200 gallons a year.

* Claims of 12,600 gallons saved per year are mathematically faulty - based on 4 gallons per minute for 3 minutes, 3 times a day. This rate of water flow is the rate for filling a bathtub!

Answer 2

1. You can be sure to turn the water off while your brushing, you usually only need water to wet the brush/toothpaste.

2. Don't wet the brush as much.

3. Don't turn the water on full blast, just a trickle will be fine.

Answer 3

It is recommended to brush your teeth for a minimum span of 3 minutes each time, and 3 times a day, or after every meal.

Anwer2: Most of the electric toothbrushes have a two minute warning buzz. OralB has a nice dialogue on brushing and flossing properly on their site.

Answer 4

Depends if you leave the tap running or not. If you turn the water on/off as you need it, it'll only be a cup or two. Leave it running and it can use up gallons.

*****

When cycle camping in the UK, I can brush my teeth using just one cup of water! At home I try to remember not to leave the tap running while I brush my teeth - not always successfully!

Answer 5

The minimum amount of water needed to brush your teeth is probably about 0.25L. That's a tad over one cup in the United States. All you need is enough water to moisten the brush with paste and to rinse your mouth and sink when done. Most people with indoor Plumbing use far more than that.

Answer 6

Most adults use about 2 gallons of water to brush their teeth.

Answer 7

Some dentists recommend brushing your teeth for 5 minutes after each meal. If you brush your teeth 3 times in one day, what fraction of the day do you spend brushing your teeth?

Answer 8

500 gallons
