Teeth, sometimes called hard, bitey mouth rocks, need to be cleaned three times a day due to the fact that our mouths often suffer from foodfullness at mealtimes. Consuming food can coat choppers with a layer of cuisine-debris, and the nutritional mess must be brushed away before a cavity is formed.

Many of us use water to lubricate the toothpaste-slathered toothbrushes that clean our teeth. This is generally considered a good thing, but there are people in the world who do not turn off the water when they brush. They let the water swirl down the sink like a spiraling torrent of waste.

Clean water is a luxury in some parts of the world. So don't take it for granted. Put a muzzle on your sink's nozzle when you brush. Only activate the tap when you need water. Then turn it right back off. There's no sense in letting clean, fresh water and your hard-earned money go down the actual drain.
