A toothbrush doesn't float on water primarily due to its density. The materials used in a toothbrush, such as plastic and nylon bristles, are denser than water, causing it to sink. Additionally, the shape and design of a toothbrush don't provide enough buoyancy to counteract the force of gravity. As a result, it submerges rather than floating.
This depends on the density: if the density is greater than 1 g/cm3 (density of water) an object sink; if the density is lower the object float.I tested just now four tooth brushes: three sink, one float !
Teeth typically do not float in water. Their density is higher than water, causing them to sink. However, in some cases, if a tooth is trapped in food or debris that floats, the tooth may appear to float.
sometimes it does some times it doesnt
wow that's sad a boat that can float is any tye of boat that doesnt have a hole in it
I use warm water and an 1/8 of a teaspoon of salt with a soft kids tooth brush. :-)
soap & water, and a tooth brush to get behind the ears
ok when he is just going asleep, take a plastic cup with cold water and his tooth brush in it. Stick the cup in the freezer. in the mourning, wake up early, take the frozen tooth-brush and put it into the tooth brush holder. and wa-lla he brushes his teeth with a frozen toothbrush
air oxygen food nuts water tooth brush Etc.
You take a sponge and tooth pick and put them togather
no it doesnt because it has lots of mass which makes in sink.
It depends on the size of your mouth and how much tooth paste you use
I have just recently done a tooth exposure for one of my canine teeth. The pain has gone down ..but im still worried on how to brush my teeth. If I brush my teeth with the stitches become loose and then there could be loosening of the stitching in my upper mouth ? How am I suppose to brush ? Do I avoid all contact with that area? Do I avoid tooth paste and rinse with a salt and water solution ? Thnks
