Be sure to rinse/clean your toothbrush at all times and get a new one every 1-3 months - hygiene reasons.

The identity of the person who first invented the toothbrush is not known. Various forms of tooth cleaning have been used for thousands of years.

The Chinese have used the bristle toothbrush since 1498, during the reign of the Hongzhi Emperor (r. 1487--1505) of the Ming Dynasty. The idea is thought to have been brought to Europe by Europeans who had traveled to China.

The earliest identified use of the word "toothbrush" in English was in the autobiography of Anthony Wood, who wrote in 1690 that he had bought a toothbrush from J. Barret.

Mass production of the toothbrush began in 1780 when they were sold by a William Addis of Clerkenwald, England. The modern toothbrush uses nylon fibers instead of pig, boar or badger bristles, and was introduced in 1938 by the DuPont Company.

The cost of replacement heads for the Sonicare toothbrush varies based on the number purchased and the site of purchase. For example, a two pack of replacement heads can be purchased at Target for $24.30.

It would be difficult to imagine a better method of contracting the disease. There are methods that are more fun, though.

Yes. However if you make sure the toothbrush completely air dries between uses the bacterial growth will be limited to safe levels.

that smell will never go away. i used to throw up almost every time i smelled mine. i also have this problem! my orthodontist said that scrubbing it with dish soap and a different brush instead of toothpaste and toothbrush cleans it better. i haven't tried this myself, but maybe it'll help you!

To my knowledge, the input energy would be less than the output due to the fact that no machine is 100% efficient. There would be some energy lost as a result of friction or some other such force that hinders efficiency.

I don't know why the hell you would even stick a toothbrush in your crotch to begin with. That's completely disgusting. But yes, it is normal because usually penis' are longer than a toothbrush. Sometimes the same size. Every male's penis size, length, shape and so on are different. Also, when you are having sex and you are a virgin..the penis has to go in pretty far to pop your cherry. So yes. It is normal to be able to fit a toothbrush in your crotch.

China is credited with the invention of the toothbrush.

It works by killing germs i.e. bacteria, viruses, fungi and protozoa. There are two main types of toothbrush sanitizers for consumers. One type uses UV light to kill germs. The other type, which is more effective, uses steam to kill germs. Given that some germs can make us sick, killing the germs found on the toothbrush therefore sanitizes the toothbrush.
