When was the toothbrush invented?

We've looked at Space Stations and Higgs Bosons and many other topics on DIT.

But have you ever wondered about the origin of the Toothbrush?

Probably not.

But you should.  


Well, it has an interesting history.

For example, a friend of DIT, who is a Dentist, told us that way way way back "chew sticks" were used.

What is a "chew stick"?

Well that and other interesting facts including when the modern day Toothbrush hit the scene are covered in this very short but interesting article.
