Your Teeth Are Amazing! 5 Fascinating Facts
They help you chew, speak and smile, but how much do you really know about your teeth? Here are some of the “tooth truths” that prove your teeth really are remarkable.

Around 5,000 B.C., the Egyptians used crushed eggshells and ground animal hooves to clean and polish their teeth.

Modern toothbrushes with nylon bristles arrived in the late 1930s, and the first electric toothbrush was introduced in 1954.
