People have been brushing their teeth for thousands of years! In fact, the first "toothbrush" was developed around 3000 BC! Ancient civilizations used the frayed edge of a thin twig to rub against their teeth for cleaning. The first toothbrush with bristles was invented in 1498 in China. Brushes were made out of bone or bamboo and the bristles were formed from the hairs off the back of a hog's neck.
It wasn't until 1938 that the first nylon bristle toothbrush was introduced, and people quickly became aware of practicing good oral hygiene. Here are some other interesting facts:
*The most common toothbrush color is blue
*The first toothpaste was used in China and India in 500 BC
*On average, children smile about 400 times a day
*You should replace your toothbrush every two months
*The first known toothpaste used in the US was in 1780, Colgate was introduced in 1873, and Crest in 1955
