HISTORY OF THE TOOTHBRUSH



Though original toothbrushes started out as chewing sticks, over the years the toothbrush has changed quite a bit.



3500 B.C. Babylonians & Egyptians

Bristles

Ranges from very soft to hard in texture



Handles

Straight, angled, curved



End-tufted brush

Shaped in pointed arrow pattern to allow closer adaptation to gums. Used for cleaning along gum line adjacent to teeth



Chewable toothbrush

Miniature plastic moulded toothbrush, used when no water is available



Interdental brush

The fundamentals have not changed since the Egyptians and Babylonians -- a handle to grip and a bristle with which to clean the teeth. Over this long history, the toothbrush has developed to become a scientifically designed tool using modern ergonomic designs and hygienic materials to save us from cavities and disease.
