The Original Toothbrush is a one-piece design similar to the Flex Toothbrush but made from cellulose and without a patterned grip on the handle. The Flex (Scuba) Toothbrush is very similar in shape and can be used as a substitute. The Big Brush™ with Replacement Head is an updated version of the Original, featuring a longer neck, less plastic, and more bristles for a fuller, more effective clean.
