Retractably Clean Toothbrush, with retractable, disposable bristles and audio/visual reminder system

Abstract

This new toothbrush will have a detachable head of bristles and a storage area for new bristles, so that with just the push of a button, the old, dirty bristles drop off, and a new head of bristles slide out. It will also have a built in reminder that flashes red when it's time to replace it. An LED light (and/or a speaker with a voice recorded on a small computer chip for the more upscale consumer), along with a simple timer device, will remind people that it is time to replace the old bristles with a new set. The new bristle heads will be kept in a storage area in the handle, and additional heads can be in a separate container, much like the blades of a disposable razor. When the handle and container are empty, a refill of new bristles can be purchased at a price for everyday consumers as well as our more elite buyers. In order to shield the bristles that are in use against contamination from other sources when the toothbrush is not in use, the bristle head can be retracted back into the handle's storage area.
