Abstract: A disposable toothbrush formed of a biodegradable material such as biodegradable plastic. The toothbrush would fit, preferably, over the index finger of a user. By using the index finger, it is easy to reach any part of the teeth by locating the toothbrush so as to apply a brushing action to the upper and lower teeth, with the toothbrush located on the outside or inside of the index finger. A toothbrush cap provides an opening for receipt of an index finger of a user. On a flattened portion of the toothbrush cap, are defined two to four rows of short bristles, preferably 3/16 inches in height. These bristles may be formed integrally with the toothbrush cap or include bristles imbedded in the cap. These bristles are impregnated with dehydrated toothpaste which bonds with the bristles to form a defined layer on top of the bristles. Upon contact with water, the impregnated toothpaste would hydrolyze to aid in brushing of the teeth for a single use.
