ABSTRACT:
A disposable toothbrush which includes a tubular housing forming a handle and a telescopically slidable brush head carrier mounted in the housing. The brush head carrier includes a brush head with tapered plastic bristles which have a central cup position therein to receive dentifrice. The brush head is pivoted to the carrier and forms a closure for the end of the tubular housing when in retracted position. A wedge-shaped member on the brush head retains it in optimum brushing position. A retaining projection on the brush head retains the brush head in optimum brushing position and a latch structure retains the carrier in extended relation to the tubular housing. The brush head includes a removable bristle assembly to enable multiple use cycles of the toothbrush.
