Abstract: A reuseable toothbrush cap assembly which defines a first compartment dimensioned and arranged to substantially enclose and protect the bristle portion of a toothbrush while allowing the graspable handle portion of the toothbrush to extend outside the compartment such that the toothbrush may continue to be stored in a conventional toothbrush holder. The toothbrush cap assembly further defines a second compartment dimensioned and arranged to receive a spool of dental floss, and a cutter dimensioned and arranged proximate an opening in the second compartment through which dental floss may be withdrawn to thereby allow cutting of the same into a segment of desired length.
