Abstract: A dental floss dispenser with floss reminder adapted to hold spools containing threads of the dental floss. Four embodiments of the dispenser are disclosed. Three of the embodiments are mountable on a bathroom wall. Each has a toothbrush rack with projecting pairs of rectangular toothbrush supporting members. In two of the wall mountable embodiments, one of each pair of the toothbrush supporting members houses a semiconductor chip product that has a switch which is activated when a toothbrush is inserted or extracted. The semiconductor chip product emits an auditory sound when activated to remind the user to floss. One embodiment emits a light signal. A caddy holds a conventional floss dispenser. In the third wall mountable embodiment, an electrical circuitry including a signal generator is used instead of the semiconductor chip product. A fourth embodiment is structured as a cup with a cover.
