An apparatus for indicating a duration of time for brushing designated teeth and specific portions thereof has a tooth carrying body including an upper tooth carrying structure and a lower tooth carrying structure. The tooth carrying structures are in spaced apart relation with respect to each other in a manner whereby the tooth carrying structure resembles dental gums in a fully or partially open orientation. A first set of tooth-shaped bodies is attached to the upper tooth carrying structure and a second set of the tooth-shaped bodies is attached to the lower tooth carrying structure. Each one of the tooth-shaped bodies includes at least two discretely illuminatable portions. Each one of the discretely illuminatable portions has a respective selectively activatable light output device coupled thereto for allowing each one of the discretely illuminatable portions to be selectively illuminated.
