A new and improved toothbrush has a pair of discreet twin brushing heads. The heads are arranged side-by-side with independent head flexure. The heads are attached to the handle through use of two discrete neck segments that have purposeful flexure. Each head is connected to one neck segment, thereby permitting independent head flexure. The heads may be angled relative to each other so as to provide two discrete stabilizing contact areas, these contact areas being the respective "high" areas of the two brushing heads that initially meet the teeth and gum surfaces.
