A new and improved toothbrush (1, 10, 20) has a pair of discreet twin brushi ng heads (5, 6, 14, 15, 24, 25). Each head is attached to the handle portion (2, 11, 21) at a predetermined angle relative to the handle portion. The heads are arranged in a side-by-side manner with the angle of the heads tilted in the opposite direction relative to the handle portion. In one embodi- ment, the heads (5, 6) are fixed relative to the handle portion (2). In another embodiment, the heads (14, l5) are fixed relative to a handle portion (11), but the handle portion flexes when sufficient pressure is applied to the brushing heads during brushing. In still another embodiment, each head (24, 25) pivots independently of the oth er head about a base head (40) which is attached to the handle potion (21). One unique aspect about the twin-headed toothbrush i s that the toothbrush is specifically designed to be used with a conventional brushing technique that the majority of the people are accustomed to, but provide an effective cleaning of teeth and gum surfaces.
