Claims28
A toothbrush comprising:
- a handle;
- and
- a head extending from a proximal end to a distal end along a longitudinal axis, the head including a base portion and a flexible portion, an open area formed between the base portion and the flexible portion, the open area forming a transverse passageway through the head from a first side of the head to a second side of the head, said flexible portion being readily deflectable from an original orientation during use of said toothbrush and configured to recover to the original orientation after use of said toothbrush;
- wherein the flexible portion of the head is coupled to the base portion of the head only at the proximal and distal ends so that the flexible portion is spaced apart from the base portion at the first and second sides of the head;
- wherein the flexible portion of the head has an upper surface and an opposing lower surface, cleaning elements extending from the upper surface, and wherein the upper surface of the flexible portion is substantially planar.

A toothbrush comprising:
- a handle;
- and
- a head extending from a proximal end to a distal end along a longitudinal axis, the head including a base portion and a flexible portion that are coupled together at the proximal and distal ends of the head, the base portion and the flexible portion being spaced apart from one another between the proximal and distal ends of the head thereby forming an open area between the base portion and the flexible portion, the open area forming a passageway through the head from a first opening in a first side of the head to a second opening in a second side of the head;
- wherein the flexible portion of the head is coupled to the base portion of the head only at the proximal and distal ends so that the flexible portion is spaced apart from the base portion at the first and second sides of the head;
- wherein the flexible portion of the head has an upper surface and an opposing lower surface, cleaning elements extending from the upper surface, and wherein the upper surface of the flexible portion is substantially planar.
