ABSTRACT:
A toothbrush, comprising a handle, having a head portion and a grip portion. The head portion has a plurality of bristle cavities, each for receiving a bristle group. The bristle cavities are connected with passage ways. The bristle groups are mounted in the bristle cavities with a rubber base, creating a seal with its associated bristle cavity, creating a closed system where the bristle cavities are in fluid communication with each other through the passage ways. The closed system is filled with a substantially non-compressible medium. When pressure is exerted on one bristle group, pressure is thereby exerted on the medium, which exerts pressure on the other bristle groups, in turn applying even pressure to all bristle groups. A plaque remover, having a fiberglass pick, is mounted in the grip portion of the handle.
