The present invention relates to an improved toothbrush assembly in which
oscillating brush head is
used. It is obvious that brushing should be done in an up-and-down direction,
means along the teeth,
not across which is found in conventional electric toothbrushes. The proposed
toothbrush head
overcome existing problems by allowing bristles moving along the teeth
removing plaque very
effectively by sweeping it out of the teeth.
