MANUAL TOOTHBRUSH FOR GINGIVAL TISSUE STIMULATION

摘要

A preferably non-electric, non-mechanically actuated toothbrush is providedhaving a generally U-shaped appearance with a rotary brush (14, 16) located,during use, on each side of a tooth to be cleaned. The brushes are configuredto rotate about an axis (24, 26) which is parallel to the long axis of thetooth to be cleaned, and essentially perpendicular to the buccal and lingualgum line, of the user. The brushes are preferably held in contact with theteeth and gum tissue by a resilient section of the toothbrush. In thisfashion, a pushing and pulling motion during brushing results in a rotationalmotion of the brushes. An improved method for cleansing teeth, cleaning theopening to the gingival crevice area, and stimulation of the gingival tissueis provided.
