Oral care implement having tissue cleaning elements with directional cleaning

摘要

An oral care implement or toothbrush 100 includes a head 104, a tooth cleaning element region 116 and a tissue cleaning element region 114. The tissue cleaning element region 114 includes a plurality of flexible, angled projections 120. The projections 120 are configured to flex from an at-rest position to a substantially flat position when the tissue cleaning element region 114 is in contact with the tongue and is pushed into the mouth. The projections 120 are also configured to flex to a substantially upright position when the tissue cleaning element region 114 is in contact with the tongue and is pulled out of the mouth. This arrangement aids in preventing debris from being pushed into the mouth and in removing debris from the mouth and tongue. The flexible projections 120 may be used in conjunction with rigid projections 122 having a generally vertical configuration to aid in removing debris from the mouth and in engaging the cheek to improve saliva production during brushing.
