    • 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.
    • 口腔护理器具或牙刷(100)包括头部(104),牙齿清洁元件区域(116)和组织清洁元件区域(114)。 组织清洁元件区域(114)包括多个柔性的成角度的突起(120)。 突起(120)构造成当组织清洁元件区域(114)与舌接触并被推入口中时,从静止位置弯曲到基本平坦的位置。 突起(120)还构造成当组织清洁元件区域(114)与舌头接触并且被拉出口时,弯曲到基本直立的位置。 这种布置有助于防止碎片被推入口中并从嘴和舌上清除碎屑。 柔性突起(120)可以与具有大致竖直构造的刚性突起(122)一起使用,以有助于从口中去除碎屑并且接合面颊以改善刷牙期间的唾液产生。
