The present invention is concerned with a mouth cleaning device comprising a head portion (1) comprising cleaning elements (6) for cleaning teeth and a tongue cleaning electrode (4, 9, 15, 22) enabling a current flow into a users tongue in a use state, wherein the cleaning elements (6) and the tongue cleaning electrode (4, 9, 15, 22) are essentially arranged on opposing sides of the head portion, a handle portion (21) comprising a contact electrode (35), wherein the contact electrode (35) of the handle portion (21) enables a current flow into a users hand in a use state, and an energy source, wherein the energy source is electrically coupled to the contact electrode (35) and to the tongue cleaning electrode (4, 9, 15, 22) such that in operation a current may flow from the contact electrode (35) through a users body to the tongue cleaning electrode (4, 9, 15, 22). The invention is also concerned with a respective head portion. The proposed mouth cleaning device provides for an improved cleaning of the oral cavity as it also provides for specific tongue cleaning capabilities.口腔清掃装置のヘッド部分を開示する。ヘッド部分は、電気的接続要素と、歯を清掃するための清掃要素と、使用時に使用者の舌内に電流を流すための舌清掃電極と、を含む。清掃要素と舌清掃電極とは、ヘッド部分のほぼ反対の側面上に配置される。ヘッド部分の電気的接続要素は、接続状態においてハンドル部分に配置された対応する電気的接続要素と電気的接続を確立するために、舌清掃電極に電気的に接続される。
