Oral care device

An oral care device comprising:

• a mouthpiece portion for at least partial receipt in the mouth of a user,
• wherein a body of the mouthpiece portion describes an arcuate contour, for approximately following at least a part of a contour of a user's dental arch, and
• wherein the mouthpiece portion carries a set of oral cleaning elements for mechanical engagement with teeth during operation;
• a second portion, coupled to the mouthpiece portion;
• an actuation mechanism for actuating motion of the cleaning elements relative to said second portion, and relative to teeth when the mouthpiece portion is received in the mouth;
• an anchoring member engageable by a part of the user's mouth when the mouthpiece portion is received in the mouth for normal use, for holding the anchoring member fixed in position with respect to the jaws, wherein the anchoring member is not attached to the mouthpiece portion and wherein the anchoring member is configured to move relative to the mouthpiece portion;
• wherein the anchoring member is mechanically coupled to said second portion via an anchoring member coupling,
• wherein the anchoring member coupling is such as to permit relative motion between the anchoring member and the mouthpiece portion in at least a first direction, the first direction being transverse to a direction of motion of the cleaning elements, and
• wherein the anchoring member coupling is such as to at least partially prevent relative motion between the anchoring member and the mouthpiece portion in a second direction, the second direction being substantially parallel with said direction of motion of the cleaning elements.
