An electric toothbrushing device is disclosed, the device comprising means for producing vibration of a toothbrush head, means for producing an orientation signal indicating of an area of the mouth being brushed, and means for producing a pressure signal indicating a pressure applied to the toothbrush head. The device further comprises processing means arranged to link values of the orientation signal with values of the pressure signal in order to provide feedback to a user regarding a brushing pressure applied to each of a plurality of different areas of the mouth. By linking values of the orientation signal with values of the pressure signal, the user can be better informed about which parts of the mouth are being or have been brushed too hard. This can help the user to correct their brushing technique.
