Abstract
An electric toothbrush includes bristles, a bristle driving unit, an orientation detection sensor, and an electrode-based contact detection unit for detecting contact with a body. The contact detection unit includes a first detection unit for detecting contact with or proximity to a rear surface side of a brush portion. The electric toothbrush detects orientation information based on an output from the orientation detection sensor, and estimates a brushing area based on at least the orientation information. In the area estimation, in the case where the brushing area determined based on the orientation information is a dentition surface on a right buccal side or a left lingual side or a dentition surface on a left buccal side or a right lingual side, it is determined whether the brushing area corresponds to the buccal side or the lingual side based on an electric signal obtained from the first detection unit.
