Abstract:
1. An electric toothbrush, comprising: a bristle-vibrating unit configured to vibrate toothbrush bristles to clean a side of teeth in contact with the toothbrush bristles; a bristle direction-sensing unit configured to detect a direction to which the toothbrush bristles are directed in an oral cavity, the direction being one of directions toward a buccal side, a lingual side and an occlusal side, the buccal side being an outer side of the teeth, the lingual side being an inner side of the teeth, and the occlusal side being a chewing side of the teeth; and a control unit configured to automatically control the bristle-vibrating unit in response to the detected direction such that the vibration intensity of the toothbrush bristles when the buccal side or the lingual side is brushed is weaker than the vibration intensity when the occlusal side is brushed.
