Abstract
An interdental treatment device, such as a toothbrush, includes a handle configured to accommodate an electric power source, a head carrying an interdental treatment tool, and a neck between the handle and the head. The head or neck includes a mechanical motorized vibratory device, including a drive which causes the head to vibrate. Electrical connections are operably connected to the mechanical vibratory device and the electric power source to power the mechanical vibratory device via the electrical connections. At least parts of the electrical connections are formed by tracks of an electrically conductive plastic material. In various embodiments, a vibration-damping structure dampens vibration transmission from the head to the handle.
