The brush has a replaceable application head lying away from a handle of the brush, where the brush vibrates in sound frequency range from 20 to 10,000 hertz. Tip of the application head consists of soft material for accommodating liquids, where the soft material is selected from one of micro fibers, plastic fibers, foam material and felt. A brush tip is attached on the handle. Adhesive is brought into contact with the tooth substance by the tip. The sound frequency is approximately half as large as the vibration of a sound-driven tooth brush. |
