A tooth brush includes, in addition to bristles, a plurality of magnetic projections on a handle of the tooth brush for massaging gums, thereby preventing and remedying dental disease such as alveolysis, peris dentosis and the like. The magnetic projections are constituted of rod shaped synthetic resin members each having at a tip end thereof a permanent magnet member or piece. Each of the rod shaped members passes through the handle from a side thereof opposite the bristles and being secured to a common base plate on such side of the handle.
