For stimulating acupuncture points in the oral cavity, a toothbrush has, on the brush head (1), a negative end magnetic pole (5), lateral magnetic poles (6a,b) of opposite polarities and upper magnetic poles (7a-c) which have alternately opposite polarities, that of the foremost magnetic pole (7a) differing from that of the end magnetic pole (5). The field strength at the surface of the toothbrush is between 600 and 1500 Gauss in the vicinity of a magnetic pole. The magnetic poles (5, 6a,b, 7a-c) are produced by magnetic plates (4a-f) integrally cast close to the surface. Instead of being let directly into the brush head, the magnetic plates can also be let into an attachment which can be pushed onto a conventional toothbrush. Toothbrush or attachment may also have certain colours for achieving an additional chromotherapeutic effect.
