PROBLEM TO BE SOLVED: To easily remove the dirt of teeth and reduce the abrasion of teeth caused by a toothbrush by mounting a wiping-off member such as sponge on a toothbrush. SOLUTION: A wipe-off brush is provided with a material which is soft and quickly recovers its shape against the compression, such as sponge 3, urethane and the like. The plaque and dirt on grooves and irregular parts of teeth are scraped off by a tip of the tooth brush, and simultaneously wiped off by the sponge 3 and the like. That is, the surface and grooves are simultaneously cleaned, a brushing time can be shortened, and the abrasion of teeth can be reduced. Whereby the abrasion of teeth caused by the brush can be remarkably reduced, and further the slime of teeth can be simultaneously removed, which prevents the foul breath.
