Abstract

Conventional toothbrushes must be destroyed and incinerated as refuse after use, resulting in a waste of resources and generating carbon dioxide. A toothbrush is provided separately with: a cylindrical toothbrush portion for attaching a replaceable toothbrush portion, said cylindrical portion provided with an uneven portion to prevent the end portion of the toothbrush swinging in a left to right direction when the cylindrical portion is provided fitted to the end portion of the toothbrush handle; and the replaceable toothbrush portion. Thus, after an appropriate period of use, the replaceable toothbrush can be easily exchanged. The purpose of the invention is to provide a toothbrush which has a toothbrush handle for repeated reuse, and which enables a significant contribution to the reduction of carbon dioxide by a reduction in refuse.
