Abstract
In a toothbrush with a body providing a brush head and a handle and bristles fastened to the brush head, a hygienic, bacteria-avoiding construction is obtained in that the body and bristles are made of the same material and are welded to one another so that the brush head is free of empty space. Further, with this construction a larger number of bristles can be applied to achieve a better cleaning and massaging effect and the dimensions of the brush head can be reduced.
