Abstract
Abstract A combined tooth brush and gum massaging device comprising a bristle head which includes an intermediate bristle portion and at both sides adjoining massaging portions, whereby the width of the bristle head is enlarged up to a value that the bristle portion can overlap teeth of the upper tooth row and teeth of the lower tooth row simultaneously when both tooth rows are in contact with one another. Therefore both tooth rows and adjoining gums can be treated simultaneously.
