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.

Claims

1. In a toothbrush comprising a handle portion and a head portion at one end thereof, the head portion having a plurality of longitudinally aligned rows of bristles, a plurality of longitudinal rows of massaging elements longitudinally straddling the rows of bristles, the improvement comprising the width of the plurality of rows of bristles approximating twice the height of a tooth whereby the toothbrush is limited to movement in a longitudinal direction only during the cleaning process.

2. The toothbrush of claim 1 wherein each of the straddling rows has a width of 20 to 40 percent of the width of the plurality of bristle rows.

3. The toothbrush of claims 1 or 2 wherein the head portion is longitudinally curved and the bristles and massaging elements are located on the concave side of the curved head.

4. The toothbrush of claims 1 or 2 wherein the head portion is curved in both a longitudinal and transverse direction and the bristles and massaging elements are located on the concave side of the curved head.

5. An improved tooth brush and gum massaging device comprising a handle, a bristle head connected with said handle, a bristle retaining portion on the bristle head, a plurality of relatively stiff bristles attached to said bristle retaining portion, a pair of lateral portions on said bristle head, a plurality of massaging elements formed of rubber or suitable rubber substitute attached to each one of said pair of lateral portions, the bristle retaining portion being arranged between said pair of lateral portions, the improvement comprising a bristle head having an enlarged width sufficient for a simultaneous treatment of both tooth rows wherein:

the width of the bristle retaining portion is substantially twice as great as the tooth height and the overall width and the overall length of the bristle head form a ratio of at least 2;

3 and the width of the bristle retaining portion is 2.5 to 5 times greater than that of each lateral portion.
