Abstract

An oral care implement with a handle includes a head with a tissue cleanser. The tissue cleanser may be a pad composed of an elastomeric material. The pad is disposed on the head on a surface opposite the tooth cleaning elements. The tissue cleanser may include a plurality of nubs extending for cleaning between the papillae of the tongue. The tissue cleanser may include a plurality of conically shaped nubs. A tissue cleanser can be used to reduce oral malodor problems and remove oral epithelial cells.

Claims (19)

1. An oral care implement comprising:

a head having tooth cleaning elements projecting from a front side of the head, the head having a longitudinal axis;

a cleanser for cleansing soft tissue in the mouth, the cleanser located on a rear side of the head, the cleanser including:

a plurality of elongate base portions fixed to the head, the elongate base portions arranged transversely on the rear side of the head in a spaced-apart manner;

a plurality of spaced-apart projections protruding outward from each of the elongate base portions for removal of microbial and other debris from the soft tissue; and

an elongate longitudinal portion connecting the elongate base portions;

the head being formed at least partially of a first material and the cleanser being formed of a second material which is different than the first material;

wherein the elongate longitudinal portion extends along the longitudinal axis of the head;

wherein each of the elongate base portions comprise a first portion that extends from the longitudinal axis in a first lateral direction, and a second portion that extends from the longitudinal axis in a second lateral direction opposite the first lateral direction; and

wherein the first and second portions of the elongate base portions have a concave shape facing a handle connected to the head.

2. An oral care implement according to claim 1 wherein the base portions and the projections are each comprised of an elastomeric material.

6. An oral care implement according to claim 1 wherein the elongate base portions, the elongate longitudinal portion and the projections are formed as a one-piece member.

7. An oral care implement according to claim 6 wherein the elongate base portions and the projections are each composed of an elastomeric material.

8. An oral care implement according to claim 1 wherein the elongate longitudinal portion of the cleanser extends onto the handle and forms a part of a grip.
