Abstract
Abstract A toothbrush for arthritics has an extended hollow body forming a handle for a removable brush which extends axially from the body when the brush is to be used and which is inverted and inserted into the hollow body for storage when not in use. The cross section of the body portion is sufficiently large to prevent contact between the fingers and the palm when the fingers are wrapped around the body portion in gripping relation, so that curling of the fingers is minimized in grasping the brush.
