Abstract
Abstract A device for massaging gums having a handle portion arranged for manually manipulating the device in order to impart a swivel-like movement to a gum massaging element that is mounted on the handle portion and configured for insertion between adjacent teeth of a user of the device. A universal joint coupling structure interconnects the handle and the massaging element to allow a free changing of the angular relationship therebetween to provide the swivel-like movement of the gum massaging element.
