ABSTRACT:
A gum brush has an elongated handle with a stem end, to which is secured a brush head having a bullet shape and provided therearound in symmetrically distributed arrangement several fin-like projections some of which are parallel to the handle and others are perpendicular to the handle, these projections and the brush head being made of a rubberlike material such as cis-1,4-polyisoprene. In use, the brush head and projections are placed in an infant's mouth and moved at random or are chewed by the infant. As a result, the infant's teeth are cleaned, and, at the same time, its gums are firmed and strengthened.
