ABSTRACT:
A toothbrush having a handle formed of a thermoplastic material with a glass transition temperature in the range of about 110.degree.-140.degree. F. The handle is heated to soften the plastic shaped to a desired configuration while pliable, then allowed to cool so as to retain the desired configuration when it hardens. The brush bristles may be detached from the handle when worn and replaced by a fresh set.
