Abstract

An improved toothbrush with a secure grip, a more effective bristle arrangement, and a specially shaped head is disclosed. The handle is formed with opposed gripping portions, and fits securely in the hand of the brusher, facing either up or down, imparting to the user a very secure and comfortable feeling. The toothbrush has a narrow and thin head for maximum access to the oral cavity, and a novel bristle arrangement which is highly effective for the removal of plaque from teeth with manual brushing. In one embodiment, the brush head is tapered to a narrow portion, and then optionally flares out again. In another embodiment, the head is formed with a wavy profile. In yet other embodiments, the brush head may also be provided with an upwardly curved or an angled tip. The head may also have a rubberized lower portion to effectuate gum massage, a gum stimulator, and a head with visibly different utilization areas.
