A toothbrush for use on humans and pets, comprising a toothbrush head with each end curved upward at 90 degree angles; said toothbrush head further comprising four sets of soft bristles. Three sets of bristles are attached to the front face of the brush head, with two sets positioned opposite each other on each upward curved end of the head and the third set of bristles positioned in the center, perpendicular to the other two sets, thereby providing coverage of the mesial, distal and occlusal surfaces of the teeth simultaneously. The fourth set of bristles is attached to the back side of the toothbrush head, thereby cleaning and massaging the opposing teeth at the same time that the other three sets of bristles are doing the primary cleaning. The toothbrush handle is attached to the center of the head for ease of use and the ability to reach the back molars.
