The angle toothbrush, specifically designed to improve oral hygiene by reaching difficult areas, was popularized by Dr. Philippe P. D. G. Dufresne, a French dentist, in the 1990s. He aimed to create a toothbrush that could effectively clean hard-to-reach areas in the mouth. While various toothbrush designs have existed over the years, Dufresne's innovation focused on the ergonomic angle, enhancing accessibility and effectiveness.
