toothbrush

Abstract

This toothbrush is used to clean the surfaces of teeth. As shown in the "Reference Diagram Showing How the Product is Used," this product comprises a central brush located in the left-right center and left and right brushes located symmetrically on either side of the central brush, with each brush connected by an elastic body. When the central brush is pressed against the occlusal surface of a tooth, the left and right brushes are pulled toward the left-right center by the elastic body. This allows each brush to contact not only the occlusal surface of the tooth but also both left and right side surfaces and the left and right tooth necks (between the crown and gums), allowing for simultaneous cleaning.
