Abstract

A toothbrush head has a body, multiple cavities, and multiple through holes. The body is an elongated bar and further has a top surface and a bottom surface. The multiple cavities are recessed into the top surface at spaced intervals. Multiple bristle units are respectively mounted in the multiple cavities. The multiple through holes are formed on the body. The multiple through holes are adjacent to the multiple cavities. The multiple through holes are defined through the top surface and the bottom surface directly. The multiple through holes are utilized to remove the moisture and the food residues easily. Furthermore, the multiple through holes may also increase air convection around the toothbrush head. The toothbrush head may be air-dried fast and avoid bacteria breeding effectively.
