A toothbrush of the present invention comprises a handle and a brush head, the brush head being provided with an outer frame, multiple cylinder bodies, and a flexible filling layer. The outer frame is integrally provided at the tail end of the handle, and the multiple cylinder bodies are provided at intervals to form the shape of a brush head, one ends of the multiple cylinder bodies are recessed to form fixing grooves for implanting bristles, and the flexible filling layer is provided between the outer frame and the multiple cylinder bodies. When the toothbrush of the present invention is used by a user to brush teeth, as the bristles in the multiple cylinder bodies can respectively shift towards different directions, the tooth faces and the tooth gaps can be effectively cleaned, thereby having a good dental cleaning effect and providing convenience for the operation of the user; in addition, the flexible filling layer absorbs an excessive force applied by the user, thereby avoiding damage to the gingivae.
