The brush head should not be too big, usually the length can cover the tooth surfaces of two front teeth, and the width should not exceed four rows of bristles. The hardness of bristles should be moderate. Appropriate bristles should be selected. In fact, relatively sharp bristles are not easy to clean, and relatively hard bristles may damage the hard tissues of teeth and cause dentin hypersensitivity. The brush handle is comfortable to hold, not easy to loosen and slide, and has certain elasticity. Toothbrush brand recommendation
