BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toothbrush head and a toothbrush including the toothbrush, and more particularly, to a toothbrush head and a toothbrush including the toothbrush that can specifically clean the teeth and can flexibly clean teeth.

In general, effective plaque removal and gum disease prevention are necessary to maintain healthy teeth. A plaque is a sticky, transparent film that sticks to the surface of a tooth and is also called a plaque. Plaques are made up of many germs (bacteria) living in the mouth clinging to certain components in saliva, and also in teeth, prostheses, orthodontic appliances, dentures and their surroundings. Germs in the plaque not only damage the gums by creating toxins and free oxygen, but they also damage the teeth and surrounding tissues. When the teeth and gums are damaged, they become swollen, bloody, and bad breath. In particular, plaque accumulation in the periodontal pouch caused by the gap between the teeth and gums damages the bone supporting the tooth, and in the worst case, the tooth is lost.

To effectively remove such plaque, the bristles must reach all areas including the tooth surface (the surface of the tooth, the surface of the tooth), the tooth (between the neck and the tooth and the gum), and between the tooth (between the tooth and the tooth). It is important to ensure that the bristles reach all areas, such as between the tooth and the teeth (interdental), and that the bristles reach the back of the molars, especially in the deep part of the mouth, so that the brushing is done evenly. In addition, it is important to prevent gum disease by brushing the teeth with proper gum massage, or by reducing the excessive force applied to the teeth or gums to prevent damage to the gums.

However, since the teeth are arranged in a curved shape, most of the toothbrushes are made of a hard plastic material, so that the toothbrush head is not flexibly bent according to the shape of the tooth, so that the gum is subjected to excessive force do. In addition, the user may exert excessive force on the bristles to reach the teeth located deep in the mouth, and the gums may be damaged due to such excessive force.

To solve such a problem, a toothbrush having a protruding front portion of the bristles has been developed. The bristles can reach the deep portion of the mouth, but the protruded bristles are easily worn. To solve this problem, a brush bristle bristle structure of a toothbrush having a triangular bristle bundle and a rhombic bristle bundle has been proposed (Korean Utility Model Registration No. 20-0306545 (public announcement: Feb. 25, 2003)). However, And it is not suitable for universal use.
