Toothbrush is the English word for "牙刷". It is a small brush used to clean the teeth and remove plaque and food debris from the surfaces of the teeth. The bristles of the toothbrush are typically made of nylon or other synthetic fibers, and the handle of the toothbrush is typically made of plastic or rubber. Toothbrushes come in various sizes and shapes, and can be electric or manual. They are an essential tool for maintaining good oral hygiene and keeping your teeth and gums healthy.
