The toothbrush has excellent suitability for bristle insertion into narrow parts, e.g., the gaps between neighboring teeth and gaps between the teeth and the gums. It is highly effective in removing dental plaque and cleaning the teeth. It is highly easy to use in the oral cavity. It further has a highly attractive appearance.
