toothbrush

A toothbrush is a handheld tool used to clean teeth and gums. It typically has a handle and a head with bristles that scrub away plaque, food particles, and bacteria. Regular brushing with a toothbrush helps prevent cavities, gum disease, and bad breath. Modern toothbrushes can be manual or electric, with electric models providing automated brushing motions. Proper toothbrush use combined with toothpaste enhances oral hygiene. Replacing the toothbrush every three to four months or sooner if the bristles fray ensures effective cleaning and maintains oral health.
