A toothbrush is a small tool used for cleaning teeth. It usually has a handle and a head with bristles that help remove food particles and plaque from the surface of the teeth. Regular brushing with a toothbrush is important for maintaining good oral hygiene and preventing cavities. Many people use toothpaste, which often contains fluoride, to enhance the cleaning process. Toothbrushes come in various types, including manual and electric versions. Electric toothbrushes can make brushing easier and more effective, as they often have built-in timers and different cleaning modes. Choosing the right toothbrush and using it properly can lead to a healthier smile and better overall dental health.
