The toothbrush was invented on June 26 in the year 1498. A toothbrush is a tool we use to brush our teeth. Before toothbrushes, people used things like sticks and feathers to clean their teeth. Keeping our teeth clean is important for our health. Some people brush their teeth after every meal. Others brush once or twice a day. How often do you brush your teeth? Do you floss?
