According to your dentist, you should be brushing your teeth at least two times a day. Brushing keeps your teeth, gums, and mouth clean and healthy by removing bacteria causing plaque. It is also recommended that when you brush your teeth, you use a soft bristle toothbrush and toothpaste that contains fluoride. You should spend at least a minute on the top teeth and a minute on the bottom teeth, and remember to brush your tongue; it will help keep your breath smelling fresh!
