Your dentist (and the American Dental Association, we might add) recommend that you brush your teeth at least two times a day. Brushing is the best way to keep your teeth, gums, and mouth clean and healthy by removing the plaque that causes bacteria. It is also often recommended that you use a soft-bristled toothbrush and toothpaste that contains fluoride when you brush your teeth. You should spend at least two minutes brushing your teeth each time you do (a minute on the top and a minute on the bottom is a good measure!), and remember to brush your tongue too for fresh-smelling breath.
