User: How often should you brush your teeth?
Assistant: Oral Hygiene is important to maintain a healthy mouth free of disease.   Keeping one's mouth clean avoids problems such as bad breath as well as tooth decay, gum disease and gingivitis.  General guidelines for adults suggest brushing at least twice a day with fluoridated toothpaste.   A good strategy is to brush your teeth in the morning and before you go to bed each night.
