### Instruction: Why is it important to brush and floss your teeth everyday?
### Response: It is important to use a toothbrush to remove food build-up and plaque that can accumulate on tooth surfaces.  Flossing is important to remove build-up in between teeth in the areas a toothbrush cannot reach.  If plaque is not removed within 24 hours, it can harden into calculus which can only be removed with a professional cleaning.  If plaque and calculus remain on teeth it can increase the risk of gum disease and cavities.  Maintaining a healthy mouth is important for oral health as well as systemic health, e.g. Cardiovascular Health.    Dentists recommend to brush your teeth twice a day for 2 minutes each time and flossing at least once a day.  When brushing it is best to wait 30 minutes after drinking acidic beverages, such as coffee or citrus juice.  Dentists recommend using a soft bristle toothbrush with gentle pressure and using toothpaste with fluoride which can help reduce the risk of cavities by strengthening the enamel.
