How to care for you mouth while you have braces. 

The most important factor in keeping your teeth and gums healthy during orthodontic treatment is brushing and flossing. The American Association of Orthodontics recommends that you brush and floss your teeth after every meal and before you go to bed. It is important to keep the teeth clean because food can get caught in the braces and cavities will form. Some orthodontists will prescribe a 4 % fluoride gel to brush with, to strengthen teeth even further and avoid cavities.

I can understand that some older people who weren't young during the popularization of orthodontics want straight teeth, but they really should not opt for those stupid clear braces.  You are not fooling anyone when you where those around, you just look like a goof wearing gross, clear mouth trays.
