There are two categories of AWS: flexible work schedules (FWS) and compressed work schedules (CWS). FWS consist of workdays with (1) core hours and (2) flexible hours. Core hours are the designated period of the day when all employees must be at work.
Brush down from the top and then up from the bottom on each tooth with braces. Next, brush your teeth with a proxabrush or Christmas tree brush. This brush is specially designed for cleaning between two braces. Insert the brush down from the top and then up from the bottom between two braces. Use several strokes in each direction before moving on to the next space between two braces.
If your teeth were really clean and white when the braces were put on and you did not maintain the same brushing technique whilst the braces were on then when they are removed you will have white and yellow spots on your teeth. Just brush nice and hard and try to remove those stains.
