How to Floss with Orthodontics :
When flossing, insert the floss behind the archwire with the aid of a floss threader. Gently clean the sides of your teeth and under gums with an up-and-down motion. Floss between all teeth at least once a day, usually before bedtime.
A water pick can be very helpful, but it is to be used after thorough brushing. It is not a substitute for brushing, but does remove food particles that the brush cannot reach. Be careful not to turn it on a high setting since it may damage your gums.
