PolaNight is applied to a mouth guard or retainer before being worn over teeth:

• Brush and floss your teeth
• In a counterclockwise motion, twist off the clear plastic cap from syringe
• Place a small amount of gel in each tooth compartment of the tray before applying the retainer to your teeth. Remove any excess gel on gums with your finger or a dry toothbrush.
• Wear 2-4 hours once daily or overnight.

Once the desired shade has been reached, continue to apply PolaNight once every two weeks to maintain your white teeth.
