To make sure the whitening gel stays in contact with your teeth all trays we sell come with reservoirs.
Reservoirs provide a tiny space between your teeth and the tray so you do not squeeze the gel out when you place the tray onto your teeth.
Check the competition! You will be back! If you want to whiten your teeth and not your gums you must get a system with gel reservoirs!
