The mouthpiece can be plugged into a variety of devices. Find the appropriate plug and plug into the mouthpiece. Brush your teeth and apply serum to the front of your teeth. The serum may take a few turns to come out the first time. Apply using the brush at the top of each tooth and brushing down towards the bottom of the tooth.
Place the mouthpiece in your mouth and wrap your lips loosely around the device. Use for 9 to 30 minutes. Remove the mouthpiece (you may also spit out excess saliva here), unplug, and rinse with water. You may also use gentle hand soap on the device for extra cleaning. Dry off, replace into the holder, and store.
Use once a day for 21 days, then for touch-ups as needed after - we recommend two times a week at least.
