The mouthpiece can plug into a variety of devices. Find the appropriate plug and plug in the mouthpiece. Brush your teeth and apply serum to the front of teeth. It may take a few turns for the serum 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 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 a gentle hand soap on the device for extra cleaning. Dry off, replace into 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.
There are two strengths of serum in the kit, regular and maximum strength. This allows you to customize the level of whitening to your liking.
