How often can I use this?Updated a month ago

We recommend completing one full 2-week treatment consecutively, doing one treatment per day. After completing your initial 2-week treatment, it is important to give your teeth some time to rest and rehydrate before completing another treatment. We recommend waiting at least 4 weeks before completing another 2-week treatment. Completing multiple treatments per year will keep your teeth at the bright, white shade that you desire!
