What are these white spots?Updated a month ago

Within the first 1-2 treatments, you may experience small, white spots that form on the surface of your teeth. These white spots are the initial areas of your teeth undergoing the stain-reversing process! Over the course of the full 2-week treatment, the entire surface of your smile will undergo this same change, leading to an evenly balanced, white smile! These spots fade away after a couple of hours during these initial treatments and will not continue to form after 1-2 uses.
