Very good stuff! Whitens several shades within 4-5 uses! Wow
I should have taken a before picture but let me tell you, my teeth were discoloring from my coffee habit. During the pandemic and working from home I really did not bother whitening my teeth. I have never had bad teeth but I noticed within the past few weeks that they're not longer white! I am on my 6th strip and my teeth went from coffee stained to a VIVID WHITE. Worked better than I had hoped! I am going to use 2 more strips so I can go from vivid white to LED white lol Purchasing more to always have some on hand.
