I’m 62 and a former smoker. Nothing seems to work on older teeth when they are yellowing or graying I found this product to work very well. I like how the mouthpiece works and I also like how their white strips work and self dissolve. My teeth will never be white white but it does keep them from being noticeably discolored. I also had a mouthpiece that stopped working after a period of time, and when I inquired about getting a new one, I was sent one at no cost and very quickly. The lip balm as a gift is amazing too.
