Yellow, even though I rarely drink coffee, tried everything to no avail.
I brush everyday since I was a kid, only had about 3 cavities all my life and they were the small half hour appointment type.
Turmeric do whiten my teeth!!! (yes the spice) search for it it really works.
Activated Charcoal did not work for me
All these youtube videos showing magic after first use and I did not see any difference in two weeks... Found an Amazon review of a guy who did not see any results also so it was not me.
