Doesn't Maintain Whiteness

Forget about gaining whiteness. I had white teeth to start with. I love love love Tropical Traditions products, but not this one. My teeth looked worse and worse the longer I used it (just a month), and when I went back to my Jason Seafresh (which isn't quite as healthy, granted...) my teeth started brightening right away, and I could tell after the second brushing. I'm still on the hunt for a healthy recipe that doesn't turn/allow my teeth to yellow/gray.
