i am not sure what causes the discoloration. but -
i do not drink tea or coffee. i only drink water and sometimes lemon with hot water and honey drink. oh yes- coccnut juice too. hmmm- coconut juice make stains?
and then a smoothie once every two weeks- maybe that often!? blueberries with bananas and rice milk but that is it. even then i rinse my mouth out afterwards.
