I searched it, but they're all complicated for me. I'm 13 and it's hard for me to get some of the ingredients for teeth whiteners(my parents will get curious if I ask them to buy the ingredients). Like baking soda and peroxide..I don't even know where to get peroxide. No strawberries at my house. And any whitener with baking soda won't do it for me. There's some in the fridge and freezer, but it seems like it's been there for like years. It might work, but I feel like it might ruin my teeth instead. Please something easy!!
