Eating strawberries can whiten your teeth

Eat More Strawberries. Strawberries contain malic acid, which removes discolorations on the surface of the teeth. Additionally, the berries’ texture helps buff the enamel, creating a brighter, smoother appearance. To heighten the effects of strawberries as a natural teeth whitener, combine a crushed berry with one half of a teaspoon of baking soda. Once the mixture is complete, apply and leave on teeth for five minutes. Only do this once in a while, to keep the enamel of the teeth from breaking down.
