My friend said that if you rub strawberries on your teeth and wait 20 minutes then brush your teeth it makes your teeth whiter.... Is this true??????

well ur friend is a weirdo

Combined with baking soda, strawberries become a natural tooth-cleanser.
You need:
1 ripe strawberry
1/2 teaspoon baking soda

Directions: Crush the strawberry to a pulp, then mix with the baking powder until blended. Use a soft toothbrush to spread the mixture onto your teeth. Leave on for 5 minutes, then brush thoroughly with toothpaste to remove the berry–baking .

what the heck

why dont you try it yourself? (: its not like your teeth are gonna turn yellow all of a sudden
