Please help! does bi-carb soda and lemon juice whiten your teeth?
A doctor has provided 1 answer
No, not really: Lemon juice is acidic, which can slowly dissolve your enamel. Baking soda is abrasive, so it will remove superficial stains making your teeth look whiter (since there are no stains) but it will not actually lighten the color of your teeth.
