Does baking soda really work for whitening teeth? I'm cheap and don't wanna buy those stupid strips. I was told baking soda works, has anyone tried it before?
My mom swears by baking soda and lemon juice. I've never done it. I buy the strips and use them as needed.
And her teeth are beautifully white. And her enamel is great too. She's been brushing with it 2-3 times a week since she was 18.
