Question: how to make your teeth whiter with lemon juice?
Answer: If you're going to do tooth whitening at home, you're better off using an over-the-counter product rather than a DIY technique. Pinterest Tip: Mix 3 teaspoons of baking soda with 2 teaspoons of lemon juice. Use a Q-tip or cotton ball and gently swab teeth. After 30 seconds, rinse and brush teeth.
