#3. Make a lemon juice and baking soda paste
Baking soda is mildly abrasive, which means that it’s really good at removing any surface stains on your teeth, thereby returning them to their original white shade. It’s also alkaline, which means that it helps to balance out your mouths Ph levels. All you need to do is mix together a few teaspoons of baking soda with lemon juice in order to make your paste. Then, dab some of the paste onto your toothbrush before giving your teeth a good scrubbing.
