10. Activated charcoal
Activated charcoal is one of the easiest and most inexpensive ways to naturally whiten your teeth. Crush up one charcoal tablet into a powder. Dip your clean wet toothbrush into it, and brush your teeth as you normally do.
9. Powdered milk and toothpaste
Powdered milk will help to make your teeth pearly white and keep them healthy. Put some toothpaste on your toothbrush, add a bit of powdered milk on top of it, and brush your teeth.
8. Baking soda and lemon juice
Put a pinch of baking soda on your toothbrush, and add a few drops of lemon juice over it to get a set of shining teeth. Remember not to use this whitening method more frequently than once a week.
7. Hydrogen peroxide
Before using hydrogen peroxide, make sure that your teeth aren’t too sensitive. If everything is fine, simply dip a cotton swab into the peroxide, and gently rub your teeth. However, this whitening technique isn’t recommended for frequent use as it can harm your enamel.
6. Baking powder and lemon juice
A teaspoon of baking powder and a teaspoon of freshly squeezed lemon juice will work wonders in just 2 minutes. Don’t keep this mixture on your teeth for more than 2 minutes.
