Using baking soda alone with plain water is also quite effective in whitening your teeth and removing the plaque build-up.
How to whiten teeth with baking soda and water. All You Will Need:
1 teaspoon of baking soda
1-2 teaspoons of plain water
Mix half a tsp of baking soda with half a tsp of water in a small cup into a fine paste. Put your toothbrush into the cup, and start brushing your teeth for about 1-2 minutes.
Brush your teeth only up and down and no on the sideways. Remember that the taste of baking soda is not pleasant. Then, wash your mouth with water, as well as the toothbrush.
Repeat this process every second day for one or two weeks and you will notice a small difference in the whiteness of your teeth. After a couple of weeks, continue doing this just once or twice a week.
Caution
Be aware that the baking soda is a mild abrasive, so you should not be brushing your teeth any longer, otherwise it may begin to erode the enamel on your teeth.
Also, remember that brushing your teeth with baking soda should not replace brushing your teeth with a toothpaste every day.
