An alternative way to use this method is by simply dipping a wet toothbrush into the baking soda and using it to brush your teeth.

Baking soda is a mild abrasive agent. Excessive use of it can erode your enamel. All the methods described above should not be used more than once in a day. Whatever method you choose to use, do bear in mind that you should only use the method for no longer than two weeks in a row. Remember to give a one week break and if need be, repeat the method.

Do take your time to brush gently with low brush force and preferably using a soft brush while using the teeth-whitening remedies. Do not scrub your teeth or gums too furiously. If your gum hurts or bleeds after using any of these methods, it is strongly advised that you discontinue its usage immediately, and consult your dentist.


Fluoride is a very important ingredient and is always present in most toothpaste. It is therefore not in your best interest to abandon your normal toothpaste for baking soda. Use baking soda for teeth whitening purposes, and continue to use your regular toothpaste to brush your teeth.

In conclusion, how to whiten your teeth with baking soda is as easy as the methods outlined above. These are homemade remedies on a very low budget that won’t affect your pocket negatively.
