Whiten Teeth With Baking Soda: Does It Work?

Published date field

Baking soda is a common household product that has many uses around the home, from eliminating smells to cleaning carpets. Now, baking soda can be found in many toothpastes and teeth-whitening products. Using it to remove stains from teeth is common practice. But does baking soda really whiten teeth? It does an excellent job at removing surface stains, but you should proceed with caution and always consult your dentist to prevent damage to your enamel.

Home Remedies to Whiten Teeth

How can a simple mixture of equal parts baking soda and water whiten teeth? Baking soda, also known as sodium bicarbonate, is composed of a chemical compound that makes it a great mild abrasive. It is this same abrasiveness that effectively removes surface stains from your teeth and makes them appear whiter. However, if your goal is to remove deeper, older stains, then baking soda will not be as effective. You will need to see your dentist or use a product that was specifically created for whitening teeth.


Always consult your dentist if you are considering using this method to help whiten your teeth. You need to be aware of possible side effects: with continual use, you could cause damage to the enamel that coats your teeth. In addition, baking soda doesn't contain fluoride, which helps strengthen teeth and prevent dental cavities, so you will still need to use regular toothpaste. If you have braces that contain orthodontic glue or use a permanent retainer, don't brush with baking soda. It will soften the glue.

Who doesn't want a beautiful, bright smile free of stains? Getting that smile shouldn't be at the expense of the health of your teeth. For safer alternatives, seek teeth whitening services from your dentist. Learn more about tooth whitening through Colgate's Oral Care resources.
