Sodium bicarbonate, commonly known as baking soda, is a widely used household product. Not only can it be used for baking, but it also has a variety of cleaning and deodorizing uses. But what about whitening teeth?

While some people may swear by the use of baking soda for whitening teeth, there is no scientific evidence to support this claim. In fact, abrasive materials like baking soda can actually damage your tooth enamel and lead to more staining over time.

There are some toothpastes on the market that contain baking soda, and while they may help remove surface stains, they are no more effective at whitening teeth than regular toothpaste. If you’re looking for a safe and effective way to achieve brighter teeth, talk to your dentist about professional whitening treatments.

What is Baking Soda?

Baking soda is a white, powdery, alkaline substance. It has a slightly salty, soapy taste. People have used baking soda as a home remedy for centuries. It’s a natural cleansing and whitening agent.

How Does Baking Soda Work?
The reason baking soda works so well as a whitening agent is because it’s mildly abrasive. This means it can remove surface stains from your teeth without harming the enamel.

Baking soda is also a natural pH neutralizer, which means it can help to balance the acidity in your mouth and protect your teeth from cavities.

Is Baking Soda Safe for Teeth?
Yes, baking soda is safe for most people to use on their teeth. However, it’s important to be careful not to overuse it, as it can damage the enamel on your teeth if used too often or in too high of concentrations.

If you do decide to use baking soda to whiten your teeth, be sure to do so no more than once or twice per week, and always follow up with a good fluoride toothpaste to help protect your teeth from cavities.

How Does Baking Soda Work to Whiten Teeth?

Baking soda is a mild abrasive, which means it can help remove surface stains from teeth. It’s also alkaline, so it can help reduce the acidity of your mouth, which can lead to less staining.

To use baking soda to whiten your teeth, mix it with water or toothpaste to form a paste, then brush your teeth with it. You can do this once or twice a day. Be sure to spit it out after brushing, as you don’t want to swallow baking soda.

If you have sensitive teeth, use less baking soda or mix it with more water. You should also be sure to rinse your mouth well after using it.

Baking soda isn’t the only whitening agent you can use at home — you can also try hydrogen peroxide or lemon juice. But be careful — these agents can be corrosive, so be sure to use them sparingly and diluted with water.

Does Baking Soda Have Any Side Effects?

Baking soda is generally considered safe for most people. However, there are some potential side effects to be aware of. These include:

-Damage to tooth enamel: Baking soda is abrasive and can damage the enamel on your teeth. If you use it too often, it can wear down the enamel and make your teeth more susceptible to cavities.
-Irritation to gums: Baking soda can also irritate your gums. If you have sensitive gums, be sure to brush gently and avoid using baking soda too often.
-Stomach upset: In large amounts, baking soda can cause stomach upset and gas. It’s best to use it in small amounts and drink plenty of water when you do.

If you’re planning on using baking soda to whiten your teeth, be sure to talk to your dentist first. They can help you find the best way to whiten your teeth without damaging them.

How to Use Baking Soda to Whiten Teeth

There are a number of ways to use baking soda to whiten teeth. You can mix it with water and swish it around your mouth for a minute or two before brushing your teeth as normal. You can also add a little baking soda to your toothbrush before brushing. Some people prefer to make a paste with baking soda and water and use that to brush their teeth.

Baking soda is a mildly abrasive substance, so it can help remove stains from teeth. It will not, however, change the actual color of your teeth. If you have severely stained teeth, you may want to consult a dentist for more effective whitening treatments.


So, can baking soda really whiten teeth? The short answer is yes, but it’s not the most effective method. Baking soda can remove surface stains and make teeth look brighter, but it doesn’t penetrate deep into the tooth enamel to break up darker stains. For best results, use baking soda in combination with other whitening methods, such as bleaching or professional teeth cleaning.
