Hydrogen peroxide with baking soda for teeth

If your smile isn't as bright as it should be, you may wonder how to whiten your teeth with baking soda or peroxide. Let's examine the process and limitations of baking soda teeth whitening. 

How can I whiten my teeth with baking soda at home?

The process of using baking soda to whiten teeth is rather simple. You simply make a paste out of a teaspoon of baking soda and a small amount of hydrogen peroxide, and then gently brush your teeth as you would with traditional toothpaste. When you are done, rinse your mouth with water.

It's best to use a soft-bristled toothbrush with this method, as baking soda is abrasive and can damage tooth enamel if used incorrectly. According to Healthline, it's that abrasiveness that can whiten your teeth. They explain "Baking soda is a mild abrasive. While the American Dental Association (ADA) considers baking soda safe for your enamel and dentin, some researchers have given it a low rating as a teeth whitener because it may not remove stains as effectively as some other products."

Not only does it not remove all stains, but baking soda can cause damage to your enamel that may cause bigger problems in the future. CNN says:

"Baking soda could erode the tooth's surface enamel over time. Enamel is like the finished surface of a floor: It's a thin, hard outer layer that protects each tooth. When enamel is worn away by an irritant, such as salt, decay can occur as bacteria in plaque are able to penetrate teeth more quickly, where they produce acids that can lead to cavities."

What can I use instead of baking soda to whiten my teeth?

It is generally recommended to use toothpaste that is approved by the American Dental Association. If you desire more whitening than regular toothpaste can offer, you may consider an ADA-approved whitening toothpaste. That way you can be confident that it is good for your oral health, and likely better for your teeth than a home remedy.

If you have more severe tooth discoloration, you may want to investigate other ADA-approved teeth whitening products or discuss whitening treatment with your dentist.

Very little can compare to professional tooth whitening when it comes to results.

At Smiles of Cary, our teeth whitening process starts with the application of protective gel over gums. Next, we apply whitening agents that commonly contain hydrogen peroxide or carbamide peroxide. These peroxides enter the porous enamel layer and undergo oxidation that clears the stains on your teeth. The whitening gel is applied over the tooth surface and a bright light is shined over the teeth to accelerate the oxidation process.

In just about an hour, your teeth will be whiter and your smile brighter.
