Baking soda is also known as sodium bicarbonate. It is a fine, white powder with many household uses. The substance is primarily used as a leavening agent.
Sodium bicarbonate is also commonly used to whiten teeth and fix tooth discoloration.
Yes, baking soda is good for your teeth. While it cannot protect your teeth from cavities the same way fluoride toothpaste can, it is still considered an excellent cleaning agent for your teeth.
Baking soda toothpaste has antibacterial properties. This helps protect your teeth from tooth decay.1
To whiten your teeth with baking soda, you will need the following:
Here is how to whiten teeth with baking soda:
Some people suggest adding lemon juice or apple cider vinegar to the baking soda mix to boost the whitening power of the solution.
However, this may not be a good idea as the citric acid of the lemon juice and apple cider vinegar may affect the surface of the teeth and leave you vulnerable to cavities.
You can expect results after a couple of weeks of regular brushing with baking soda. However, using baking soda to whiten teeth is an abrasive process and should not be used regularly.
Once you notice some results, reduce your brushing with baking soda to once or twice a week to lessen the potential damage to your teeth.
Baking soda and hydrogen peroxide work well together as a teeth whitener.
Here is how to make a hydrogen peroxide paste:
Here are some benefits of using baking soda and hydrogen peroxide as a teeth whitener:
Biofilms are colonies of bacteria that stick to the surface of your teeth and lead to problems like gingivitis and cavities. Dental plaque is one example of a biofilm.
When you brush your teeth with baking soda, its grains disrupt that biofilm, lessening the bacteria count and helping to stop damage to your teeth and gums.3
Some harmful bacteria require more acidic conditions to thrive in your mouth.
A 2017 study proved that when you rinse your mouth with baking soda, the pH in your mouth increases, reducing the acidity.4
Using baking soda as toothpaste may make it more difficult for cavity-causing bacteria to multiply in your mouth.4
Baking soda is a natural bleaching agent with whitening properties. It is effective at removing stains on your teeth and giving you a brighter smile. That is why baking soda is a popular ingredient in many commercial toothpastes.
Studies have proven that baking soda is a mild abrasive that can remove stains from the outside of your teeth.5
Excess fluoride can be toxic, especially to young children under six years old. However, it is essential to note that fluoride toxicity is rare. The risks are only an issue when a significant amount of fluoride is consumed.
Fluoride toxicity can lead to pain, vomiting, diarrhea, and heart and kidney issues. That is why many people prefer toothpaste with baking soda that is free of fluoride and the risks of toxicity.6
Baking soda is affordable and accessible in nearly every drugstore, grocery store, and large retailer.
Here are some risks and disadvantages of using baking soda and hydrogen peroxide for teeth whitening:
The main downside of using baking soda is that it does not taste very pleasant for many people. Baking soda’s texture may make it feel like you have sand in your mouth.
If you want to experience the benefits of baking soda with a better texture, you can try a commercial toothpaste that includes baking soda as an ingredient.
If the texture of baking soda does not bother you, but the salty taste does, you could mix one or two drops of peppermint oil to the baking soda to improve the taste.
Baking soda is a mild abrasive. The American Dental Association (ADA) recommends baking soda as safe for your enamel and dentin. But some researchers give it a low rating as a teeth whitening as it may not remove stains as well as some other products.
Toothpastes approved by the ADA have fluoride to prevent dental cavities. While fluoride is a natural element abundant in water, air, and our bones and teeth, extra fluoride in toothpaste gives an additional shield against tooth decay.
Using baking soda as your toothpaste does not provide you with the topical fluoride present in many commercial toothpastes. Using baking soda may not offer you the cavity protection you need.
Baking soda is recognized as an acceptable product to use on teeth. It is an ingredient in many toothpastes with the American Dental Association (ADA) seal of acceptance. However, it must be used with care.
Remember, sodium bicarbonate does not contain fluoride which helps fight against tooth decay and the strengthening and remineralization of tooth enamel.
With the right concentration, baking soda is not abrasive. It contains the same hardness as dentin and will not wear away your tooth structure considerably unless you are vigorously brushing your teeth. Always make sure you follow the instructions for brushing with baking soda properly and use the right concentrations.
The pH in baking soda will neutralize plaque acids in your mouth by heightening your mouth’s pH balance.
Products containing hydrogen peroxide can whiten your teeth by oxidizing yellow and brown stains on the surface of your teeth.2 The most effective peroxide products are used in dentist offices.
With potent formulas, certain steps must be taken to protect your tongue and gums from the potentially corrosive effects of hydrogen peroxide.
Gentler products can be purchased over the counter, but it may take some more time before you notice a difference.
Natural remedies including coconut oil, lemon peel, and activated charcoal may also be effective teeth whiteners. Be sure to consult with your dentist first to ensure any of these treatments are safe for your teeth.
