Baking Soda Teeth Whitening: The Facts

Baking Soda for Teeth Whitening

First of all, let’s answer the burning question about baking soda teeth whitening, does it work?

Well, the answer is a definite yes, it can in help you to whiten your teeth!

Baking soda or sodium bicarbonate is a white, crystalline chemical compound most often commercially available as a fine powder. It comprises sodium and bicarbonate ions.

Baking soda has a very alkaline taste, and this is actually a clue as to why it can be a great DIY teeth whitening substance.

The alkalinity helps reduce tooth yellowing and discoloration due to food and drink consumption and smoking.

Add this to its mild abrasive action that removes plaque on the tooth’s surface and you have a very versatile natural teeth whitening agent.

Almost everyone wants whiter teeth.

This is evidenced by the fact that teeth whitening has brought in 11 billion US dollars revenue and the annual spend on teeth whitening products is approximately 1.4 billion US dollars. Yes, BILLION! Crazy right?

But not everyone can afford in-office dental tooth whitening procedures because let’s be honest, it’s expensive.

Professional whitening costs an average of $600.

So, it’s no surprise that many people are opting for ways to whiten teeth at-home instead.. One of the best known DIY teeth whitening methods is to perform baking soda teeth whitening.

People often question whether the whole baking soda method of whitening teeth works, and if so, how exactly?

Fortunately, there is some scientific research on the subject that shows us the best methods.

Baking Soda Teeth Whitening Methods

Below are 6 baking soda teeth whitening methods.

Baking Soda and Water

The most basic method is mixing baking soda and water. To do this use a small cup or bowl, mix a few drops of water with half a teaspoon of baking soda to form a paste. Once you have a paste, apply it to your teeth using a toothbrush or your fingers. Leave it on for approximately two minutes and then rinse thoroughly with water.

Baking Soda and Toothpaste

You can also try adding a small amount of baking soda directly to your toothpaste.

Baking Soda and Hydrogen Peroxide

Baking soda with another household product — hydrogen peroxide — make great partners to effectively whiten your teeth. Mix a teaspoon of baking soda and half a teaspoon of hydrogen peroxide until the mixture reaches a toothpaste-like consistency.

Baking Soda and Lime or Lemon Juice

Citrus fruits contain citric acid which is an effective bleaching agent. To use, mix half a teaspoon of baking soda with half a teaspoon of lime or lemon. Use your toothbrush to brush your teeth with the mixture. Let the mixture sit for a minute before washing off.

Don’t use this mixture too often as citric acid can be detrimental to the teeth due to the acid found in limes and lemons, twice a week should be fine.

Baking Soda and Apple Cider Vinegar

Rinsing your mouth with three parts water and one part apple cider vinegar makes a great teeth-whitening rinse. Mix it with toothpaste, and brush as you would normally. There are also many other ways to use apple cider vinegar for whiter teeth.

Coconut Oil and Baking Soda Mouth Rinse

Another way to save on expensive commercial whitening treatments and avoid harmful chemicals is to use coconut oil for teeth whitening in conjunction with baking soda.

Coconut oil is a good source of lauric acid, a saturated fatty acid that helps in reducing inflammation, wound healing and has anti-fungal properties.

When mixed with baking soda you have a paste that will whiten your teeth and prevent tooth decay.

Swishing coconut oil paste for a few minutes, this is also known as oil pulling. Just heat one cup of coconut oil until liquid-like, and add two teaspoons of baking soda.

How Long and How Often Should You Clean Your Teeth With Baking Soda?

Use baking soda to whiten teeth for no longer than two minutes at a time. Prolonged exposure to baking soda can erode your enamel. When you are brushing, make sure to brush your teeth the right way, especially with baking soda.

Afterward, rinse your mouth thoroughly with water or mouthwash. Do not forget to clean your toothbrush thoroughly aftward and ensure all oil particles are removed from the bristles.

You can repeat a baking soda teeth whitening method every other day for one or two weeks to give your teeth and enamel room to breathe and prevent enamel erosion.

How Fast Does Baking Soda Whiten Teeth?

Usually, results can be noticed in just a few days, but noticeable whitening can be seen after a couple of weeks. Other people may notice slight results as quickly as the first time they use baking soda on their teeth.

Are There Other Benefits of Using Baking Soda on Teeth?

Along with teeth whitening, baking soda can also help in maintaining general oral health. It can be a cheap temporary remedy for dental issues including bad breath, sores and ulcers, and gingivitis gum disease.

Baking Soda for Bad Breath

Baking soda can re-balance the acid levels inside your mouth, preventing and treating bad breath by destroying the environment inside the mouth where bacteria can flourish. Simply dissolve a half teaspoon of baking soda in a glass of water. Use this mixture as an oral rinse.

Baking Soda for Mouth Sores and Ulcers

Dissolve one to two teaspoons of baking soda in a glass of water and use it as a rinse. This will serve to soothe and help in the healing process.

Baking Soda for Gingivitis

Baking soda can help block the accumulation of plaque and aid in the avoidance of gum disease. Add a small amount of baking soda after putting toothpaste on your brush, then brush.

How to Safely use Baking Baking Soda for Whiter Teeth

Anything done to excess can be harmful.

Excessive use of baking soda could be harmful to your tooth enamel due to its abrasiveness.

For healthy use of baking soda as a teeth whitener, you only need about a pea-sized drop of sodium bicarbonate, just enough to cover the bristles of a wet toothbrush head. 

Gently brush the teeth with the baking soda for about a minute or two, ensuring it’s being applied at all angles, and in corners, in crevices, and on the surfaces of the teeth. Then, make sure to rinse.

Brush your teeth as usual with toothpaste after rinsing out the baking soda.

Do not use baking soda if you have braces or other non-removable dental correction devices.

If you notice tooth sensitivity or any other symptoms from using baking soda as a tooth whitener, make an appointment with your dentist.
