Does baking soda whiten teeth?

Yes, it’s true — baking soda can in fact help whiten your teeth!

Baking soda or sodium bicarbonate is a chemical compound that is white, crystalline, and often appears as a fine powder. It is made up of sodium and bicarbonate ions.

Baking soda has a salty, alkaline taste. Its alkalinity helps rid teeth discolorations due to food and drink consumption, smoking, among others.

Due to the mild abrasiveness, it removes plaque on the tooth surface.

Many, if not everyone, wants whiter teeth.

The desire to achieve a pearly smile has brought in 11 billion US dollars revenue for the teeth whitening industry with the annual spending on teeth whitening products recording at 1.4 billion US dollars.

But, not all can get in-office dental tooth whitening procedure because it’s expensive.

It costs 600 US dollars in average, meaning a minimum wage earner of 7.25 US dollars an hour needs to work more than 82 hours just to afford the procedure.

That, it is no longer surprising a lot of individuals are going for do-it-yourself home methods in tooth whitening. One of the most known ways to whiten teeth at a lesser price is with the use of baking soda.

People often question, when it comes to their teeth, whether the whole baking-soda-method of whitening teeth works, and if so, how exactly?

Fortunately, there is some scientific research done on this matter, and you’ll soon know if using baking soda to achieve pearly white smile is indeed possible.


6 ways on how to whiten teeth with baking soda?

Below are 6 ways to use baking soda for teeth whitening.

#1 Baking soda and Water

The most basic method is mixing baking soda and water. Using a small cup or bowl, mix a few drops of water with a half a teaspoon of baking soda to craft a paste. Once you have a paste, apply it to your teeth using a toothbrush or your fingers.

#2 Baking soda and Toothpaste

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

#3 Baking soda and Hydrogen Peroxide

You can partner baking soda with another household product — hydrogen peroxide — to effectively whiten your teeth. Mix a teaspoon of baking soda and a half teaspoon of hydrogen peroxide until the mixture turns into a toothpaste-like consistency.

Use the mixture to brush your teeth. Let it sit for a minute or two before rinsing it off with water. Make sure to rinse well and use a three-percent solution hydrogen peroxide for safety.

#4 Baking soda and Lime or Lemon Juice

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

However, limit the use of this mixture as citric acid can be more detrimental to the teeth due to the acid found in lime and lemon.

#5 Baking soda and Apple Cider Vinegar

Rinsing with three parts water and one part apple cider vinegar makes for a great, teeth-whitening rinse. Mix it with toothpaste, and brush as you normally would.

#6 Coconut Oil and Baking Soda Toothpaste

Another way to save up on expensive whitening treatments and avoid harmful chemicals is a coconut oil paste.

Coconut oil is a good source of lauric acid, a saturated fatty acid which helps with weight loss and in lowering cholesterol levels. Coconut oil also aids in addressing inflammation, healing wounds, and keeping the prostate healthy.

When mixed with baking soda and peppermint essential oil, you can have a paste that will whiten your teeth and prevent tooth decay.

Coconut oil is excellent for whitening the teeth thanks to its fatty acids. Swishing coconut oil paste for 20 minutes will do the trick. Just heat one cup of coconut oil until liquid-like, add 5-10 drops of spearmint essential oil, and add two teaspoons of baking soda.


How long and how often should you clean your teeth with baking soda?

Brush your teeth with the baking soda paste for not longer than two minutes as prolonged exposure to baking soda (a mild abrasive) can erode your enamel. When you are brushing, make sure to apply the right methods as when you are brushing with toothpaste to avoid destructive brushing.

Afterward, rinse your mouth with water or mouthwash. Do not forget to wash your toothbrush too thoroughly.

You can repeat the baking-soda-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?

Results can be noticed after a just a few days, but noticeable whiteness can be seen after a couple of weeks.


What are the other benefits of using baking soda on teeth?

Aside from teeth whitening, baking soda can also help in maintaining good oral health. It can be a cheaper temporary remedy for dental issues including bad breath, mouth sores and ulcers, and gum disease.

Baking Soda for Bad Breath

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

Baking Soda for Mouth Sores and Ulcers

For mouth sores and ulcers, dissolve one to two teaspoons of baking soda in a glass of water which will serve as your oral rinse to soothe and help in the healing process.

Baking Soda for Gum Disease

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


Is it safe to brush your teeth with baking soda?

Everything in excess can be harmful.

Excessive use of baking soda could be harmful to the enamel due to its abrasiveness. Also, baking soda is not a replacement for toothpaste as it does not contain cavity-fighting fluoride.

For a healthy use of baking soda as a teeth whitener, all you should need is about a pea-sized drop of the product, just enough to cover the bristles of a wet toothbrush head. Gently brush the teeth with the baking soda for about a minute, ensuring it’s being applied at all angles, corners, crevices, and surfaces of the teeth, and rinse.

Leaving it on too long or using it too often could lead to erosion of the tooth enamel. Brush your teeth as usual with toothpaste after rinsing out the baking soda.

If you notice tooth sensitivity or other notable symptoms from using the baking soda tooth whitener, make an appointment with a dentist. Do not use baking soda if you have braces or another non-removable dental correcting device.
