Does baking soda whiten teeth?
Yes, it’s true — baking soda can 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 eliminate tooth discoloration due to food and drink consumption, smoking, and the like.
Due to the mild abrasiveness, it removes plaque on the tooth’s surface.
Many, if not everyone, want whiter teeth.
The desire to achieve a pearly white smile has brought in 11 billion US dollars revenue for the teeth whitening industry, with the annual spending on teeth whitening products recording at approximately 1.4 billion US dollars.
For some people, in-office teeth whitening is cost-prohibitive. That’s why many people are looking for DIY at home tooth whitening methods. One of the most known ways to whiten teeth at a lesser price is to use baking soda.
People often question whether the whole baking soda method of whitening teeth works. Fortunately, there is plenty of scientific research and you’ll soon know if using baking soda to achieve pearly white smile is really possible. Below are 6 ways to use baking soda for teeth whitening.
6 Ways to Whiten Your Teeth With Baking Soda
#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. Leave on for approximately two minutes and rinse with water.
#2 Baking soda and Toothpaste
You can also try adding a little amount of baking soda to your toothpaste. Or, you may purchase a ready-made toothpaste that contains baking soda as an ingredient.
#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 detrimental to the teeth due to the acid found in limes and lemons.
#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 to utilize a coconut oil paste on your teeth. Coconut oil is a good source of lauric acid, a saturated fatty acid that helps with weight loss and 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 at a time. Prolonged exposure to baking soda (a mild abrasive) can erode your enamel. When you are brushing, make sure to apply the right tactics when brushing, especially baking soda.
Afterward, rinse your mouth with water or mouthwash. Do not forget to wash your toothbrush 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 just a few days, but noticeable whiteness can be seen after a couple of weeks. Others may notice slight results after the first time they use baking soda on their teeth.
What Are 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 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
For mouth sores and ulcers, dissolve one to two teaspoons of baking soda in a glass of water. This will serve as an 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 or two, ensuring it’s being applied at all angles, corners, crevices, and surfaces of the teeth. Then, rinse.
Leaving it on too long or using it too often could lead to the tooth enamel’s erosion. Brush your teeth as usual with toothpaste after rinsing out the baking soda.
However, do not use baking soda if you have braces or another non-removable dental correcting device.
If you notice tooth sensitivity or other notable symptoms from using baking soda as a tooth whitener, make an appointment with a dentist. Be candid with your dentist regarding your experiences with baking soda, so they can best assist you.
