Its alkaline properties help to remove discoloration because of acidic foods.

Moreover, its abrasiveness deals with the plaque on the surface of your tooth.

There are several ways to whiten teeth using baking soda. We’ll discuss more of that later.

One such way is to use a toothpaste containing it.

Either, you can make your own toothpaste or certain toothpaste available in the market also contain sodium bicarbonate.

It is a safe method to whiten teeth as its hardness is similar to dentin while it is much less abrasive than whitening options like teeth whitening kit.

However, the process will be a little slow.

It can only remove extrinsic stains of coffee, tea, smoking and soda.

You will only see results after two to six weeks.

Baking Soda Benefits

Decreases bacteria inside your mouth 

Acidic conditions such as consuming acidic food and drinks can exacerbate the damage by bacteria.

However, sodium bicarbonate is alkaline.

Therefore, using it on your teeth helps to decrease the pH of the mouth and makes it less likely for the bacteria to multiply and attack your teeth.

This is more effective when you use a mouthwash with sodium bicarbonate.

Is a cost-effective option to whiten teeth 

Using sodium bicarbonate is a cost-effective way to whiten teeth.

You may have it right in your kitchen and can start using it immediately.

If not, then you can buy a box of baking soda from your nearby grocery store in a very cheap price.

However, remember to differentiate baking soda vs baking powder.

They are not the same thing! 

Baking powder has acids and cornstarch. It is popularly used in baking.

Baking soda is sodium bicarbonate that needs acid and warm water to act as a leavening agent producing carbon dioxide for baked goods.

Moreover, baking soda or sodium bicarbonate relieves acid reflux and neutralizes stomach acids in 15 minutes.

Because of its acidic content, baking powder is not a part of toothpaste.

Therefore, be careful while you make your purchase as acidic baking powder will rather harm your teeth.

baking soda decreases plaque

Decreases Plaque inside your mouth 

Plaque attaches to the surface of your tooth hence containing bacteria that can erode the enamel.

Therefore you can develop a tooth cavity and gingivitis as plaque accumulates on teeth.

However, sodium bicarbonate is an abrasive with antibacterial properties.

Therefore when you brush with it, its grains effectively remove plaque.

Hence, that disrupt the dental biofilm containing bacteria that attach to teeth thereby, reducing bacteria.

This can prevent gingivitis, cavities and yellow teeth.

It does not pose a risk of fluoride toxicity 

Fluoride toxicity is rare and is due to consuming a large amount of fluoride.

This is why parents avoid getting fluoride toothpaste for children under 6 years old.

It can cause vomiting, heart and kidney problems. Hence, it is a medical emergency.

However, if you make toothpaste with sodium bicarbonate, it will not contain fluoride.

Therefore you don’t have to worry about getting these fluoride-related risks such as fluorosis.

sodium bicarbonate side effects

Side Effects of Baking Soda

Sodium Bicarbonate is generally safe to use on the enamel and dentin.

There may not be any side effects but cons of using sodium bicarbonate on your teeth instead.

What are these? Let’s find them below!

Whitening is Minimal

Unlike other teeth whitening options like in-office Zoom teeth whitening or using a teeth whitening kit, teeth whitening at home is usually less dramatic.

You will only see results after four to 6 weeks, that too is very slight.

Whitening toothpaste that contains sodium bicarbonate can only whiten teeth by one shade.

Therefore, it will not provide you the results you need fastly.

But even if you use it regularly for a long period of time then it will not whiten your teeth dramatically.

Thus there are better alternatives for whitening than this.

Does not contain fluoride

Is this both an advantage and a disadvantage? Yes, it is.

Though excess consumption of fluoride in children can lead to fluorosis and there is always a risk of fluoride toxicity, it still helps prevent cavities.

Hence, fluoride in toothpaste protects from decay and cavities.

Though, if you make your own baking soda toothpaste then that doesn’t contain any fluoride.

Sodium bicarbonate cannot give as much protection against cavities as fluoride toothpaste.

Therefore, you will become susceptible to cavities and decay.

It Tastes Unpleasant

A sodium bicarbonate homemade toothpaste has granules that account for an unpleasant texture.

Moreover, it does not taste good either.

That does not make for good toothpaste.

However, you can make your way around using them.

Add a few drops of peppermint oil to enhance the flavor of the oil and make the taste bearable.

Or you could rather use a commercial toothpaste with bicarbonate soda if both taste and texture are bothersome.

Though, using it is harmless for teeth.

Summing Up 

Baking soda is generally safe to use however, it is:

  1. Not a replacement of toothpaste
  2. Not safe if used in excess
