Would you consider Brushing your Teeth with Baking Soda?

Worried if it’s too abrasive and bad for your enamel?

In this post, I share the benefits of using Baking Soda to brush your teeth, how Baking Soda can help in your teeth whitening and the precautions when using baking soda.

Let’s dive in.

What does Baking Soda contain and why it may be good for your teeth?

Can you brush with baking soda?

I bet you should have baking soda in your kitchen, you use it for kitchen cleaning and removing stubborn stains on pots.

But why not consider using on your teeth?

Baking soda contains mild abrasive, so when used on your teeth, it is able to remove plaque and surface stains, giving you white teeth.

Its chemical name is sodium bicarbonate, which means it is saltish and alkaline.

You can give it a test by using a cotton pad, wet it with some baking soda, and rub on the obvious stains. Baking soda is slightly saltish, so it is good to be used against acid-causing food elements like coffee.

A study from ADA showed that Baking Soda is effective for stain removal and whitening, so you can definitely put your mind at ease.

Of course, do not use on children as their teeth are still developing.

If you want to benefit from using baking soda for whitening your teeth, read on.


Types of stains on your Teeth

There are 2 types of stains that occur on your teeth.


This is caused by factors such as your age, health conditions or the type of medications that you are taking. Tooth infections left untreated can also lead to the slow eroding of your enamel.



This is caused by the foods that you consumed, like coffee, tea and coloured drinks.

These stains usually occur on tooth surfaces and if your enamel is porous and rough, the stains will stay on longer.


Looking at RDA – Relative Dentine Abrasion

When we look at abrasiveness, it is the degree of polishing a hard surface such as your teeth. This is measured in RDA – Relative Dentine Abrasion

Started in 1976, RDA Is a measure from 0 to 250 on the level of abrasiveness a toothpaste can potentially have.

Source : RDA

This is the standard by ADA to measure the abrasivity in toothpastes. The higher the RDA, the higher the degree of abrasiveness.

Toothpastes over RDA 250 have been removed from the market.

The website says that it does not mean a toothpaste of 250 is bad compared to a toothpaste of under 100.

In terms of expecting better results for stain removals, go for those with more than RDA100.

The factors that determine tooth wear and tear are due to abrasion (which you can control in the toothpaste that you use on a daily basis), attrition (tooth to tooth contact) and erosion of enamel.

A lot of factors will go into the wear and tear, like diet, lifestyle and individual health conditions.

You want your toothpaste to be abrasive to remove the stain but not harsh enough to erode your enamel.

Enamel once eroded is hard to grow back, that is why you need to make a conscious effort to protect it.

You can see that brushing with water alone has an RDA of 4.  That is great.

Brushing with baking soda comes next at 7.


Advantages of Brushing with Baking Soda

Using Baking Soda to brush your teeth
  • It does not contain any chemicals common in toothpaste such as fluoride which many have come to reject as a possible toxin.
  • Cheap and easily available in the kitchen
  • Saves money on buying tubes of toothpastes
  • It can remove plaque and surface stains.
  • Kills bacteria, thus preventing bad breath

With manufacturers increasing use of baking soda into their toothpastes, you may then want to reap the benefits of baking soda where it is added to toothpastes.

Best Baking Soda Toothpaste

A great example of toothpastes that uses baking soda is from Arm and Hammer.

Toothpaste with baking soda

Arm and Hammer Advance White™ Extreme Whitening Toothpaste.

This toothpaste is formulated with peroxide to give extra cleaning and whitening powder.

The low-abrasion formula will ensure that your enamel is safely protected. And its RDA is 42, under the safe RDA of 0-70.

Baking Soda for Sensitive Teeth

If you have sensitive teeth, that is because the layer of teeth beneath the enamel, called the dentine, has been exposed.

The porous surface on the dentine is linked to the nerves of your body. Whenever you consume foods that are hot or cold, these nerves are irritated, sending pain messages to your brain.

Sensitive teeth can be caused by many reasons such as tooth decay, overconsumption of sugars leading to enamel wearing off, gum diseases and receding gums.

So for you to use baking soda, you have to be extra careful as you do not want further possible abrasion.

Choices for you are using a soft toothbrush, choosing a gentle toothpaste that still contains baking soda like the Arms and Hammer Sensitive teeth and Gums here.

Other advice could be to avoid extremely hot or cold foods, using a mouth guard at night while sleeping and rinsing with fluoride.

Is Baking Soda Good for Brushing Teeth?

When baking soda comes into contact with water, it becomes an alkaline solution.

This solution can neutralise the acidity in your mouth, thereby helping you to remove bacteria that causes bad breath.

However, you should not brush for too long using baking soda. Be sure to use a soft bristle (my recommended one is this) and with the proper brushing technique.

Also, rinse with a good mouthwash (I made my own mouthwash with this), and wash your toothbrush in a cup to rinse off any residue.


How Often should you brush your teeth with Baking Soda?

A little under 2 minutes each time is sufficient, and do it 3 times a week.

Disadvantages of Brushing your Teeth with Baking Soda

  • Messy to mix up the paste. If your container is shallow, only your brush head can be dipped into the container.

Then you will have the baking soda on one part of your toothbrush only.

  • It does not contain fluoride to prevent tooth decay.
  • It is abrasive if you brush against your teeth too hard.
  • It does not contain mint so you may not have the fresh breath.
  • Not approved by ADA – American Dental Association
  • It does not foam up as a toothpaste does. You may not get used to the gritty texture of the baking soda. Even when you mix with coconut oil, it is still separated at the bottom of the mixture. The consistency can be runny and powdery.

How fast does Baking Soda whiten teeth?

The results vary, but there are success cases with days, if not weeks. The important thing to note is not to carry on the bad habits of drinking coffee, tea, and also smoking.

This is to ensure maximum success for baking soda.


What else can I use with Baking Soda? 

You need not be confined to using Baking Soda alone.

To add variety to an otherwise salty taste of baking soda, consider using lemon, hydrogen peroxide and essential oil. Coconut oil is also a favourite ingredient as it contains lauric acid to remove harmful bacteria and it can also whiten teeth naturally.

Now, who says custom-made toothpaste has to be boring?

FAQ on Using Baking Soda for Your Teeth

1.Is it safe to use Baking Soda every day?

No, do not use it every day. The recommended is two times a week.

Baking Soda contains a certain level of abrasiveness. If you already have receding gums, do consider brushing very gently, so as not to aggravate your receding gums.

Read this post to help with your receding gums.

3. What are the side effects of brushing with Baking Soda?

Excessive use of baking soda can have a negative effect on enamel. The constant wearing down of enamel can happen if you brush too hard using a hard bristles toothbrush.

Less is more when it comes to reaping the benefit of baking soda.

4, What is a typical dentist opinion on baking soda?

Dentist opinions differ from place to place, but the common point is that dentists will still prefer to recommend the traditional way of brushing and flossing, using ADA approved products.

Not forgetting the routine dental visits.

While some may support using baking soda, they still caution the need to incorporate a level of fluoride in your toothbrushing routine.
