Brushing your teeth is an essential part of maintaining good oral hygiene. It helps remove plaque, prevent cavities, and keep your breath fresh. While most people use toothpaste to brush their teeth, there is a growing trend of using baking soda as an alternative. Proponents of this method claim that baking soda can whiten teeth, remove stains, and freshen breath. However, there is a lot of misinformation surrounding this topic. In this article, we will debunk the myth and explore whether you can brush your teeth with baking soda.

The Science Behind Baking Soda

Baking soda, also known as sodium bicarbonate, is a white crystalline powder with various uses. It is commonly used in baking as a leavening agent, but it also has many other applications, including cleaning and deodorizing. Baking soda is alkaline in nature, which means it has a high pH level. This alkalinity allows baking soda to neutralize acids and break down proteins, making it an effective cleaning agent.

When it comes to oral health, baking soda has been touted as a natural remedy for various dental issues. Its abrasive properties are believed to help remove plaque and stains from the teeth. Additionally, baking soda’s alkalinity can create an unfavorable environment for bacteria, reducing the risk of tooth decay and gum disease.

The Benefits of Brushing with Baking Soda

While there is limited scientific research on the specific benefits of brushing with baking soda, some studies have shown promising results. Here are some potential benefits of using baking soda as a toothpaste alternative:

  • Whitening: Baking soda’s abrasive properties can help remove surface stains from the teeth, making them appear whiter.
  • Plaque removal: Baking soda’s abrasive nature can aid in removing plaque, which is a sticky film of bacteria that forms on the teeth.
  • Bad breath prevention: Baking soda’s alkalinity can help neutralize odors and freshen breath.
  • Reduced acidity: Baking soda’s alkaline properties can help balance the pH level in the mouth, reducing acidity and creating an environment less favorable for bacteria growth.

While these benefits may sound appealing, it is important to note that using baking soda as a toothpaste replacement is not without risks. Let’s explore some of the potential drawbacks.

The Drawbacks of Brushing with Baking Soda

While baking soda may offer some benefits for oral health, it is not a perfect solution. Here are some potential drawbacks of using baking soda as a toothpaste alternative:

  • Abrasive nature: Baking soda is more abrasive than regular toothpaste, which means it can potentially wear down the enamel if used excessively or with too much force.
  • Alkalinity: While baking soda’s alkalinity can help neutralize acids in the mouth, excessive use can disrupt the natural pH balance, leading to oral health issues such as dry mouth and increased risk of cavities.
  • Lack of fluoride: Most toothpaste contains fluoride, which is essential for strengthening tooth enamel and preventing tooth decay. Baking soda does not contain fluoride, so using it as a toothpaste replacement may increase the risk of cavities.
  • Taste and texture: Baking soda has a salty and gritty taste, which may not be pleasant for everyone. Its texture can also feel abrasive and uncomfortable for some individuals.

Considering these potential drawbacks, it is important to use baking soda with caution and in moderation. It is always best to consult with a dentist before making any significant changes to your oral care routine.

How to Safely Use Baking Soda for Brushing

If you decide to incorporate baking soda into your oral care routine, it is crucial to do so safely. Here are some tips for using baking soda for brushing:

  • Mix with water: To reduce its abrasiveness, mix a small amount of baking soda with water to form a paste. This will help dilute the baking soda and make it gentler on the teeth and gums.
  • Use a soft-bristled toothbrush: Using a soft-bristled toothbrush will help minimize the risk of enamel erosion and gum irritation.
  • Brush gently: Apply the baking soda paste to your toothbrush and brush your teeth gently in circular motions. Avoid applying excessive pressure, as this can damage the enamel.
  • Rinse thoroughly: After brushing with baking soda, rinse your mouth thoroughly with water to remove any residue.
  • Alternate with regular toothpaste: To ensure you are still getting the benefits of fluoride, consider alternating between using baking soda and regular toothpaste.

By following these guidelines, you can minimize the potential risks associated with using baking soda for brushing.

The Bottom Line

While baking soda may offer some benefits for oral health, it is not a substitute for regular toothpaste. The American Dental Association (ADA) recommends using toothpaste that contains fluoride to prevent tooth decay and strengthen tooth enamel. Baking soda can be used as a supplementary oral care product, but it should not replace your regular toothpaste.

If you are considering using baking soda for brushing, it is important to consult with a dentist first. They can assess your oral health needs and provide personalized recommendations. Remember, maintaining good oral hygiene involves more than just brushing your teeth. It also includes flossing, using mouthwash, and visiting your dentist regularly for check-ups and cleanings.


Brushing your teeth with baking soda may have some benefits, such as whitening and plaque removal. However, it is important to use baking soda with caution and in moderation. Its abrasive nature and lack of fluoride can pose risks to your oral health if not used properly. It is always best to consult with a dentist before incorporating baking soda into your oral care routine. Remember, maintaining good oral hygiene involves a comprehensive approach that includes regular brushing, flossing, and dental check-ups.
