Does Baking Soda Whiten Teeth? The Truth to Know


|   Written by:


In the ever-evolving landscape of teeth whitening, natural remedies have garnered significant attention and intrigue. Among these remedies, baking soda stands out as a popular choice, often hailed for its purported teeth-whitening properties. This article seeks to explore the scientific validity of these claims, shedding light on whether baking soda can indeed whiten teeth.

For professionals in the teeth whitening industry, including dental spas, salons, and teeth whitening brands, understanding the potential of baking soda is essential to meet the demands of an increasingly health-conscious and eco-friendly consumer base.

The Chemistry of Baking Soda

Baking Soda’s Alkaline Nature

To comprehend how baking soda affects teeth, it is crucial to grasp its chemistry. Baking soda, scientifically known as sodium bicarbonate (NaHCO3), is a mild abrasive with alkaline properties. Its alkalinity makes it adept at neutralizing acids, potentially beneficial in combatting tooth discoloration caused by acidic foods and beverages. Additionally, the abrasive nature of baking soda can assist in removing surface stains, contributing to a brighter smile.baking soda raw materials

Baking Soda and Hydrogen Peroxide Synergy

One common approach to harnessing baking soda’s teeth-whitening potential is to combine it with hydrogen peroxide (H2O2). Hydrogen peroxide is a potent oxidizing agent capable of breaking down and bleaching stains on teeth. When baking soda and hydrogen peroxide are amalgamated into a paste, a chemical reaction ensues, liberating oxygen molecules. These oxygen molecules infiltrate the enamel and dentin of the teeth, degrading pigmented molecules responsible for staining.

Does Baking Soda Work as a Toothpaste?baking soda toothpaste

One question that frequently arises is whether baking soda can function effectively as a toothpaste. Baking soda possesses some characteristics of traditional toothpaste, such as its abrasive qualities, which help remove debris and stains. Moreover, its alkaline nature contributes to maintaining a balanced pH level in the mouth, which is essential for oral health.

However, it’s important to note that baking soda alone may lack certain elements found in commercial toothpaste, such as fluoride. Fluoride is a key ingredient for preventing tooth decay and strengthening enamel. Therefore, while baking soda can serve as an adjunct to oral hygiene, it may not fully replace conventional toothpaste for long-term daily use.

Can Baking Soda Be an Ingredient in Teeth Whitening Gel?

The synergy between baking soda and hydrogen peroxide has sparked interest in the formulation of teeth whitening gels. Many teeth whitening gels available in the market incorporate baking soda as one of their active ingredients. These gels aim to provide the benefits of baking soda’s mild abrasiveness and alkaline properties while combining them with the oxidizing power of hydrogen peroxide. As such, they offer a convenient and controlled way to apply baking soda for teeth whitening.can baking soda used in teeth whitening gel

The use of baking soda in teeth whitening gels allows for precise application, ensuring that the active ingredients reach the surface of the teeth efficiently. Dental professionals and teeth whitening brands often recommend these gels to clients looking for a natural approach to teeth whitening that can be used safely at home.

The Efficacy of Baking Soda Teeth Whitening

Supported by Clinical Studies

In the realm of dental care, empirical evidence holds paramount significance. While anecdotal endorsements of baking soda abound, it is imperative to scrutinize clinical studies and dental statistics to ascertain the true efficacy of baking soda as a teeth whitening agent.

Numerous studies have investigated the whitening potential of baking soda, often juxtaposing it with conventional toothpaste formulations. A study published in the Journal of the American Dental Association found that toothpaste containing baking soda and peroxide demonstrated a marked improvement in teeth whiteness compared to toothpaste bereft of these ingredients. The study also underscored the general tolerability of baking soda-based toothpaste among participants, implying its safety for usage.baking soda in oral cleaning

However, it is vital to acknowledge that the degree of whitening achievable with baking soda may fluctuate among individuals and may not match the results obtained through professional teeth whitening procedures, such as laser or chemical whitening.

Caution Regarding Tooth Sensitivity

An important caveat when considering baking soda for teeth whitening is the potential for tooth sensitivity. The abrasive quality of baking soda, if used excessively or with undue vigor, can lead to enamel erosion and heightened sensitivity. Dental professionals should caution clients and advocate for moderation when integrating baking soda into their oral care routines.

Pros and Cons of Baking Soda

While baking soda presents several advantages for teeth whitening, it also comes with its own set of pros and cons:


  1. Affordability: Baking soda is cost-effective and readily available, making it an accessible option for individuals seeking a budget-friendly teeth whitening solution.
  2. Natural and Chemical-Free: Many consumers appreciate baking soda’s natural and chemical-free nature, as it avoids the use of synthetic ingredients often found in commercial whitening products.
  3. Surface Stain Removal: Baking soda’s mild abrasiveness can effectively remove surface stains caused by coffee, tea, and red wine, leading to a visibly brighter smile.


  1. Enamel Erosion: Excessive use of baking soda or improper application can lead to enamel erosion, which may result in increased tooth sensitivity and other oral health issues.
  2. Variable Results: The effectiveness of baking soda teeth whitening can vary from person to person, and it may not provide the same level of whitening as professional treatments.
  3. Lack of Fluoride: Baking soda does not contain fluoride, a crucial component for strengthening tooth enamel and preventing cavities. Regular use of baking soda alone may not provide comprehensive oral care.

What Else Works for Teeth Whitening?

As dental professionals, salons, and teeth whitening brands explore natural teeth whitening alternatives, it is essential to consider other methods and ingredients that can complement or substitute for baking soda. Some effective options include:

1. Activated Charcoal: Activated charcoal has gained popularity for its ability to absorb stains and toxins. It can be used as a teeth-whitening agent in toothpaste or powder form.charcoal powder teeth whitening

2. Oil Pulling: This ancient practice involves swishing oil (usually coconut or sesame oil) in the mouth for several minutes. Oil pulling is believed to remove toxins and whiten teeth naturally.

3. Professional Teeth Whitening: For individuals seeking rapid and guaranteed results, professional teeth whitening procedures performed by dental experts remain a top choice. These procedures typically involve laser or chemical whitening methods, delivering noticeable improvements in a single session.

4. Whitening Strips and Trays: Over-the-counter whitening strips and custom trays prescribed by dentists offer convenience and predictable results. They often contain peroxide-based gels for effective whitening.

How to Deal With Stains That Cannot Be Removed By Baking Soda

While baking soda can be effective for many types of tooth stains, there are some stubborn stains that may resist its natural whitening properties. For challenging stains, dental professionals can offer the following solutions:

1. Professional Whitening: Dentists can provide in-office teeth whitening treatments that use advanced technology and stronger bleaching agents to target deep stains.

2. Veneers: For stains that cannot be removed by whitening, veneers can be considered. These thin shells are custom-made to cover the front surface of teeth, concealing imperfections.veneers

3. Bonding: Dental bonding involves applying a tooth-colored resin to the stained area and shaping it to match the natural tooth. This is a conservative option for addressing specific stains.

4. Lifestyle Changes: Dental professionals can advise patients on lifestyle changes to prevent further staining, such as reducing consumption of staining foods and beverages and maintaining good oral hygiene practices.
