Does Baking Soda Toothpaste Make Your Teeth Sensitive? 

Baking soda toothpaste can potentially cause tooth sensitivity in some individuals but this is not a universal reaction. Here’s a breakdown of how it might happen: 

Abrasive Nature

Baking soda (sodium bicarbonate) is a mild abrasive. While this abrasiveness is effective for removing surface stains and plaque, it can also wear down enamel if used too aggressively or too often. Thinner enamel can expose the dentin layer beneath, leading to increased sensitivity. 

pH Level

Baking soda is alkaline, which can affect the pH balance in your mouth. While this is often beneficial for neutralizing harmful acids, it might not be suitable for everyone’s oral chemistry. 

Individual Differences

Some people have naturally more sensitive teeth or thinner enamel, making them more susceptible to sensitivity from abrasive toothpastes. 

Improper Use: Using baking soda toothpaste too frequently, with too much force, or in combination with other abrasive oral care products can increase the risk of enamel wear and sensitivity. 

Underlying Dental Issues: If there are pre-existing dental issues like cavities, gum disease, or cracked teeth, using an abrasive toothpaste like one with baking soda can exacerbate sensitivity. 

According to the research conducted by Elsevier Science, baking soda is valued in toothpaste for its low abrasiveness, being softer than tooth enamel and dentin. However, baking soda toothpastes often contain additional ingredients that can increase their abrasiveness and stain removal effectiveness. While these ingredients enhance cleaning, they may also pose a risk to tooth enamel if too abrasive.

The key is balancing effective stain removal with enamel safety. The finding is that while baking soda is gentle, the overall abrasiveness of toothpaste depends on its complete formulation. (1) 

What is Tooth Sensitivity?  

Tooth sensitivity, medically known as dentin hypersensitivity, occurs when the enamel that protects our teeth gets thinner, exposing the underlying dentin. This exposure leads to discomfort or pain in your teeth when encountering certain stimuli, such as hot, cold, sweet, or acidic foods and drinks.

Symptoms of Tooth Sensitivity 

  • Sharp, temporary pain in the teeth when exposed to hot, cold, sweet, or acidic substances. 
  • Discomfort when brushing or flossing teeth. 
  • Pain when breathing in cold air. 

Common Causes of Sensitive Teeth  

Several factors contribute to the development of sensitive teeth, including: 

Enamel Erosion: Caused by acidic foods and drinks, overzealous brushing, or teeth grinding. Even, teeth whitening can damage enamel too. 

Gum Recession: Often a result of periodontal disease, leading to exposure of the sensitive root surface. Sometimes, Sensodyne toothpaste may cause gum irritation.

Tooth Decay or Broken Teeth: These can expose the sensitive inner layers of the tooth. 

Recent Dental Procedures: Sensitivity can temporarily increase after procedures like fillings, teeth whitening, or braces. 

The Role of Toothpaste Ingredients in Sensitivity  

Toothpaste ingredients play a crucial role in either causing or alleviating tooth sensitivity. Here’s how: 

Abrasive Agents: Some toothpastes contain abrasive ingredients that can wear down enamel over time, potentially increasing sensitivity. For example, Hello Toothpaste can make your teeth sensitive.

Desensitizing Ingredients: Certain toothpastes have ingredients like potassium nitrate or strontium chloride, which help block the transmission of pain signals from the tooth surface to the nerve. For example, sensitive toothpaste can make your mouth dry and cause other irritations.

Fluoride: This mineral helps strengthen tooth enamel, reducing the risk of sensitivity. But excessive use of fluoride can result in causing tooth pain.

Baking Soda in Toothpaste 

Baking soda (sodium bicarbonate) is a common ingredient in many toothpastes, known for its mild abrasive properties and ability to neutralize acids in the mouth. The question is, does its abrasive nature contribute to sensitivity, or does its acid-neutralizing capability protect against it?

The following sections will explore this in detail. 

What is Baking Soda (Sodium Bicarbonate)?  

Baking soda, or sodium bicarbonate, is a white crystalline compound that is mildly alkaline. It’s a versatile substance, commonly used in baking, cleaning, and personal care products, including toothpaste. Its alkaline properties make it effective in neutralizing acids, which is a key aspect of its role in oral hygiene. 

Historical and Current Use in Oral Hygiene  

The use of baking soda as a dental cleaning agent date back over a century. Historically, it was used as a simple, abrasive compound to remove plaque and clean teeth. Today, baking soda is incorporated into many toothpaste formulations for its ability to gently polish teeth, neutralize harmful acids produced by bacteria in plaque, and maintain a balanced pH level in the mouth. 

The Link Between Baking Soda and Tooth Sensitivity

Following are some details about the complex relationship between baking soda and teeth sensitivity.

How Baking Soda Works in Toothpaste?

Baking soda, or sodium bicarbonate, is a mild abrasive agent used in many toothpaste formulations. Its primary function is to mechanically scrub away plaque and surface stains from teeth, contributing to cleaner teeth and a brighter smile.

Additionally, its alkaline nature helps neutralize the acidic environment in the mouth, which is beneficial for preventing tooth decay and gum disease. 

The Potential Abrasive Nature of Baking Soda and Its Effects on Enamel  

While baking soda is considered a low-abrasive ingredient compared to other abrasives used in toothpaste, there is a concern about its long-term effects on tooth enamel. Enamel erosion can lead to increased tooth sensitivity, especially when consuming hot, cold, or acidic foods and drinks.

The key is in the concentration and the frequency of use; excessive use of baking soda or using it in a highly concentrated form could potentially wear down enamel over time. 

Expert Opinions and Dental Research Findings  

Dental experts and research studies provide mixed opinions on the link between baking soda toothpaste and tooth sensitivity.

Some studies suggest that when used correctly, baking soda toothpaste is safe for enamel and does not increase sensitivity.

Others caution that its abrasive nature, if not properly formulated, could contribute to enamel wear. The consensus is that baking soda toothpaste, when used as directed and in a formulation designed for sensitive teeth, is generally safe and effective for most individuals. 

Comparing Baking Soda Toothpaste with Regular Toothpaste 

Baking Soda Toothpaste: Known for its natural, mild abrasive properties, baking soda toothpaste effectively removes surface stains and neutralizes mouth acidity. It’s often praised for its natural ingredients and minimalistic approach to oral care. 

Regular Toothpaste: Typically contains a variety of ingredients, including stronger abrasives, fluoride for enamel strengthening, and sometimes specific compounds for sensitivity reduction. 

Pros and Cons of Using Baking Soda Toothpaste in Terms of Sensitivity 


Gentle Cleaning: Baking soda is less abrasive than some other commercial toothpaste abrasives, potentially reducing the risk of enamel wear. 

pH Balance: Its alkaline nature helps neutralize acidic conditions in the mouth, which can contribute to enamel erosion and sensitivity. 

Natural Approach: Often preferred by those looking for a more natural oral care product. 


Potential Abrasiveness: While milder, long-term use might still contribute to enamel wear if not used correctly. 

Lack of Fluoride: Most baking soda toothpastes do not contain fluoride, which is essential for enamel remineralization and preventing sensitivity. 

Limited Sensitivity Protection: Unlike specialized toothpastes for sensitive teeth, baking soda toothpaste may not offer targeted sensitivity relief.
