DIY Teeth Whitening with Hydrogen Peroxide and Baking Soda

Making a DIY teeth whitening paste with hydrogen peroxide and baking soda is a common method to address minor tooth discoloration. Mix 1-2 tablespoons of baking soda with hydrogen peroxide to form a paste, then gently brush your teeth for 1-2 minutes. Rinse thoroughly. However, this should be done sparingly and cautiously, as overuse can lead to tooth sensitivity and enamel erosion. Consult a dentist before attempting any DIY teeth whitening, as professional treatments are often more effective and safer for significant results.

Long Version

Teeth whitening is a common cosmetic dental procedure aimed at brightening the color of one’s teeth. While there are various professional treatments available, many individuals seek DIY methods for teeth whitening. One popular DIY approach involves using a mixture of hydrogen peroxide and baking soda to create a homemade teeth whitening paste.

How it Works:

The premise behind using hydrogen peroxide and baking soda for teeth whitening is relatively straightforward. Hydrogen peroxide is a bleaching agent that can help break down and remove surface stains on teeth. Baking soda, on the other hand, is mildly abrasive and can aid in scrubbing away stains. When combined, they create a paste that can potentially help whiten teeth by addressing some of the common causes of tooth discoloration, such as stains from food, beverages, and smoking.

Ingredients and Preparation:

To make your own teeth whitening paste, you’ll need the following ingredients and materials:

  1. Baking Soda: This is the abrasive component that helps remove stains and plaque.
  2. Hydrogen Peroxide: This acts as the bleaching agent to whiten teeth.
  3. A Small Container: You’ll need a small dish or container to mix the ingredients.
  4. Toothbrush: You should use a soft-bristle toothbrush for this purpose.

To create the paste, mix 1-2 tablespoons of baking soda with enough hydrogen peroxide to form a thick paste. The paste’s consistency should be similar to toothpaste. Be cautious not to swallow the mixture, and if you accidentally do, seek medical attention immediately.


  1. Apply the homemade paste to your toothbrush.
  2. Brush your teeth gently with the paste for 1-2 minutes. Be careful not to use excessive force, as aggressive brushing can harm your tooth enamel.
  3. Rinse your mouth thoroughly with water to remove any residue.

It’s important to emphasize that this method should be used occasionally and not as a daily teeth-cleaning routine. Overuse of the hydrogen peroxide and baking soda mixture can potentially lead to tooth sensitivity and enamel erosion, which may result in more harm than good.

Precautions and Considerations:

Before attempting any DIY teeth whitening method, it is highly recommended to consult with a dentist. They can assess your dental health and provide guidance on the safety and effectiveness of the chosen approach. Additionally, certain individuals may not be suitable candidates for DIY teeth whitening, especially if they have gum disease, tooth decay, or dental restorations (e.g., crowns, veneers) that do not respond to the whitening agents.

It’s also worth noting that while this DIY method can help remove some surface stains, it is not as effective as professional dental treatments. Dentists can offer various professional teeth whitening options, including in-office procedures and take-home kits, which can yield more noticeable and long-lasting results.

In conclusion, making your own teeth whitening paste with hydrogen peroxide and baking soda is a popular DIY method for addressing mild tooth discoloration. However, it should be used cautiously and sparingly, with careful consideration of your overall dental health. Consulting with a dentist and considering professional treatments may be a more effective and safe approach for achieving significant teeth whitening results.
