Hydrogen peroxide, or hydrogen peroxide as it is commonly known, is a natural bleach that has the effect of disinfecting wounds and killing bacteria. Across online platforms like YouTube or TikTok, there are endless videos where people use oxygenated water as a home treatment to whiten teeth. Does it work?

Healthline - one of the safest sources for health - writes that many commercial teeth whitening products contain hydrogen peroxide, albeit in a much higher concentration than the product you can buy at the pharmacy.

Unfortunately, no study has investigated the effects of rinsing or brushing teeth with hydrogen peroxide, but some studies have analyzed commercial toothpastes that contain peroxide. A study found that a toothpaste containing baking soda and 1% hydrogen peroxide made teeth whiter than other toothpastes, writes Healthline.

But you should keep in mind that although very dilute concentrations seem safe, strong concentrations or overuse can cause gum irritation and tooth sensitivity.

One way to use hydrogen peroxide is to clean your mouth before brushing your teeth. Make sure you are using a 1.5% or 3% solution to avoid side effects.

Another way to use hydrogen peroxide is by mixing it with baking soda to create a paste Combine 2 teaspoons of hydrogen peroxide with 1 teaspoon of baking soda and gently brush your teeth with the mixture.

Careful! Limit the use of this paste, as excessive use can erode tooth enamel.
