The safest ways to whiten your teeth explained
Hydrogen peroxide is the main ingredient in most tooth whitening products. It's used in professional in-office treatment, over-the-counter teeth whitening products, and DIY home whitening.
Hydrogen peroxide is a common household item (you can find it in most first aid kits). It's a natural bleaching agent, antiseptic, and oxidizer. In its purest form, it's a light blue liquid with the chemical formula H2O2.
Hydrogen peroxide is commonly used to prevent infections in minor cuts, scrapes, and burns. It can also be used as a mouth rinse to remove mucus and relieve irritation due to gingivitis or canker sores.
Yes. Hydrogen peroxide is an effective tooth whitener.1
It has been used for decades and is backed by a significant amount of scientific evidence.

The two main ingredients you will see in teeth whitening products are hydrogen peroxide and carbamide peroxide.
Carbamide peroxide is a water-soluble, white crystalline solid compound. It is made of carbamide, also known as urea, and hydrogen peroxide.

At-home teeth bleaching products typically contain 5 to 10 percent hydrogen peroxide or 35 percent carbamide peroxide. They are applied for 10 to 30 minutes for multiple days in a row.
In-office treatments contain 25 to 40 percent hydrogen peroxide and stay on your teeth for a shorter time.
