Which Teeth Whitening Active Ingredient Is Better: Hydrogen Peroxide or Activated Charcoal?

Teeth whitening is a common routine, and the top two methods are with hydrogen peroxide and activated charcoal. Many debate over which method is better. Both have advantages and disadvantages that make them unique, but which one should you prefer? 

Hydrogen Peroxide

Dentists use it for teeth whitening procedures in their facilities, but you can also buy a bottle for DIY teeth whitening at home. You can either use it as a stand-alone remedy or add it to other substances to make pastes.

The amount used in commercial whitening varies in concentration and can be up to 10%. The one for home remedy is a bit softer and contains only 6% hydrogen peroxide. 


Hydrogen peroxide is widely available and easy to use; you can do it yourself. All you need to do is apply it to your toothbrush and brush your teeth like normal.

The second advantage is that this product is also versatile; you can mix it with other products like baking powder and strawberry to make a homemade paste.


Hydrogen shouldn’t be used too often in long durations because excess of it can penetrate the enamel and the collagen-rich tissue in the dentin damaging your teeth in the process. Higher concentration may be safe for professional teeth whitening because of the protection given to the gums at the facility.

Activated Charcoal

Activated charcoal is a typical powder from burning wood or coconut that goes through various processes to give it an extensive surface area and enhance its absorptive qualities. 


The adsorptive and abrasive qualities make activated unique and potent teeth activating remedy. It cleans all types of materials on your teeth, including persistent stains, food debris, and bacteria. Incorporating this item in your routine helps remove stains and brighten your smile.

Activated charcoal is inexpensive and readily available in local pharmacies and even some grocery stores. You can use it independently or opt to mix it with your regular toothpaste for the best result. Whichever method you pick, it is much cheaper than an in-office whitening treatment. 


While many advocate for charcoal as a great way to whiten your teeth, there is little scientific backing behind these claims. While hydrogen peroxide has scientific studies to support its efficacy, charcoal lacks these. Also repeated usage of activated has been proven to weaken your teeth over time.

Final Thoughts

While both are great at cleaning and whitening teeth, hydrogen peroxide come out on top because it has more proven results and causes less harm to your teeth. It is an ideal remedy for both home and professional application.
