How to whiten teeth with hydrogen peroxide

Updated April 17, 2017

It can be expensive and time consuming to have your teeth professionally whitened. You can avoid the hassle and expense by whitening your teeth at home using hydrogen peroxide.

Regularly brush your teeth with a toothpaste that contains hydrogen peroxide. Many toothpastes now offer a whitening version of their original toothpaste so you can still use your favourite toothpaste while simultaneously whitening your teeth.

Make your own whitening toothpaste with hydrogen peroxide. An old and trusted way of whitening the teeth with hydrogen peroxide is to make your own toothpaste by blending hydrogen peroxide with baking soda until you have formed a paste. Brush your teeth with the peroxide, baking soda paste and thoroughly rinse out your mouth. Be careful not to swallow any of the paste.

Use whitening strips or gel that contain hydrogen peroxide. You can purchase over the counter teeth whitening kits that use hydrogen peroxide as the main ingredient for whitening your teeth. You will usually apply a strip to your teeth or fill a mould with a hydrogen peroxide gel solution that you hold on your teeth for a period of time. These methods may be briefly uncomfortable but if it works it might be worth it!

Warning

Never swallow hydrogen peroxide. Do not use food grade hydrogen peroxide orally.
