How to make your own hydrogen peroxide teeth gel at home

Updated April 17, 2017

Teeth naturally become dulled and stained over the years, even with proper dental care. Professional whitening can cost hundreds of dollars, and at-home treatments are quite costly as well. You can make a simple whitening gel at home with products that you likely already have. Using a homemade teeth-whitening gel is an effective way to achieve a bright smile without spending money on professional treatments or store-bought remedies.

Mix 1 tsp of baking soda with 3 drops of glycerine in a cup until a paste forms. Glycerine is available in most grocery stores and pharmacies.

Add 2 tbsp of hydrogen peroxide to 1 cup of water in a glass and stir with a spoon. Higher concentrations of hydrogen peroxide will produce quicker whitening results. Hydrogen peroxide is usually available in stores in three per cent and 12 per cent concentrations.

Wet a toothbrush with the hydrogen peroxide solution, then dip it in the baking soda paste. Brush your teeth vigorously, re-wetting the brush in the hydrogen peroxide solution periodically.

Rinse out your mouth using the remaining hydrogen peroxide solution. Perform the whitening procedure at least three times per week until the desired results are achieved.


Rinsing your mouth with a hydrogen peroxide solution also helps kill bacteria that can lead to problems such as gum disease.
