Baking soda and peroxide to whiten teeth

Hydrogen peroxide can definitely whiten teeth, but it needs to be used under very specific conditions that simply aren’t these ones. Most importantly, hydrogen peroxide has to be much stronger than the stuff in the brown bottle. It also has to be completely isolated against your teeth because of how weak it is – even saliva breaks it down and stops it from working!

Make a hydrogen peroxide and baking soda paste.
Using a paste of hydrogen peroxide and baking soda
can whiten your teeth and soothe sore gums.Brush with the paste daily or
use it a couple of times a week like a mask.
Make sure you’re using 2–3.5% hydrogen peroxide.
Put a couple of teaspoons of baking soda into a dish.
Add a small amount of the peroxide and mix it with the baking soda.
Keep adding a small amount of peroxide until you have a thick-ish paste.
Brush the paste onto your teeth in small, circular motions for two minutes.
You can also apply it with your fingertips to stimulate your gums.
Brush with the paste for a couple of minutes or leave it on your teeth for
a few minutes for best results.
Rinse the solution off of your teeth by swishing with water
