DIY Mouthwash with hydrogen peroxide?

Hydrogen peroxide is a three percent aqueous solution of hydrogen peroxide. It has mainly disinfecting and bactericidal properties, so we often use it to disinfect small wounds and scratches. 

It is also used in cosmetics: high concentration of hydrogen peroxide is used for lightening hair, depilation, and for washing acne-prone skin. 

It has a brightening and whitening effect on teeth, it is widely used in the dental industry for professional teeth whitening. This is where the ideas for her home oral hygiene came from. 

Hydrogen peroxide is a great addition to household mouthwashes: it is cheap, readily available, and very effective. 

However, remember that, like any home cosmetics, you have to use it carefully: do not swallow it (it is poison) and do not overdo it in everyday use (it is a strong oxidant and can damage our tooth enamel).

Where to buy?

We can buy ordinary hydrogen peroxide in a concentration of 3% at any stationary pharmacy, but most of us have it already in our home medicine cabinet.
