What happens when you mix toothpaste and hydrogen peroxide?

Mixing toothpaste with hydrogen peroxide can create a foaming "Elephant's Toothpaste" reaction if a catalyst (like yeast or potassium iodide) is added, producing oxygen and foam, or it can be used in commercial products for gentle whitening by breaking down stains, though overuse can cause sensitivity or enamel erosion. While it helps lift stains and fight bacteria, the mixture's effectiveness and safety depend on concentrations, with commercial toothpastes carefully formulated, but DIY mixes risk enamel damage or gum irritation, so caution is advised.

Can you mix hydrogen peroxide with toothpaste?

Is hydrogen peroxide in toothpaste harmful?

What does brushing your teeth with hydrogen peroxide do?
