Brush your teeth as usual with a natural toothpaste or you can use the banana peel first and then brush.
Use a ripe banana as it has the most potassium content in it.
Take a piece of the inside of the banana peel and gently rub around on your teeth for about 2 minutes. The amazing minerals in the peel like potassium, magnesium and manganese absorb into your teeth and whiten them.
Repeat the same procedure at night or before bedtime, to whiten teeth.
Leaving the banana peel on longer is optional if you have stains that need to come off.
Do the banana peel routine twice daily to see teeth whiten.
