We all want brighter smiles. Sadly, that often means harsh chemicals and expensive treatments. However, there is a way to naturally whiten your teeth with just one ingredient.

Rub the inside of a banana peel directly on teeth. (The fresher the banana the better). Leave the banana residue for ten minutes, avoiding touching it with your lips. Brush your teeth with water or toothpaste. The magnesium, manganese and potassium will absorb into your teeth and brighten them. There won't be obvious results after one application, but in a week or so, you should see a significant difference.
