9 Inexpensive Ways to Whiten Teeth Fast

Charcoal

Charcoal acts as a magnet for stains within the mouth, and it will also whiten teeth (after leaving them a scary shade of black). The easiest way to do this is by buying a charcoal capsule and emptying the contents onto a toothbrush and then brushing the teeth. Charcoal tablets and capsules can be found in many whole foods or supplement stores across North America and can be used daily to clean the teeth.
