of getting your teeth whiter by using natural products without getting them chemically whitened ?

it would probably depend on the product.

natural methods, nope, just a bit of cheese each day, no black tea , coffee, red wine or ciggies, a tartar control toothpaste

and if all else fails ? apply some tippex(kidding)

actually any dentist will tell you, slightly yellow teeth are healthier than all white!

Brush and gargle with peroxide. just dont swallow it! its tasteless and really does whiten your teeth.
