When you lay out in the sun or go to a tanning bed...?

Question

Could either of those whiten your teeth if you show them to either of those?

Answer 1

No---teeth are a different surface and are not affected by the sun. They could appear whiter, though, if your skin is darker because of the resulting tan.

Answer 2

you need to buy Britey Whitey's they sell them int anning salons.

Its a special paste you put on your teeth before you tan and it whitens your teeth. It comes with a mouth guard that keeps your mouth open.

Unfortunatly UV light alone does nothing to your teeth without the special product that is removing the stains.

many tanning salons sell the "Britey Whitey's" kit its about $30

Answer 3

Hope this question isn't a joke ;)

Anyway - here goes

I am unaware of any scientific study on the effect of light on teeth. Sunlight basically induces the skin to produce of melanin which gives the brown colour to the skin. Taking an intelligent guess, the ultra violet, infrared and visible light rays don't seem to have any effect on the colour of the teeth and I am unaware of teeth producing melanin or any bleaching compounds on exposure to the constituents of sun light.

On second thoughts, Sunlight is known to fade colour on clothes, perhaps it may be worth a try for someone to try the same with teeth :P
