home teeth whitening

Can anyone tell me if the teeth whitening kits in their work home?
I wonder if the teeth whitening kits in the household work, and work on prosthetics share? So why is it that some people have naturally white teeth, and some are a shade below?
you definitely do not whiten your teeth. You can get kits ordered online and much less expensive than the dentist (who takes an impression of teeth and send them to the shelves), but perhaps not as white as the great pictures you think! I had some points that need to be dispatched at the dentist too. I know that does not work on crowns (my father launder teeth but the tooth crown was yellow) but I'm not sure best to consult a prosthesis prosthetics clinic first found you lose your money. my dentist I said all yellow teeth will gradually over time. I think the yellow color increases with snuff, coffee, etc. but some people are luckier than others.
