Dental Whitening? I have dental work on the front of my front tooth. Will the whitener whiten it too?

Or will I have white teeth and a yellow spot where my dental work is at? And what is the best OTC whitener?
--------------------
Dental work? As in veneers or caps? If that is the answer then nothing will whiten artificial teeth. They have to be white as you desire to start with. You teeth will whiten just fine just not artificial teeth. Crest white strips work very well but sometimes takes more than one box to get the desired color.
