How will white strips effect my fake tooth?

I have a fake tooth that I got in a biking accident... the original tooth was chipped pretty badly so they drilled it off and left a stub and i guess they put a crown over that...so my whole front tooth is essentially fake. I'm interested in using white strips to make my teeth look whiter...(obviously). Will my fake tooth remain the same colour and not get any whiter? (my other teeth seem slightly less white than the fake tooth as it stands now anyways...). Also, what long term effects do white strips have on teeth? thanks.
