How can I whiten my teeth at home?

I have a tooth that was replaced and it is a off grayish color. I hate that it is so obvious and I was wondering if anyone knew how to get it white?

Whitening your teeth can be embarrassing, especially if the patient is embarrassed about the current state of the smile. This excruciating embarrassment can be avoided with at-home whitening treatments that allow the patient to whiten their teeth with professional and effective treatments that are applied in your own home. If you are able to receive the same quality as a trip to the dentist's office, why waste hundreds and even upwards of one thousand dollars on a whitening treatment that is just as an effective as an at-home treatment that can cost a fraction of the price? i,ve used Altra White too and i'm satisfied too: http://www.teethwhiten.com/?aid=823489
