I have dark stains at the gumline after porcelain crowns, can they be removed?

Are the crowns all porcelain or are they porcelain fused to metal crowns? If the crowns are porcelain fused to metal then a grey line will show that can not be removed. If it is your natural tooth that is dark due to stain then brushing with whitening toothpaste, or whitening may help.
