What should I do if my porcelain-fused-to-metal crown has turned black?

Examine the surface of the porcelain-fused-to-metal crown to determine the cause of the darkening. If the discoloration is due to an underlying dental issue, root canal treatment or other restorative procedures may be required. If structural damage to the crown is found, replacement of the crown will be recommended. This ensures both the appearance and function of the crown while preventing further discoloration. If the darkening is merely surface staining, teeth whitening treatments can be used. Professional whitening techniques can effectively remove surface stains and restore the crown's bright, white appearance.
