Although the teeth around the fillings will lighten, the fillings themselves and crowns will not whiten to the same extent. Some whitening of tooth-coloured restorations may occur but ceramic fillings and crowns will not change in colour. Any tooth-coloured restorations on your front teeth will need to be replaced after the whitening procedure.
Any surgical or invasive procedure carries risks, and we recommend seeking a second opinion from an appropriately qualified health practitioner before proceeding.
