Does bleaching also work on fillings and crowns?
No. professional tooth whitening only works on the natural tooth substance. Your dentist will advise you if tooth bleaching is suitable for you, and if fillings and crowns need to be replaced. You may be asked to fill in a cosmetic treatment questioner as part of your initial assessment, as other options such as veneers and crowns may be more suitable or a combination of all three to achieve the best result.
