Does Bleaching work on all discoloured teeth?
Teeth with a yellowish hue usually bleach well, brownish ones less so; grayish teeth may not bleach well at all. Discoloured filling will not improve with bleaching. They will show more if the surrounding tooth structure is bleached and thy may have to be replaced. Your dentist will be able to tell you whether bleaching is suitable for you and discuss other options such as veneers and crowns for improving the appearance of your teeth.
