Hi, short background: I have had braces a long time ago (15 y ago). And then due to discoloration of one of the two front teeth, it was replaced by a porcelain tooth. I feel like my front teeth are too big in a way that it is not esthetically pleasing for me. Additionally I can’t close my mouth fully because of them. What can be done to make them smaller, would I need to replace all front teeth or can reshaping be done? All suggestions welcome. Please see photo.
