What should I do? Crowns to fix small bump after Invisalign. (photos)

Mistake! Just want old teeth back. I had a small unnoticeable bump only noticeable to me. I had Invisalign and it was still there. I went to another dentist to get second opinion about getting braces. They recommended 4 crowns. They did them but they came out grey and bump still there. She redid because I was unhappy we used another ceramics. she perm glued they looked ok at office now in pictures look crooked to me and wierd to me and are uncomfortable. Is it me or do these look wierd?
