I have read your problem. As you are telling that your orthodontist asked you to get 4 teeth extracted and due to enormous faith on orthodontist you did what was advised . you got four bicuspids(1 premolars) extracted and that indeed proved to be fatal.. Your doc pushed all front teeth backwards which resulted in degradation of facial aesthetics. Some of the consequences are your lower jaw gone backwards ,less protruded chin ,sharp jawline is gone. In fact now when you smile teeth are not visible at all Unless you have to strain lips, face has got flattened,decreased facial volume ,narrow dental arc etc. are few of the many damage due to extractions.... So I am advising you go to the oral surgeon hospital who are routinely doing orthognathic surgeries,he is the only person who can improve your face.Through ORTHOGNATHIC surgery
face can bring forward ,then if artificial tooth needed ,it can be decide later on.
All the best.
