How do I get that pretty, wide, smile, showing big beautiful teeth? My smile is too small for my face (Photo)

Smile width is dependent on the width of your bone structure.  Some people just have narrow dental arches.  If this is the case with you than any major expansion will be very unstable...

The information you have provided is inadequate to determine if some kind of orthodontic treatment would help broaden your smile. I treat patients every day who want broader prettier smiles. Sometimes this can be accomplished with orthodontic/orthopedic treatment while other times it is more appropriate to use cosmetic restorations. I suggest you talk with a cosmetic dentist who understands orthodontic/orthopedic treatment in order to determine the best course of treatment to accomplish your goals.Good luck!
