How to correct asymmetrical smile?

You are correct that the right side of you smile is leaning in and displaying more darkness, gum tissue and less teeth--The correction is less about your cheek than the teeth themselves. in simple terms the teeth can be brought out orthodontically or with porcelain or composite reshaping. An orthodontic approach is more ideal but either will give you great improvements esthetically. Good luck!

you have two options,the best one is to do braces and to bring that bite to a correct position,the situation is that at the end you will have a good oclusion,but you will still have the same teeth,with the same shape,size and color,and it will take up to 1 year aprox.now if you do not want to have braces or having braces is not part of your plans,you can have a different alternative solution,which is Smilemakeover,where you will be having a full mouth change in just a couple of days and change your life!,and you will certainly will have also good results with several techniques involved,and you will be changing shape,size and color.
