Patrick R. Sexton, DMD (in memoriam)

Your question is a good one and unfortunately a common problem. My practice combines orthodontics and cosmetic dentistry to deal with this common issue. Bruxism complicates matters but can be dealt with.  
From your images, it appears your orthodontics has left you with a midline discrepancy, bimaxillary protrusion, and likely residual rotations of teeth. My recommendation would be to consider a second opinion on the progress of your orthodontics, followed by gingival contouring and possibly replacement laminate veneers.
