Can my canted smile be fixed with dental contouring?

I have an implant on #7 and 2 porcelain veneers on numbers 8&9. I also have a composite veneer on 6 to lengthen the tooth and one on #10 because the colors weren't matching. My question is I still have a cant on the right side. Is there a way to fix to without getting porcelain veneers? Would dental contour fix the cant? If I don't have to ruin healthy teeth for veneers I'd prefer not to.
