How can I "even" out the line of my bottom row of teeth? (Photo)

Yes, this photo is exaggerated and no one actually smiles like this. The point is to clearly show the slant caused by the varying sizes of the lower teeth. I am wondering what sorts of cosmetic treatments are available to "even" out the line so that the bottom row of teeth have an even horizon. Also, the front top right tooth (when looking at this photo) appears to be coming in at the ever so slightest angle. Wondering, if there is something that can be done to recontour the shape of this tooth?
