My Frount Tooth Has Shifted Due to Gum Problems, Can This Tooth Be Fixed

I think that the first thing you should do is consult with a periodontist.  This is a dentist that specialized in patients with gum and bone problems.  Let them figure out the cause of your bone loss and treatment for it, then you can have a restorative dentist look at correcting any aesthetic issues. Good luck.  

I would suggest you be evaluated by a periodontist(Gum doctor) and a cosmetic dentist.
They will evaluate if you have enough bone support to keep that tooth and if tooth is strong enough to have orthodontics or possible veneers to correct your problem.
They will present to you the treatment alternatives and the cost to improve your simile.

First, my question is has the gum problem been addressed?  Is there still gum disease going on?  If there is, then any treatment will only be a temporary fix, as unstable gum/bone issues will eventually cause the tooth to move more and more than likely eventually be lost.  Thus, I recommend solving the gum disease first, AND THEN solving the tooth shifting problem.The treatments that you might be a candidate for are orthodontics, veneering, crowning, extraction and bridge or implant, to name a few.  Go to a good dentist, possibly a periodontist to treat your gum disease, and then see what he/she recommends.Good luck!
