I Have Not Worn my Retainer for Quite a While? (photo)

Hello, I had a frenectomy a couple of years ago, and after that I wore braces until the middle of 2010 to bring my two front teeth together and close the huge gap. After the braces were removed, I was given a retainer to wear. The retainer made it hard for me to breathe at night. My dentist could offer no solution for this, so I stopped wearing it altogether. It's been 2 years and of course, my gap has opened back up. Will need to wear braces all over again to fix my teeth?
