Teeth are starting to stick out, was wondering if there were any options to correct problem without braces? (Photos)

One clear aligner will only keep your teeth from getting any worse. You may need a short treatment with Invisalign or something similar to actually change them back to where they were when the braces came off. I would suggest going back to your orthodontist, or another orthodontic specialist if you prefer, and just fess up and say you didn't wear your retainer and now you have learned your lesson and want them straight again. Then, after you get them where you want them, learn from your experience and wear your retainer like you are instructed. Good Luck!!

I would suggest you see your orthodontist. He can make a removable appliance that can move your teeth back into position. This is called a Hawley appliance. The catch is you have to be more diligent in wearing it or they will relapse again.
