I am 34 yrs old. Got orthodontic treatment 2 times. Again teeth coming back to original place causing gap in teeth.

I am a lapse case of 1998-2000 so got treatment again in 2013-2015 with 2 teeth extraction from upper jaw. I am 34 years now. Permanent retainer breaks very frequently, almost after every 10 days. Got 4th tooth extracted from both sides of upper jaw. My teeth are not stable, a gap arose again in my teeth from the place of extraction. Difficulty in closing lips as upper jaw is big. Wanna beauty my smile. Can I put braces again to fill the gap? Any issues in moving teeth at this age of 34 ?
