As I can c , u got ur braces done wn u wre 20 yrs old, little late , so the chance of relapse ( teeth again coming out ) is more ,

pls consult an orthodontist , ( specialist in braces ) , for ur age after the treatment is complete , they do give something called permanent retention ( placing a wire from inside ) which will b n place for an yr or so , which prevents relapse
