Sunken mouth due to braces - possible to restore the volume around the mouth with dermal fillers? (photos)

Hello, I had braces because of an open bite but after the teeth treatment I got slight nasobial folds and slightly sagging skin around the mouth/chin area. So I went to a doctor and had several sculptra treatments on my cheeks and now I feel that my nasobial folds have become even deeper. I wanted to ask if it is possible to restore the volume around the mouth (also the whole area between the nose and the mouth) with dermal fillers. Or if there is another possibility. Kind regards
