Stretched skin after wisdom teeth removal - At 27, what is the best solution?

Sometimes if a significant amount of bone/dentition was augmented in surgery you can unfortunately be left with a change in your facial appearance.  I would suggest to meet with a board certified plastic surgeon to determine if you could benefit from combination treatment with fillers and skin tightening modalities 

FaceTite can internally tighten the skin in the lower face and neck. After all the skin has been heated and contracted, we shape the neck with liposuction to give definition and remove stubborn pockets of fat. In one quick treatment, we can tighten skin, remove fat, and contour the lower face, jawline, and jowls with only a weekend of downtime.  Keep in mind that combination approaches will give you a more significant improvement as opposed to a single procedure. I recommend getting a consultation with a board-certified cosmetic dermatologist and facial sculpting expert. Best, Dr. Emer

A collagen stimulating filler like Sculptra could be used to thicken the skin and address volume loss. I would need to evaluate you in person to determine if you are a good candidate for this treatment.
