In order to decide which method would most effective, we would need to assess and treat the cause of the protrusion.
If it is due to protruding upper teeth which are flaring out and causing the lip to come forward, braces or Invisalign treatment would be ideal to reduce the protrusion. There may be a possibility that extractions of some teeth may be required to provide some space for the upper front teeth to move back into.
Sometimes, it may be due to the imbalance of the upper and lower jaws. If it is due to the upper jaw being too forward, orthodontic treatment alone would have its limitations and jaw surgery to set back the upper jaw may be a better option to achieve the best result.
It would be best to consult an orthodontist, who can then refer you an oral maxillofacial surgeon if moving the teeth alone will not be enough to reduce the protrusion of the upper lip fully. Rhinoplasty and chin augmentation would be considered more as adjunct or supplementary treatments.
If the upper lip protrusion is due to excessive soft tissue, you will need the expertise and advice of the plastic surgeons or aesthetic doctors.
Hope this helps. All the best.
