We have to first ascertain the cause of your upper lip protrusion, before we can advice a suited treatment plan for you.
If the protrusion is due to:
1) the upper front teeth being inclined forwards,
having orthodontic treatment with uprighting of the upper incisors will help bring the upper lips back.
2) the forward positioning of the upper jaw bone,
jaw surgery might be recommended.
3) thick upper lips,
it will be beneficial to seek a consultation with a medical doctor.
To get better assessment, please visit an orthodontist for a consultation. Thank you.
