Hi, thanks for sending your question. Retainers are designed to hold the teeth in position rather than being used for movement of the teeth. You can consider orthodontics to help re position that tooth again for you. All the best!
Gingival hypertrophy/hyperplasia is a common side effect of orthodontic treatment, often resulting from less than ideal oral hygiene while the braces are on. Usually the gums return to their original size but sometimes there is residual gingival enlargement.
In these cases, you should discuss...
You may want to discuss with your orthodontist on the possibilities of a retainer correcting the protrusion which will be dependent on the amount of protrusion.
