The landlord should correct it as soon as possible. People older than you have done a lot of orthodontics. If buck teeth are corrected, teeth should be extracted, and the landlord should be fully prepared before correction. By the way, I am also correcting it, but the situation is different from that of the landlord. I have a friend in the same situation as you. Her mouth sticks out forward and her gums are exposed when she smiles. Now that she has corrected it, she looks much better.
