Hello, I'm glad to answer your question. According to your description, it is not clear what corrective surgery you had at that time and whether you had your teeth pulled out. If you don't pull out your teeth, your teeth are crowded. After correction, if the retainer is not properly worn, it is very easy to relapse. I suggest you go to a regular stomatological hospital for a follow-up visit, and choose a suitable treatment plan according to the doctor's opinions and examination results. I hope my answer can help you.
