Hello, your problem is not very serious. It should be said that fifteen years old is the best time for orthodontic treatment (correction), because your alveolar bone is not fully developed and the treatment time is shorter than that of adults. Treatment only requires wearing an appliance, and no surgical treatment is needed. Total treatment time * * * 1 year and a half to two years, including correction and maintenance. Of course, I suggest you go to a regular stomatological hospital for examination, and the final diagnosis and treatment plan still needs to be formulated by a doctor.
I hope you get well soon!
