However, the process of correction will be a little longer than that of children. According to your description, I think you should go to a dentist in a regular hospital for face-to-face consultation and oral CT, so that the doctor can see what is the cause of your crowded teeth and then listen to his professional advice.
If you really need correction, you don't have to have surgery, you must decide according to your personal situation. If there is no gum problem, then it will be fine without surgical correction. Although the orthodontic recovery of adults is not as fast as that of children, it will become more and more difficult if it is not corrected now. Many people unilaterally believe that 18 years old after the teeth are fixed, can not be corrected. In fact, this is a wrong understanding. Missing the best age for orthodontics doesn't mean that you can't correct your teeth. The sooner you correct it, the better. Otherwise, the difficulty, time and cost of orthodontics will increase with age. It should be noted that the cost and recovery ability of adult orthodontics are not as good as that of teenagers or children, and the requirements for doctors' experience are relatively high. We must find a reliable stomatological hospital for treatment.
