How to persuade my mother to let me correct my teeth?

If you are young and not over 20 years old, you tell your mother, "Orthodontics is the best time now, and it will add more pain in the future." Bad teeth make me feel inferior. I dare not put down my smile and communicate with others. I feel that my shortcomings have been disturbing me and I can't lift my head. I think it will affect my future life. Mom, let me have an operation! A seemingly inconspicuous small shortcoming leaves an invisible shadow in the impression of others, which will naturally make people hate. Even in the future, it will affect future job hunting. The sooner you do it, the easier it will be. If it's money, mom, you must help me find a way to operate. I promise I will honor you when I work in the future and earn more money to compensate you! More coquetry! You should not only tell your mother, but also tell your father that if you pester them to repeat this every day, they will be tempted to take you! This trick won't work, so I can only make my own money and do it myself in the future!
