Actually, it won't be a pity! It is not too much for a girl to pay a little price for beauty. And I don't think it will have much impact on the function of teeth! I am also a 13-year-old girl who is about to have her teeth straightened. I had these doubts before, but I asked the doctor, and the doctor said it doesn't matter, don't worry too much! May your daughter have a row of neat teeth after correction! ! !
