It is not easy to lose your teeth when you are old. Don't worry! You 19 years old. I suggest you correct it as soon as possible! The older you get, the longer it takes to correct, and the longer it takes to wear the retainer in the future than ordinary people. Landlord, although you have passed the best time to correct it, it is still effective. According to what you said (a little bit buck teeth, a little oblique arrangement), you may have to have your teeth pulled out. I suggest you do it in a regular hospital! It's safer this way As for the price, the metal bracket in Hangzhou is 3500 in half and 5000 in full. Of course, there is something better, that is Toto, but that price is much more expensive. Maybe different third parties will have different prices!
