It is recommended to take a photo in a regular hospital, because the tooth structure is different, the manufacturing process is different and the cost is different. On the whole, my teeth are quite powerful. I was 20 when I got it last year. The doctor said about 2 to 2.5 years, and my classmate also has a lighter one, about 2 years. In fact, some beauty hospitals say that adult teeth can be fixed without pain, and seven days is enough. That must be very unhealthy for your teeth. Well, that's almost enough. In fact, if your girlfriend is just a little violent, there is no need to do so. After all, it's painful and it costs money. And I have to go to the hospital for a follow-up visit every month. I don't think it's worth it I don't think you care about having such a good boyfriend. By the way, I got it in Jinan, where there are more than 7 thousand, 7 thousand to 10 thousand, and the situation is different from place to place
