Dentistry in a big hospital is much more expensive than that in a dentist's office, and the technology is not necessarily better. It is recommended to do it outside the dentist's office. Now the price of orthodontics seems to have increased by 4000 yuan, compared with 3000 yuan last year. Sure, you can make a counter-offer. You can go to Zhang Laiyou Stomatology (near Anyi University) for orthodontics. His family is not bad, and he is more responsible.
