Any good clinic is possible. The problem with braces is that the teeth themselves are defective or have a lot of cavities. In order to prevent teeth from cracking after restoration, braces are needed to supplement the functions of teeth, such as steel crowns and porcelain crowns. If there is no defect but a small cavity, it can be repaired, or if there is a root canal problem, the root canal should be treated first and then repaired. If it's complicated, it's better to go to the hospital.
