Orthodontics mainly depends on the condition of the teeth themselves. Orthodontics is not limited by age. I have a colleague who is almost 35 years old. She is also doing invisible orthodontics in Dr. Riel Yansha Xie Rainbow's clinic. According to her introduction, Dr. Xie has been engaged in oral clinical treatment for 20 years and is a member of the Chinese Stomatological Association. He is good at invisible orthodontics and fixed orthodontics for adults and children, treats people sincerely and enthusiastically, and treats customers as family, which is really in place ~
