I don't know if you are talking about orthodontics, that is, the kind with brackets and steel wires. If it is, if it is not done well, it will affect the occlusal relationship of the whole mouth and there will be many problems. It is recommended to go to a regular professional hospital. There is also a cosmetic crown, which is also a hidden danger if it is not done well. There will be no problems with teeth in the near future, but problems will occur in 1-2 years or 3-5 years.
