Correction can't be done by two doctors, each doctor has his own design scheme, and two people can't cooperate as well as one person, which often gets twice the result with half the effort. You must choose a good doctor, just one. Correction takes several weeks, and the doctor will adjust the treatment plan and method in time according to your situation, and increase or decrease some orthodontic facilities. So it will be more convenient to choose a city where you live most often, and I feel it is more convenient to live at home than at school. For an adult, it is normal to have orthodontics for 2-4 years, and it is necessary to persevere. It is not only beautiful, but also beneficial to health to have a neat and well-bitten tooth. Now the cost of regular provincial hospitals will not be less than 6000. However, it is still worth doing.
