Undergraduate, master and doctor are different, of course, the effect of orthodontics is also different. Although the price is a little expensive, it is guaranteed and people are responsible. One of my classmates went to a small clinic to correct his teeth when he was a freshman. At first, she thought the price in the clinic was cheaper, and then she was recommended. After she went, she directly regretted it. Her teeth are not well corrected, but they are even uglier than those without correction. Now the doctors in that clinic are a little impatient when they see her.
Every dentist's experience and educational background are different, and the effect of natural orthodontics is also different. Try to choose regular hospitals when going to orthodontics, and carefully consider those dental clinics.
