It hurts at first, especially in the first week or two, when the teeth are slightly in contact. This is because the teeth are under unprecedented pressure, but it doesn't matter, just get used to it. Then I have to check it once a month, and I have to press my teeth again every month, and it will hurt for a day or two in the future.
Correction needs to find a place close to oneself, and of course it also needs a good hospital. Because I go to the hospital every month. Also, the alveolar bone is easy to fall off at first, and it should be glued back in time as soon as it falls off (alveolar bone and teeth stick together). It is very likely that you will post this today and drop that tomorrow. You are from Xianyang. Do you have to come to Xi all day? I think Xianyang also has good hospitals.
In addition, the cost of hospital correction is relatively high, which is more than 6000 in the above hospitals. Depending on the complexity of the teeth.
I come from Xi 'an. Just finished correcting, now wearing braces. After correction, I will wear a retainer of 1.5 years and keep the correction results. My situation is similar to yours, except that my front teeth are irregular and skewed, which has been corrected now. I didn't pull out my tooth. I was made by a doctor in the Fourth Medical University.
You can search online for information about orthodontics and have a good look. Reduce your worries.
