At present, the orthodontic technique is to wear a steel wire. As for whether to have a tooth extracted, it depends on your personal situation. First, you have to take a dental film, and then according to the film and the structure of your teeth poured out by the grinding tool, you can determine whether to extract teeth and correct the position.
The price I made at that time was more than 7000 yuan, and I didn't pull out a tooth, probably because I was stupid and didn't have wisdom teeth, so I didn't have to pull it out, hehe. Some people have pulled out all four teeth on the side.
Most of the whole process takes two and a half years. I used it for two years, so I didn't need to put it on for that long because I didn't need to pull out my teeth, and I didn't use a rubber band to fix it later. It is said that after tooth extraction, the steel wire will be fixed in the mouth with a rubber band for half a year after it is taken out later. I mean, as long as the steel wire is removed and finished, it will take less than half a year. During the rectification period, you need to go to the attending doctor to adjust the steel wire every one to two months after you start putting out the steel wire. Usually, you have to go to the attending doctor when the steel wire falls or breaks, so it is more convenient to have more free time and find a hospital near home or work.
