It depends on my personal situation. My teeth are convex and a little irregular. I didn't pull out my tooth. I had Invisalign correction and spent 47,000 yuan. This price is neither high nor low in Beijing, but the doctor who corrected it for me is more experienced. I have been wearing braces for almost 7 months now, and my front teeth have changed a lot. After the final correction, I should be almost the same as this sister, because my teeth are more like her.
