If you are 17 years old, you can still do orthodontics even after the best time-of course, tooth extraction is necessary. As for whether it is necessary to pull out the upper and lower parts, I reserve my opinion here because I haven't seen the symptoms yet; If the attending doctor thinks it is necessary to pull it out, it won't be a bad thing to follow the doctor's advice.

In addition, if you don't want to do orthodontics, there is a radical solution, but it is more troublesome: plastic surgery, specifically osteotomy, intercepting the upper and lower jaws to move the teeth. Needless to say, you can imagine how troublesome this method is, but it can solve the problem fundamentally.
