Correction usually takes about two years, unless the difficulty is small and the treatment response is particularly good, it can be ended early. Many people are most concerned about uneven teeth, which is the easiest and earliest solution for orthodontists. Therefore, many patients see that the problem they are most looking forward to solving has been solved, and they are eager to end the treatment. In fact, alignment is only the first stage of treatment, and it is necessary to close the gap and adjust the occlusion. These treatments have no obvious changes on the surface, but they will take up most of the treatment time, so don't worry. Correction is a kind of treatment against natural forces, which requires a step-by-step process and enough time to make the effect of treatment stable. So don't worry, it's important to cooperate well according to the doctor's requirements.
