In fact, we generally advise patients to find a doctor to complete orthodontic treatment, because each doctor's treatment plan is different, and there are many schools of orthodontics in China, so changing doctors halfway may extend the treatment time. Some doubts about you are now answered as follows: 1, tooth extraction will not cause tooth loosening, your current situation is that the teeth are too crowded, and the tooth extraction gap will be closed in the process of tooth alignment in the future, so don't worry; 2. Incision of lower anterior teeth is a common technique in clinic. Grinding off the part can prevent the "black triangle" from appearing in the gap between the lower and anterior teeth after the teeth are aligned, and will not cause gum problems. As for tooth decay, it doesn't matter as long as you brush your teeth well.

Of course, it is best if you can find the first doctor to do it.
