First of all, I suggest that you wait until you enter the university to do orthodontics, because there is no difference between 17 years old and 18 years old. And the study in senior three is very tense, so review your lessons well.

According to your description, it is better to treat protrusion or crowded incisors or to choose tooth extraction, because orthodontics is only done once, but it will determine the beauty and health of teeth in the future, and the curative effect cannot be wasted because of time.

If you don't do orthodontics now, you can pull out your wisdom teeth, but don't pull out other teeth needed for orthodontics, because if you go to college, this doctor can't do orthodontics for you, and he will redesign the orthodontic plan for other doctors, because orthodontics is the responsibility of the first visit, and whoever makes the treatment plan will be responsible for the curative effect.

Even the tooth extraction is only 1.5~2 years, and the treatment will end when you are a sophomore, which will not affect your job search and mate selection.

I hope my suggestion can help you. If you can come to Tianjin to go to college, you are welcome to come to me.
