There was no tooth extraction during orthodontics. Now when wearing braces, the side looks more convex.

The braces themselves are thicker, so they won't be so convex when they are taken off. And it usually takes four teeth to be pulled out. If it weren't for people with many teeth and big teeth, their mouths would collapse if they pulled out four teeth. Between convex and concave, I still suggest you choose convex. It is definitely not a good thing to pull out good teeth that don't need to be pulled out for correction. I'm wearing braces, too, and I haven't had my teeth pulled out. The doctor said that my dental arch is narrow and my dental arch is enlarged. He said if I can pull it out, never pull it out. If I really need to pull it out in the future, I'll just pull it out. There's nothing to say about regret.

PS: I am a design major, and I should be able to pass the aesthetic test. I think a little awkward is much better than a flat mouth.

As for what you said about letting the teeth go in little by little, they are generally grinding their teeth, which is very harmful to enamel. For the sake of health, you still don't want it ~
