[Orthodontics] Calibration 1n year review

I got it straightened when I was young and now its really good, but it was a case in which the teeth on either side of the front door went behind the lower teeth. Everyone said that we need to secure space, so why do foreign doctors want to extract raw teeth? Even now, its aesthetically pretty enough, dont extract your raw teeth. Well, its been 1n years now, but I want to do really well. To be honest, its been ten years and its been a long time since I lost my braces?? Even though I didnt take good care of it, it didnt change much because I didnt extract the teeth. The spacing between the teeth isnt terrifying. Each doctor has a different opinion. ~!~!
