I didn't know that a lifelong retention device is attached after orthodontic treatment.

I had orthodontic treatment in my twenties, and it took about two years to complete.

I didn't realize it just by looking, but when I took a photo, I was advised that I needed jaw surgery due to my protruding jaw. I gave up during my adolescence, but when I became an adult, I had orthodontic treatment at a hospital that would at least improve the appearance.

I'm glad it finished earlier than I thought, but I didn't know I had to wear a retainer ㅠ

I haven't been able to do it at night, so now I can't do it anymore, but it seems like I have to stick with this forever from now on ㅠㅠ

I'm a bit flustered because I started without knowing this.

Still, I'm glad just to have even teeth aligned evenly haha
