I saw ㅇㅇㄷ Dental Clinic recommended on a blog, left a private comment, found out about it, and went there. To say the conclusion first, I don’t really recommend it.
I got a strong factory-like feeling, and even during treatment, I would briefly talk with the dental hygienist, then the director would come for a moment, only check what they needed for their own treatment, and leave again right away. I didn’t have any extractions, and it was a relatively small...? orthodontic treatment, but even if it was an easy case that the hospital didn’t need to pay much attention to, for me, it’s about teeth I’ll have for the rest of my life. So early in orthodontic treatment, I developed concerns about my teeth and wanted to talk even briefly, but there wasn’t really any opportunity for thatㅠ I don’t even really know the director’s face lol When I’m lying down, they come, do a quick whirring check, and leave right away again lolol
For your one and only set of teeth that you’ll keep for life, I think it would feel more reassuring to receive treatment at a hospital that pays a little more attention.
