I recommend Seoul Bon Dental Clinic in Jongno-gu.

I recommend Seoul Bon Dental Clinic, located in the basement of the Space Bon apartment complex, rather than a large, fancy building in the city center. Because it's a local dental clinic, they're friendly and don't force you to get unnecessary, non-covered treatments. They explained my dental condition thoroughly and recommended only the necessary treatments, which was nice. I was shocked when I went to a large dental clinic in Jongno 1-ga. They didn't even look at the cavity I had, and recommended a million won worth of resin treatment. I'm so impressed by these neighborhood dental clinics. I regularly go for scaling and cleanings, and they're a trustworthy dentist.
