I recommend H&H Dental Clinic in Singil-dong, Ansan.

I just scaled it.

It's nice that you can get medical insurance benefits once a year, so it's cheap.

My gums are on the weak side, so if I touch them wrong when scaling, they bleed and swell, so I always ask the dental hygienist to be careful before getting scaling done. But at this dental clinic, the dentist takes care of everything, so I'm really happy.
