I'm looking for a dentist in Incheon, but I'm already scared.

Three of my teeth got worse while I hadn't been to the dentist.
They say one has a broken root, and it is difficult to save the other two as well.
The thought of having to do three things at once makes me feel completely lost.
I can't even chew my food properly, so I'm having trouble digesting it.
I never thought I'd be worrying about this at this age.
Those of you who had dental implants in Incheon, please help me.
