Are there any good dental clinics near Bupyeong Market Station?

Two of my lower right molars have been loose for a while now, so I think I'll need to get implants...
I looked it up online, and things like bone grafting are so complicated.
And why is the price so expensive?
Is there a good place near Bupyeong Market that serves good food without being overpriced?

It would be nice if the price were affordable, but it’s probably not easy for implants to be cheap, right?
Oh dear, as I get older, I really have so many worries.
