Molar tooth..

My molar is throbbing, but I wonder if it's just my imagination.

Even if I drink cold water, it touches the gold and feels cold, but it doesn't hurt like nerve pain.

It's a place that was filled with gold, but when I come back feeling sick next time, I was told I need to switch to an implant for treatment.ㅜㅜ

How much does the implant cost?

I'm worried about calculating the money in advance for no reason~
