(Concern) I'm 고민ing about dental filling materials.

Recently, while eating hard food, I felt a sharp, stabbing sensation as if my brain was being pierced, and I thought, oh, this must be a cavity!

So, I ran straight to the dentist's office right in front of my house.

As expected, it is said that a cavity has formed in the upper molar.

I'm concerned about the ingredients and the price difference.

Materials covered by insurance are said to cost up to 20,000 won each, and they need to be replaced after a few years.

The resin costs around 100,000 won per piece or more, and it is said to last a long time.

Which one should I choose?
