Implant cost

I had no idea since I live separately, but I found out that my mom was wearing dentures.

I looked and was told that I almost have no upper teeth and need implants, and they are talking about around 20 million won.

They are planning to do about two first, but is it usually this expensive?

If you need to budget around 10 million won per unit and plan to do multiple, it seems like the foundation of the pillar might be uprooted. Is there an appropriate or reasonable cost range for implants?

Or is it worth what you call it?
