(Concern) Number of implants

My mother is now around 70 years old, and I think she needs to get implants.

Currently, your upper teeth are almost missing, and you are wearing dentures. In this case, do all the upper teeth need to be replaced with implants?

Or do you only do a few and then use dentures on top of them?

I'm so sorry to see how your teeth ended up in that condition.

I'm worried that if I have to get all my upper teeth replaced with implants, it might be too painful.
