(Concern) Dental implants for elderly people

You are someone who usually does not take good care of your body.

Recently, my mother had a dental check-up at the place she goes to for dental care.

They said I need to extract the decayed tooth and get about 3 or 4 implants.

My father said he won't do it because he's not feeling significantly uncomfortable.

Since you're over 70, your gums are also not in good condition, so getting implants is...

I wonder if it's correct.

Would it be better to just extract the teeth later and get dentures?

I'm wondering whether it's better to proceed quickly with the implant.
