I would listen to your dentist. If all you're needing is feelings and a root canel or two, that is far better than having your teeth extracted.
I'm 30 years old, and just had all my 11 remaining upper teeth extracted and an immediate denture placed. I don't know what happened to my teeth, it was like I woke up one morning and all my teeth were decaying. I saw two dentists who both recommended an upper denture.
It's been 18 days since they were extracted, and I wish I still had my painful, ugly, horrid, decaying, breaking teeth instead of this denture. It's not near as easy to wear as I was led to believe.
Keep the teeth God gave you as long as you can! Dentures should be your very last resort.
Good luck with your teeth,
Willy
