Has anyone here had all their teeth extracted and gotten dentures instead of implants?

I did that in my early 40s after years of dental issues. I had the same dental surgeon since I was a kid and to this day swear he was the only dentist that was always honest with me.
My gum tissue never adhered to my teeth enamel so most of my difficulty began below the gum line.
Except for root canals every dentist I saw lied to me about restoring my with very expensive procedures as you said. I wasted money on work, caps and bridges that all failed. I went through two sets of partials and was fed up.
I had touth bothering me so bad I sad screw the dentists, I had seen several, and went straight to my surgeon to have it pulled. While there he told me he was retiring in a year. There and then we had a talk about all i'd been through and what could be done. He was honest about the potential of saving what I had left so we made a plan for full extraction and dentures. The post mounted dentures didn't exist then.
It's a big transition. The days of tooth pain are over but eating with dentures is a new challenge and can have their own on and off discomfort. I'm told the post mounted can reduce those problems but I have an aquantance who had bone deterioration around the post. And those are far more expensive than dentures.
It's a tough decision but I wouldn't go back to those days of constant tooth pain. Some of us are just born with bad gum and tooth structure that constantly brushing and flossing won't help.

I had a similar predicament and consulted multiple dentists. Seems dentures are not the ultimate solution and has problems later as well. In contrast implants provide a lasting solution, though costlier.

Uprootinnof tooth and getting implants should bebdelayed a smuch as possible. Replace crowns if needed. Will help defer the implant. Get regular check ups and increase oral hygiene. Salt water gargling and correct toothpaste helps. Also intradental brushing and flossing and regular descaling.

I have dentures full upper and lower.
They are a pain in the ass and expensive.
I paid $8,000 US for 26 extractions, 5 root canals, and two sets of uppers and lowers.
About once a year I have to have them resized.
They get sloppy and cause your gums and checks to get sore.
I get the home kit that's $20 now but when I had them do it, which is better, it's about $250.
Implants are about twice as expensive.
I would say save as many of your teeth as you can now and get partials.

I suggest getting opinions from a couple more dentists. Dentures are no fun from my observations of people that have them.

Like a couple others have suggested -
Sometimes dentists are not always honest about things.
They will try to sell you a bunch of unnecessary work. Especially these corporate dental chains.

I very much doubt your natural teeth are so bad that they all need pulled.

But yeah unfortunately, some doctors and dentists are crooks. Do not take any drastic steps until you TRULY know your options instead of just from one dentist trying to make a buck.
