Dnt judge. But serious question

Seriously thinking about having all my teeth pulled and getting dentures. When I was younger I had a dentist that used flamodrohyde??spelling or something of the sort that completely ruined most of my teeth. No matter how much I brush or take care of my teeth( which I'm very very clean)always brush after i eat anything. Brush 2-3 times a day besides that. But my teeth are still sooo awful. They break off all the time. And they always hurt soo bad. I'm only 23. And it's embarrassing for me to even think about but I honestly think its my best and only option at this point
