Sounds a right saga...had two out with the NHS the last couple of years, pretty quick and painless and lucky to even get an NHS dentist apparently.
They said both teeth could have been saved but not being a millionaire, I declined.

need two or three out..my body reacted to UV amalgam setting rays over 25 years ago and my fluoride damage is historical, extensive & hideous...bad teeth started to fall out..they've nearly poisoned me to death more than once..so ill with various conditions Nov 2025 on that I have needed blood-pressure monitoring....good news though I've found a herbal they gets me straight... more than well enough to get the rest of the weight off (although I'm under max for my height) I swim two sets of 2,500m/week most weeks..I've had bad-teeth, flu, bad-teeth, heavy cold, bad teeth for the last six months..a mix of dihydrocodiene, booze and other stimulants was a car-crash of an occasion I can happily blame on pain and illness, nevertheless, I've had to clean up the mess..
