Just go and get the denture done. It's cheap and it serve the purpose.
2 to 3 times appointment should get the whole thing fix and you are ready to move on. For root canal and crowing, it depends on many factors. The skill set of the doctors, multiple appointments got to be schedule. It waste the time to earn precious money. Plus the pain and physical ordeal ones has to go through.
It really not worth the effort and time.
