My son il is and fil was a dentist. Root canal and crown saves the structure of the tooth, the preferred approach. The alternative, extraction and implant is a more expensive and less optimal approach. I once had a bad tooth that had root canal and I continued to suffer, the root canal was repeated, at no cost. Eventually a fracture of one of the roots was discovered leading to an extraction. The oral surgeon suggested watchful waiting before any implant. It was a moose so not seen. I still have the empty space.
Good luck.
