Why saving your own tooth comes first
A natural tooth has a root, a ligament, and a blood supply that no implant can fully reproduce, so the most conservative path is almost always to keep the tooth you already have. The evidence backs this up: a systematic review found no significant difference in long-term survival between a compromised natural tooth restored with root canal treatment and a crown and a single-tooth implant, which means a well-treated natural tooth can do just as well as a replacement.

This holds even for teeth that look heavily worn down. Periodontally compromised molars, with proper treatment and ongoing maintenance, kept a pooled survival of 82% over a mean of about 15 years, fewer than one molar lost per decade. [2] Dr. Khalid reads your case with this conservative lens first, so an implant is discussed only once keeping the tooth is genuinely no longer sensible.
