There is no reason to replace root canal treated-teeth with implants unless there is pain, infection, swelling or a fracture of the tooth.
Even when there are issues with root canal treatment, redoing the root canal treatment may still be an option if the tooth is still restorable.
A natural tooth preserves bone and gum tissue volume in a way that cannot be replicated by implants yet. Complications and the costs associated with maintaining a root canal treated-tooth are still easier to manage and cost less compared to implants.
All dental treatments have a lifespan, root canal treatment or implants are no exception.
