Hello there!
If your root canal treatment is completed without complications, then you will not require a dental implant. The aim of a root canal treatment is to retain your own tooth. A dental implant is to replace a missing or extracted tooth.
How long should I wait?
After a root canal treatment, a crown is usually advised to protect the tooth from reinfection or fracturing. The crowning process can be started on the day of root canal treatment completion, or a few weeks after. Hope this helps!
