Not likely. If the root canal therapy is successful and you then protect the tooth with a crown or whatever other restoration your dentist feels is appropriate, the tooth can last forever and not need a replacement. We see this all the time. However, if the rct fails, or develops periodontal problems, an implant supported tooth is usually the best replacement option. Discuss your options with your dentist.
Choose only one! A damaged nerve may be treated with only 2 options. A root canal to remove the damaged tissue or an extraction to remove the damaged tissue and the tooth housing it. If the tooth is removed, the newly created space may be restored with an implant. The best treatment option depends on the circumstances necessitating the treatment.
