After root canal therapy, why is a crown or permanent restoration usually necessary?
Show answer and explanation
Correct answer: Because the tooth becomes more fragile and needs protection
With pulp removed, the tooth loses internal structural support and becomes more brittle, so a crown or permanent restoration is necessary to protect it from fracture. It does not restore nerve tissue.
