Most patients find that modern root canal therapy feels no more uncomfortable than having a cavity filled. Local anesthesia helps keep the procedure comfortable.

Most procedures take between 60 and 90 minutes. Complex cases may require additional visits.

In some situations, retreatment may be necessary if a new infection develops or the restoration becomes damaged.

Saving the natural tooth is often preferred when possible because it maintains jaw support, chewing function, and alignment.

With proper restoration and regular dental care, many treated teeth remain functional for decades.
