Had terrible toothache in upper left tooth. Pain went away after three days. X-rays-no root canal needed. Gums sore and cheek puffy. Root canal needed?

In brief: Probably

Radiographs are not a crystal ball.
.. they don't disclose everything. Did your dentist check to see if the tooth was vital (alive)? Swelling may be from a periodontal issue, so yes, in that case root canal may not be needed. More info necessary to make a proper diagnosis. Have your dentist re-examine you or refer you to an endodontist if s/he can't determine the cause of your swelling.

Just because the pain went away doesn't mean that the cause of the pain has self-healed, especially if it's from infection or fracture. Please follow Dr. Davantzis' excellent advice.

In brief: RCT needed?

The presence or absence of pain does not necessarily indicate the need for RCT.
One can require RCT on a tooth even though an x-ray does not substantiate the need. The bottom line: The need for RCT may require a number of tests, observations and history of symptoms and cannot be determined over the internet. See your own dentist or an Endodontist to determine whether or not it is indicated.
