retreatment of a root canal or not??

kennn

Recently I started having a dull biting pain in my rear teeth #3. Best described as very tender to biting which initiated the dull pain. This tooth had previously been treated with a root canal and crown. Dentist x-rayed and said she didn't see anything and said that it was likely a root that had not been originally identified and is now causing the condition. She made an appointment with an orthodontist ( 3 weeks later) and sent me on my way without any antibiotics. Said options would be retreatment or an implant. A day or two latter the tooth has quit hurting, no sensitivity or pain at all. If there was an issue (abscess) wouldn't that have been observed by the xray. I concerned that someone may want to do considerable work for something that may not be an issue at all. How can I verify.
Thanks your your comments in advance.

an abscess can take a few days to show up on an x-ray, as there needs to be a change in the bony support underneath.
antibiotics would only be prescribed in acute pain, and in another thread i think davo10 said that he knows one endodontist that doesn't prescribe antibiotics at all, so each have their own protocol.
as for the problem with the tooth, sounds like the 2nd canal in one of the roots has started acting up. i'm not a fan of endo, and have only seen that canal once. that was in college.
over to you res.:)

maxillary sinusitis is a possibility. basically a bad head cold that feels like a toothache. did you have anything like that around the same time?
