Is a root canal really necessary?
I had a deep filling on a right lower molar 10 months ago with no issues since and really have never had tooth issues before, besides that. About 5 days ago, I noticed temperature sensitivity on that side of my mouth, which progressed over the past 48 hours to be pretty severe with both hot and cold stimuli.
So, I saw my dentist, who did the X-rays, CDCT, and exam, and did not see any structural damage, but because the cold sensitivity lingered for ~5 seconds on that same right lower molar, i'm being recommended a root canal.
I just don't understand how there could be irreversible damage to my nerve in 5 days, especially if the pain subsides after 5-10 seconds of the trigger being removed. Is it possible for transient pulpitis to self-resolve or do I really need to move forward with the root canal?
