<human>: So here's the story:

I recently went in for my yearly dental checkup. I have a recurring issue with a flap of skin becoming inflamed behind my right second molar. This has happened periodically ever since my wisdom teeth were removed (about 9 years ago). It lasts a few days and then clears up. 

Well, when I went in this time around, it was inflamed, prompting the doctor to refer me to an oral surgeon, who poked at it, physically ripped the inflammation off, and told me I would need to have the area behind my tooth cleaned out, and, depending on the condition of the root, have the tooth removed. 

I'm a bit skeptical of this. The doctors entire grounds for sending me to the surgeon was a set of X-rays showing a shadow that he freely admitted could be anything. The surgeon barely glanced at the X-rays before telling me I needed a procedure done. When I called the dentist back, they were convinced that I needed to have the tooth removed entirely, and warned me they might have to cancel my appointment and send me back to the surgeon.

From my perspective, this 'issue' has existed for nine years, has never caused me any discomfort, pain, or inconvenience, and my tooth shows absolutely no signs of being loose, infected, or otherwise out of the ordinary. I'm going back on monday, but I intend to request a second set of X-rays, since I'm not convinced this issue actually is anything of the sort.

Am I in the right asking for a reassessment here? I'm 22, and in perfect health. Removing a molar because it's not bothering me seems a might excessive. To cap it all off, ever since the surgeon removed the inflamed tissue, the inflammation has gone away, and has not returned.

Can you condense the text into a few key points?
<bot>: Doctor sends me to surgeon, surgeon tells me I might need a root canal, all over a spot of loose tissue that has existed for nine years and has never bothered me.
