Radio-opacity on x-ray

I recently changed dentists after 15 years with the same Dr.  Over this time, I've had regular cleanings/exams and only 1 new filling necessary.

My new dentist immediately recommended replacing a filling, which I didn't question since my fillings are about 40 yrs. old.  After that, he called me back and asked to do another set of x-rays which were done today.  I've been referred to an oral surgeon to check the radio-opacity of #32 area, which I understand to be the location of a wisdom tooth that was removed about 22 years ago.  

My insurance will not cover another dental exam. I've had no physical problems with this area, and my previous dentist never mentioned any concerns with it. I'm suspicious and tempted to ignore his advice and go to a different dentist (or back to my old one) for my next cleaning in September...

Thoughts/Advice?

A radio-opacity could be indicative of many situations, some very benign and harmless, others requiring treatment.   If detected it is best to follow up with the recommended referral.  It is always best to err on the side of caution.
