Should I Remove My Dentures To Get Facet Block For Occipital Nerve Headaches?

I may have to get a facet block for occipital nerve headeaches. my doctor said it would be x-ray guided. procedure done in office I will be awake. he said he would x-ray just the spots where he is inserting needle. does this mean he will not be x-raying my entire head. I have dentures no metal will I have to remove for procedure. I am very self conscience .
