Have you considered the possibility that the dentist implanted a tracking device into your teeth hence the pain! Do you set off alarms in shops? Can you pick up the local radio station in your head? On a serious note from what you've said so far it seems that you are at the initial stages of a mental breakdown, what you are talking about is the ramblings of a troubled mind. I suggest you ask your doctor for an anti-psychotic drug which will reduce your visions of the future 10 fold. P.S. - Change your dentist, and I hope the pain subsides for you soon.
