Going to the dentist and having the internet go out ,that happened to me,,, seems I have a tooth that is dead yea they did the cold water test I didn't feel anything they did the Ol three stooges test where they hit the teeth till they get to the dull thonk ,I heard the difference this was two years ago,, only problem I don't have any problems with it ,doesn't hurt me I chew normal with it but they say I need a root canal and crown 2200.00 worth ,,, so two months ago I made the decision ,my insurance doesn't cover it anyway I was gonna do it so I get there and they start prepping me but the WiFi had been out,,so they couldn't get to my files or xrays they weren't sure what tooth they were supposed to work on so finally they came and asked me , and I tell them it was number 12 which is next to the incizicer on top,but they weren't confident with that so they made the decision to postpone the procedure,,that also made up my mind,I'm not getting it done ,,,,
