I started having pain in one of my teeth on the bottom, in the back of my mouth. It got bad enough for me to see the dentist. He looks and can't see anything. There's no swelling. X rays didn't show anything either so he's thinking possibly a cracked tooth and refers me to an endodontist.
The endo tells me it's likely a nerve dying in one of my back teeth and recommends a root canal. Great. 2 words I never wanted to hear applied to me. I've never had a toothache before tho and this was pretty bad so I made the appointment. I show up for my root canal and tell him, "I think we got the wrong tooth. Number 18 seems to have pulled ahead of 19 and I think we need to reevaluate.".
So we tapped on the 2 teeth, poked at my gums and put cold q tips against them to try and figure it out. I couldn't say with any certainty which hurt worse, but he said he's 75% sure it's number 19. Well 75% isn't good enough for me so I backed out and rescheduled to see if one tooth pulled ahead of the other. Fast forward 2 weeks and I notice a bump on my gum right behind my last tooth. That bump turned into an open sore. I went back to the dentist today and just got back.
There was a bone fragment that he guessed was left over after I had my wisdom teeth out 30 some years ago and it finally worked it's way out. He picked at it and was able to flick it out with one of his tools. Instant relief! It was hurting so bad. I had pain in my neck, jaw, glands and a headache from this crap! Hot and cold sensitivity, had to chew on one side of my mouth... It went on for 3 or 4 weeks! It was awful.
Needless to say, I did not need a root canal and I sure am glad I stuck to my guns on that one!
