haven't been following along but would like to add when it comes to extensive work get multiple opinions...i have been put threw thre ringer ...i have even been told the day of my root canal "oh it's not this tooth, it's the one on the left"..

how the F do you get them mixed up...excuse me....i am in now constant pain from bridge work that was done years ago extractions were done and surgery and i was on soo many narcotics for 2 weeks even waking up at night in pain. Now i think it's a nerve that he hit that is causing my face pain.
My enamel is soft and at times it feels like i have nothing but cavities in my mouth i have to go every 6 months because my teeth are just really bad...but most of the time it's my root nerve that is exposed from my gumline that makes me think i have a cavity when i dont (even though every tooth in my mouth has been worked on)
6 months ago a molar was hurting and the guy said i needed a root canal (my 6th one) and i scheduled it and everything...didn't go ...my tooth doesn't hurt anymore....who knows...always get opinions many of them
