"Ok so i had a root canal 4 years ago that failed and ever since that i had a phobia of going back to the dentist. The infected root canal was the worst pain i ever had in my life. I eventually got the tooth extracted and was pain free again. Anyway, know i have this one tooth that has been hurting me on and off. Sometimes it doesn't hurt for a couple days and then pain comes back and goes away again. Their is also sensitivity to cold and hot drinks. Could it be time to go see the dentists again? i really don't want another root canal im thinking just an extraction because i don't want to go thru that again. Im a little worried know i might have waited too long with the pain since this tooth has been bothering for almost 3 years know but it wasn't serious enough to seek immediate dental care.  What do you think?"
