I know I'm kinda over reacting but I can't help it right now.
I had a root canal & crown on a molar over 5 years ago with a dentist I had found randomly. While under her care I also got braces. During my ortho treatment the tooth that had the root canal snapped - it turned out that the dentist did a HORRIBLE job with the crown and it wasn't stable enough for braces. My orthodontist was horrified and referred me to a new dentist (who rocks). The new dentist stabilized my tooth and crown.
Fast Forward to today. I had a cleaning a few weeks ago - my dentist always checks my teeth after every cleaning. He noticed some swelling - gave me antibiotics and referred me to a specialist. I go to the specialist today - she does an x-ray then tells me that I have massive issues with that tooth. She says that the original dentist did not complete the root canal properly and I have developed a bad infection. The root canal has to be re-done. Cont.
