When a person gets a root canal is it common practice for a general dentistry dentist to treat both canals if the tooth has two roots as in the case of the #5 tooth? I was seen by a dentist who put a crown on my #5 tooth. He did a root canal prior to the crown being placed on it. From the time he did it until now 5 months later I have been complaining that it hurts, that something is just not right with it. He took another xray and said there was nothing wrong. The last 3 times in his office he did this. I finally went to another dentist who said that only one root had the root canal and I had an abscess at the end of the other root which was not treated. Now I will have to pay a specialist $500 for something that I think was done incorrectly the first time. My new dentist and the Endodontist doesn't understand why my original dentist only did one root? Did my first dentist do something wrong? thank you for your time I appreciate it.
