I would like a second opinion about the dental treatment recommended to me and the care I received. Last year, I went to a dentist because I had an abscessed tooth. I was given amoxicillin to take for 1 week, then I received a root canal. The amoxicillin didn't cure the infection, but I was told the root canal would get rid of the infection. A couple of months after the root canal, I received a permanent dental crown. The dentist did not do an x-ray before placing the permanent crown to see if the root canal had removed the infection. The crown was also poorly fitted. I had it adjusted twice, but it still uncomfortable and made my gums more inflamed. I requested for the crown to be removed and get a new crown. I was told that the infection is still there and that I need a root canal retreatment before I can get a new crown. I spoke with a family friend who is a dentist and was told that I was not given proper care. I was told that after I took the amoxicillin, the dentist should have placed an antibiotic into the tooth to remove the infection. I was told that the dentist should have done an x-ray to determine if the antibiotic was working before doing the root canal procedure. I was also told that the dentist should have made sure that the infection was completely cured before placing the permanent crown. I was also told that taking another round of amoxicillin and placing an antibiotic into the infected tooth could still cure the infection and that I may not need the root canal retreatment. Is this information correct? Did I receive improper care? If so, what recourse do I have for the poor treatment I received?
