Is it possible that my Dentist caused my tooth to become abscessed when he replaced an old crown?

I developed a gum boil shortly thereafter. I have had a root canal in the tooth for ten years. If it is likely his actions that caused it, what course can I take to get him to take responsibility for treatment since I do not have dental insurance?

It is very unlikely that your dentist did anything in replaceing the crown that would have caused an infection. Why did you have to have the crown replaced? sometimes people get decay around the crown and that can cause an infection. If the decay occures below the gumline the dentist cant always see it. Also, its possible that you cracked the tooth under the crown. That is always an issue with rootcanaled teeth and it can happen when the temp crown is on. When that happens it can allow bacteria down into the root so that it can cause infection. But, main point here, is that baring the dentist doing something terrible, you getting an infection is an unfortunate situation but not something that he/she would be responsible for. You can see if they will give you some antibiotics and it might clear up. Also, i dont know if you are a female, but they have found that women are often more sensitive to metals in their mouth, so maybe if your crown has metal under it, it could be causeing some of the problem.
