Hi,
I've been in dentistry for 30 years, primarily oral surgery. In all of that time, I have never once seen a biopsy report of any root canaled tooth that was healthy. Didn't matter if the patient was having symptoms or not, these teeth will always contain necrotic material which is bacterial and infectious.

Before you consent to root canals, please do some internet research on them. The information that explains the procedure, usually fails to state that there is no access to the microscopic canals that harbor the necrotic material. Just removing the nerve material from the central or main canals is not adequate in curing the infection due to these unattainable canals. Also....... ironic as it may be, there is no place else in the body where it is medically or scientifically acceptable to keep a dead body part. And that is exactly what a root canaled tooth becomes once the procedure is done as it literally cuts off the main blood supply rendering the tooth non viable. This is definitely something to think about if you are already dealing with a chronic health issue.

Implants may or may not be an option for you since you have RSD. Is there any way you could have these teeth removed and wear a removable appliance?
