A dentist may legally prescribe any analgesic, narcotic or not, if it
does not conflict with state law and the dentist is registered to give
it by the DEA.  Of course, a dentist who routinely writes prescriptions
for fentanyl for dental pain is going to get into trouble somewhere.
    You should know that effectiveness of a given analgesic vary from
patient to patient and from time to time in the same patient.  You also
want to look at the potential side effects of these meds when
prescribing, and of course the patient's health.

What is the most powerful pain killer that a dentist can legally
prescribe for a client to take after a root canal?

    It is sometimes impossible to numb a "hot" tooth.  Injecting into a
pulp in this condition is not fun.  I presume the endodontist placed a
fixative agent in the pulp chamber, which should kill remaining vital
nerve tissue.  If it does its job, next time should be much easier.

My endodentist attempted a root canal on a lower back molar today. I
have undergone 2 root canals with the same doctor before and had zero
discomfort.
Today she gave me 2 injections which numbed my mouth very well. Once
she was inside the tooth I experienced pain. She then injected inside
the tooth (excruciating 2 seconds of pain). She drilled some more and
all was ok, then she inserted the first file, and I FLEW up in the air.
The pain was beyond belief. I had tears streaming down my face and
could not believe this could happen to me. She then packed the tooth
and filled it, and said when I go back next week the nerve should be
virtually dead and she will continue.
I do not think I have the inner strength to attempt it again.
What is happening and how can I continue?
