dentist said he can only provide a print out rather than by email, is that ok? or is he wrong?

and also i dont understand how a root canal doesnt cure the infection. And why wont an infected tooth go away on its own? the body fights infections all the time and succeeds. Why cant the body fight the infection from a tiny tooth?

It sends white blood cells to fight it and then clears it up. yes it could reoccur but if it does then the body fights it again.

i had a blood test recently and it didnt show anything unusual. Any serious infection which would harm your health would show up on the blood test no?
