What is this pain on my tooth on which i had a root canal? Please for any input.?

Question

Last year June, i had a root canal on an abscess tooth. I had a filling done on it, cos i couldnt afford a crown. Right now, the same tooth is hurting. It was hurting two days ago, and i took painkillers and it was fine. Today, i feel this terrible throbbing pain. I am going to the dentist in three hours, but meanwhile could somebody please tell me what is wrong.This is very troublesome for me, since i am going to travel on Monday. Please for any input. Thank you.

Superior oral health hygiene is an effective way of preventing root canal build up in the teeth that can cause infection and bleeding gums. However, superior oral hygiene such as brushing and flossing alone are not enough to stop bleeding gums nor easing away the pain. The entire mouth, the teeth and gums and including the tissues inside of the mouth should be also considered in cleaning and dental hygiene. So, what happen to that area is because of lack of oral hygiene and some plaque or bacteria get there.
