I have had root canal treatment , a few hours after, i was in so much pain , it settled and went away 2 days after , i then got a temporary filling and three weeks down the line i am in complete agony , i have got an appointment to get my proper filling fitted in just over a weeks time, but the pain is unbearable . i am very frightened that when i go for my proper filling it will be agony again, please can you give me some advice, as i cant continue to take co codamol and neurofen as it makes me feel tired and doesn’t help with the pain very much.
