Hello Mark. I had a root canal treatment over a series of 3 appointments, as I was told that the tooth was inflamed & difficult to numb the area properly. I was in a lot of pain after with the temporary filling, which felt very bulky. I explained this & my dentist put the permanent filling in & gave me antibiotics in case of infection. The pain has settled but is still there intermittently and I was hooked on Nurofen for an entire week after. The pain now feels as if in it’s in my jaw & face & comes back after eating. I am a grinder & so it maybe this? I got a 2nd opinion last week & this dentist took X-rays & checked my jaw movement – he says the tooth is fine & likely to be jaw muscle damage & that I need a soft bite guard or maybe try physio & get referred by my original dentist. When the pain comes, it’s pretty bad – does this sound like an accurate diagnosis? It sounds feasible from what I have read, but am still worried & taking pain killers so much can’t be good long term. Thanks for your help.
