Hi, I have a rather complicated situation here. Around five weeks ago I had a root canal on a back molar (second to the back, left side - I have already had my back molar removed), two weeks after that I had a permanent crown fitted. I also had two deep fillings done at the same time (between front two teeth and upper left tooth). I have been in pain since. I initially experienced extreme sensitivity to cold and could only drink through a straw but that has now almost gone (particularly front teeth but also crowned tooth to some extent). I now keep getting random pain across the entire left side of my mouth, and the roof of my mouth, the worst pain however is in my left nostril; this pain eases when I pinch my nose. I am worried that my sinuses have been affected as my left nostril was completely numb when I had the injection in the front of my mouth and I have had pain on and off (mostly on) in my left nostril ever since - which I never have had before. I had no pain in my temporary crown, or in the temporary filling before the root canal - it has only started since the permanent crown. I don't think the bite is too high although I guess I can't be sure. Painkillers and Ibuprofen do nothing (although I haven't been taking them regularly), although when I was taking Cuprofen that worked a charm and I had no pain at all.
Strangely, I noticed that whenever I brushed my teeth or took tablets the pain would completely disappear immediately for the next ten mins or so but would come back. I have since been rinsing my mouth with cold(ish) water when I have pain and that works for a little while but I am scared it is making it worse as I seem to be getting pain more frequently now. I have tried (table) salt water rinses that eases the pain whilst the water is in my mouth but makes it worse 5-10 mins later. The only thing that really stops the pain is having water in my mouth or pinching my nose and not breathing!
I am reluctant to go back as I am not keen on my dentist (especially as all 3 fillings he did are causing me problems) and my partner had a tooth removed there just before my root canal and he ended up in A&E for 7 hours and was put on a drip as it wouldn't stop bleeding. I can't really change my dentist as I can only afford NHS and it took 8 months to get this one.
Is the pain a result of the extensive work done, and will it stop in time? Any information you can give me will be gratefully received. Sorry my question is so long but I wanted to give you as much information as possible.
Thank you for any help!
