Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain in case if you have pain in jaw extending from chin upto the ear and
pain in teeth and as pain is more specific to your capped tooth there is a possibility that there is infection in the capped tooth or the tooth is fractured..
Secondly pain in upper jaw and cheek can be due to
sinus infection and is not due to lower tooth that is capped..
Such kind of pain can also be due to nerve related pain but as you have
swollen lymph nodes chances of infection are more probable..
Swollen lymph nodes under the jaw can occur very much due to
tooth infection and it is one of the commonest cause and it is not true that it cannot be due to the tooth..
Therefore I would suggest you to consult an Endodontist and get evaluated and in case if there is infection in tooth removal of the cap followed by
root canal treatment and replacing the cap can help..
As of now you can take Ketorolac or Tramadol to relieve pain..
Hope this information helps..
Thanks and regards.
