Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain in case if you still have tenderness over the extraction site and the cheek in that area is still tender and as you already indicated that the extraction was difficult there is a high chance that some portion of root of the tooth is left accidentally in the socket and is not removed which is acting as a persistent source of infection and there can be underlying infection leading to tenderness and discomfort..
Other thing is that there can be residual infection at the extraction site and due to it there is discomfort..
You should
consult a Dentist and get an x ray of the extraction site done so that the exact cause is ruled out and treated accordingly, for infection dentist can give you broad spectrum antibiotics like
Augmentin 625 mg thrice daily and OTC painkillers like
Ibuprofen 400 mg thrice daily,while for left out root piece removal of the same followed by antibiotics will relieve..
For TMJ or TMD intake of
muscle relaxant and painkiller combination like
Flexon MR OR Nucoxia MR, warm compresses,
physiotherapy,ample of rest and taking
soft diet can be be helpful and you need to take assistance from an oral physician for proper advise and treatment..
Hope this information helps..
Thanks and regards..
