I am a 40-year-old female and have a mass on my jaw bone, on the lower left hand side, in the middle of the jaw, apporoximately 1cm.  The mass is solid, painful, without redness or heat.  On x-ray, one of the roots on my teeth is gone and appears as a shadow only.  The dentist also stated that the surface epithelium seems to be sloghing off.  I am extremely concerned that this may be cancer.  Any information you can provide would be greatly appreciated.  Thank you.
Thanks for your query, I have gone through your query. The painful jaw swelling on the jaw could be because of the abscess, cyst(like articular cyst) or any benign tumor like ameloblastoma. Consult an oral physician and get a radiograph done to rule out all this thing and take one more opinion. If it is a cyst or abscess get the tooth treated with RCT and nucleation. If it is a tumor get it removed surgically.I hope my answer will help you, take care.
