my grandson has a swollen jaw on the left side along the jawline.  It hurts very badly when he chews and when it is touched.  Does this sound like a impacted tooth, swollen gland, or lymph node?  He was born three months early and has many problems with his teeth and surgeries.
Thanks for your query, I have gone through your query. The swelling could be because of the tooth infection might be from the wisdom tooth. It can be enlarged lymph node secondary to tooth infection. Consult an oral physician and get radiograph done to rule out origin of infection. Then treat accordingly either root canal treatment or extraction. You can take a course of antibiotics after consulting an oral physician. I hope my answer will help you. Take care.
