I have a small lump under my jaw in line with my back teeth.  It is tender to the touch, and it can be moved around.  I have a toothache over on that same side of my mouth, and they both popped up at the same time.  I cannot get in to see my dentist for seven days.  Do you think this is something serious?  And who should I go see about it?
Thanks for your query, I have gone through your query. The small lump under the jaw line can be because of the tooth infection which has resulted in lymph node enlargement. Nothing to be panic, consult an oral physician and get it evaluated. Meanwhile you can take a course of antibiotics like amoxicillin and metronidazole(if you are not allergic). You can take tablet diclofenac for pain. Do saline gargling. Once you are able to consult an oral physician, you can get the tooth treated accordingly. I hope my answer will help you, take care.
