My son - age 14 - with no other health problems - has suddenly (overnight) developed swelling between 3 of his lower front teeth and two painful marble-sized lumps on his neck.  One of the lumps is directly under his chin, in the middle, approximately beneath where the problem with his gums is.  The other lump is directly under the end (farthest back) part of his jaw.  I assume its the lymph node there.  He gets regular dental checkups and had dental xrays done only 2 or 3 months ago, with no cavities or other issues.  Does this sound like a tooth or gum infection and would it be better to see a dentist or a doctor?  Thanks.
Thanks for using Chat Doctor. Read your query. The lumps can be due to abscess in relation to any of the three anterior lower teeth mentioned (periodontal abscess) thus triggering the enlargement of the lymph nodes in the sub mandibular region. I would advise you to visit your dentist and get it checked to rule out the abscess, thus getting the needful treatment done. For the pain, broken can be given, He may also require a dose of antibiotics. Do saline gargling. Thanks and regards.
