The bottom right side of my mouth where the last tooth is...the gum area there hurts everytime I swallow and the area feels slightly inflamed.  When I swallow, the pain almost seems to radiate slightly to my throat and my right ear.  Is this an infection and is it serious?  Do I need to see a dentist or can I do something myself at home to take care of it?
Thanks for using Chat Doctor. Read your query. Recurrent Peritonitis will be the probable cause for the pain which is then referred to the adjoining areas. I would advise you to keep the area clean and do not keep any food debris there which will increase the pain. For pain ibuprofen can be taken (if not allergic to any medicines). Do salt water gargling. Visit an oral surgeon and have a radiograph done to know the erupting status of the last tooth. If impacted, have it removed or if not impacted wait for the complete eruption. Hope this was useful. Thanks and regards.
