I woke up 2 days ago to find my lips swollen with lots of sores, and a terrible toothache. then today i noticed a lump under my chin.

See Dentist or MD: it could be a variety of things,one being primary Herpetic gingevastomatitis with lymph node involvement. But you must be examines ASAP!

Tooth abscess: A tooth abscess won't go away without treatment and the infection may spread to your jaw, cheeks, sinus and to other areas of your head and neck. A dental abscess is a collection of pus that forms in your teeth or gums as a result of a bacterial infection. Dentist will treat a tooth abscess by treating the cause and getting rid of the infection. See your dentist ASAP.
