Wisdom tooth vs inf.: If you don't think this is not a wisdom tooth, you might have an infection. Please see your doctor or dentist.

Stomatitis: Sounds like you may have herpes stomatitis, often resulting in painful swollen gums and inflammation under jaw where your lymph nodes ("glands") may be larger as your body fights the infection. You can try pain reducers like Ibuprofen and magic mouthwash to give temporary relief. You should see your doctor to confirm the diagnosis and may prescribe a medication to speed the process.

Many things: This could be many things. Gum swelling from problems with your gums to manifestation of a systemic illness. Pain and swelling sounds like a response to the inflammation of your gums, and headaches may be because you are sick. You should see your Dentist or Medical Doctor for a proper evaluation and diagnosis.

Dental abscess : The only way to cure a dental abscess is with dental treatment. We have now entered an era where some bacterial species are resistant to the full range of antibiotics presently available. See your dentist for re-evaluation and dental treatment. Good luck.
