All on right side. Pain when swallowing. Swollen on the back roof of mouth. Above my gums hurt, like top of jaw, and my temple hurts. No wisdom teeth. Help?

Possibilities. Many come to mind. Could be infected tooth/teeth, gum infection, virus, oral bacterial infection, sinus infection, Gerd, etc. Start with your Dentist. If dental/oral cause ruled out,nthen next step is to see your Physician. Pain and swelling should not be ignored.
