Infection: If its only one side then likely the infection is causing the swelling. If its both sides you should be concerned about a reaction to the medication. Both sides swelling and you should call your dentist or seek emergency care. Naproxen and penicillin is usually not a problem when taken together.

Ask for Referral: Naproxien and penicillin don't have any adverse reactions when taken together. It is more likely that the swelling in your jaw is due to a tooth abscess. Often, general dentists will prescribe antibioticsw whenever there is a necrosis or abscess of the pulp of a tooth as an immediate solution to an emergency situation. However, the tooth needs to be opened, drained otherwise the situation worsens.

See DDS ASAP: See DDS ASAP. The tooth may need to be drained and root canal. Or extracted.
