Report: Report this to the Dentist or specialist Oral Surgeon who put you on antibiotics. A fistula may have developed, burst open, and is now draining. Let your caregiver know.

Consult oral surgeon: You need a detailed thorough exam, along with necessary radiographs & proper treatment.The doctor would find out what is causing this & treat you appropriately.
