Canker Sores are not caused by a bacteria or virus so the mechanisms by which these anti-microbial mouthwashes work remains unclear. Your local drug stores stocks some pain relieving medications, including Zilactin or Oragel. After application, they create a protective cover over the sensitive areas. These are prescription medications that must be authorized by your dentist or physician and should only be used for severe or painful cases. The application of these types of gels and rinses may be painful at first.
Some digestive conditions display canker sores as part of their disorder.
