Can I Treat the Same Canker Sore Twice?

If pain and stinging continue immediately after treatment with Debacterol® it generally signifies that some affected tissue remains untreated. In this situation, a 5-second repeat application with the same swab is warranted to complete the process. However, a second treatment session is not recommended if a sore begins to hurt after some time has passed. This pattern can represent a complicated sore or a second overlapping sore developing in the same area. For further recommendations on this situation please discuss with your doctor.
