How does silver nitrate help canker sores?

6 doctors weighed in across 2 answers

Nerve endings: Silver nitrate, sulfuric acid, or citric acid are common medications applied to a canker sore. It chemically cauterizes the nerve endings in the area. The result is a potentially longer lasting ulcer but it doesn't hurt during the healing period.

Yes and no: Silver nitrate causes pain relief by burning the surface tissue of the ulcer, then it heals. Placing a protective ointment is another option to cover the ulcer while it is healing and can be obtained from your dentist.
