So, I decided I would try what Dr. Henslee suggested and use the Chlorhexidine for 30 seconds (multiple times a day).
Let me tell you, my sore went away within 3-4 days. The Chlorhexidine helped in shortening the life of the canker sore and it helped to reduce the sensitivity as well. From personal experience, Chlorhexidine really can help those that suffer from canker sores.
