A member asked:

What's the best medication against canker sore? and does b-vitamins have a role on canker sore apperaing?

A doctor has provided 1 answer

Canker sores: there is not medication that will cure canker sores. Many times they are related to stress or trauma. Some people are sensitive to SLS, an ingredient in many toothpastes, so look at the labels. Sometimes vitamin B supplements can help reduce the frequency. Try to reduce your stress levels.
