My favorite:: Mix together equal amounts of milk of magnesia or kaopectate and benadryl (diphenhydramine). Milk of magnesia and kaopectate both contain ingredients that coat wet tissues, such as those in the mouth. Benylin and Benadryl (diphenhydramine) contain ingredients that act as mild topical anesthetics and antihistamines (which reduce inflammation). Dab it on your canker sores with a q-tip. Don't swallow it.
