Most preferred canker sore remedies?

Many?: Since we do not know what causes canker sores, the remedies are many. One approach is to apply a topical broad-spectrum antibiotic a few times a day. Another home remedy is to apply table salt on the sore itself but do realize this may hurt a bit. I am sure there are many other remedies but none has been scientifically proven.

Kanka: There is no known cure, but using over the counter kanka is the best thing I have found in my 40 + years of dentistry. It coats and reduces pain immediately!

Canker sores: If you have a canker sore ( aphthous ulcer) you can rinse your mouth w warm salt water. Mix a teaspoon of salt in 8 oz of warm water – gargle w this several times a day. Another option is to swish a mix of 1 part milk of magnesia ; 1 part liquid Benadryl in your mouth. Spit out after about a minute. Avoid eating spicy food or food that is hot (high temperature). Nsaid's or tylenol (acetaminophen) can be used for.
