Hi Genelle,

Canker sores (Recurrent or TRAUMATIC Apthous Ulcers) are a result of either, stress, a poor diet, a vitamin deficiency, food allergy, smoking, just to mention a few. They present first in childhood or adolescence and are usually gone in 10-14 days with or without treatment.

You can use one of the following remedies: Benzocaine , Oragel , Lidocaine orTriamcinolone dental paste .1% also known as Kenalog in Orabase. This is a topical corticosteroid preparation (granular paste) with pectin in it that allows the ointment to stay in place even in the presence of saliva! Your dentist or physician can prescribe this for you to have on hand if you get canker sores often. Use it sparingly about 3 to 4 times a day.

Another anti-inflammatory paste called Aphthasol is also a good remedy for canker sores as is Canker Cover. Vitamin B complex and Folic Acid have also been shown to be effective in reducing canker sores. You can also use salt water rinses: you can dissolve ½-teaspoon of salt in 8 ounces of water as hot as can be safely tolerated, and rinse vigorously for about 2 minutes at least every 2-3 hours or diluted Hydrogen Peroxide rinses. There is no way to prevent them from reoccurring but as we age they do seem to happen less often. Now canker sores should not be confused with cold sores or fever blisters that are caused by a virus. Cold sores develop on the outside of the mouth and canker sores are always on the inside of the mouth. You could have him further evaluated by a rheumatoid specialist to rule out any immune issues. It makes good sense to investigate all possibilities. Does all this make sense to you?

Hi Genelle, just an FYI about your son's situation. Anti virals will not help treat canker sores and here is a website that explains it further:

Good luck!
