In brief: Home remedies first

Canker sores are often caused by irritation in the mouth.
There are several theories from acid from the stomach to ill-fitting dental appliances. Most often, simpling gargling with salt water or even baking soda will help. Various remedies from peptobismol to gargling with peroxide have also been suggested. Campho-phenique is a topical medicine that can be purchased over the counter can work.

In brief: Licorice

Licorice has been used since ancient times to treat canker sores in the mouth.
Also, small studies show it can be effective when used as a mouthwash -- 50-75% improvement in 1 day. http://tinyurl.com/kr9aeau sucking on dgl lozenges may work also. Other studies showed positive results with a dissolving licorice disk placed on the sore. http://tinyurl.com/mdvde3o.
