Time: Canker (unkown cause) and cold sores (viral cause) usually will go away in 10 days to 2 weeks. There are ointments you can purchase at the drugstore to make them less painful. If truly a cold sore, you can get a rx for Acyclovir which for some will shorten the timeframe.

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.
