In brief: Cautery for cankers

Cautery can stop canker sore growth.
Topically applied debacterol is one such product used to achieve this.

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.

You can also use Oxygel which has aloe Vera because it's thick enough to last few hours for protection from irritants and reduces inflammation. Can see dr for silver nitrate and that will get rid of it immediately.
