How to Get Rid of a Chancre Sore

While the exact cause of canker sores is unknown, these lesions tend to appear after trauma to the mouth -- such as biting the inside of the cheek or lips, excess stress, hormonal changes and general poor hygiene. These lesions are small open wounds inside the mouth. While harmless, they can cause a lot of pain and discomfort. There's no cure for canker sores, but you can take certain measures to alleviate the pain and discomfort felt while the sore is healing on its own.

  Repeat every four hours or after doing something that may irritate the sore, such as eating or smoking.
