Canker sores

canker sores Canker sores are round or ovoid open sores inside the mouth or upper throat. They occur on the inner cheeks, the soft palate, the under surface of the tongue, floor of the mouth and the upper throat. Canker sores can also occur on genitals and on a few internal organs in some rare cases.
