A canker sore is much different
from a cold sore caused by herpes simplex virus. A canker sore is a benign, open sore in the mouth, which appears as a painful white or yellow sore (ulcer) surrounded by a bright red area, which is not contagious. A fever blister is very different from a canker sore
, although they both develop in close proximity in area of the mouth.
Other sources said this about canker sores
: "Canker sores occur only inside the mouth and are not contagious. They sometimes occur as a result of trauma (biting the inside of the lip, burning the mouth with hot food), but may also occur spontaneously."
"A canker sore
is a common form of mouth ulcer, which appears as a painful white or yellow ulcer surrounded by a bright red area. A canker sore can be triggered by emotional stress, dietary deficiencies, menstrual periods, hormonal changes, food allergies or trauma in the mouth. Canker sores usually heal without treatment within two weeks."
