Canker sores are completely different from cold sores.


Canker Sores

Canker sores are small ulcers inside the mouth. Unlike cold sores -- which are outside the mouth and very contagious -- canker sores are not caused by a virus. Certain foods or nutritional deficiencies may trigger a canker sore, as can emotional stress and a mouth injury. When needed, treatments include topical medication and mouthwash solutions.
