What’s the difference between a fever blister and a cold sore?

Fever blisters and cold sores are two of the most common disorders in the mouth. They cause discomfort, annoyance, and sometimes, embarrassment. Both cause sores to develop in or around the mouth, and are often confused with each other.

The difference is that a cold sore occurs only on the inside of the mouth (tongue, linings of the cheeks, lips and throat) and fever blisters usually occur outside the mouth on the lips, chin, cheeks or nostrils.

If they do occur in the mouth, they are usually on the roof of the mouth or gums. They will appear smaller than cold sores and often begin as a blister.
