Generally , people suffer from fever blisters before the age of 10. These are among the common disorders of mouth and cause much discomfort.

Fever blisters generally last a couple of weeks before disappearing. However, some people get the outbreaks of fever blisters(also known as cold sores) again and again. The HSV-1 after getting on the body of a person remains in the facial nerves and remains dormant. However, when the person suffers from cold or fever, the virus gets activated again. Mental stress, dental treatment, trauma etc. can also cause the virus to activate and hence result in fever blisters.
