A member asked:

How long do viral blisters usually last in a 3 year old child's mouth?

A doctor has provided 1 answer

5-7 Days: Allot depends on the virus causing the blisters but most will resolve in a relatively quick time. They can be a real nuisance, but most will resolve in a 5-7 day period.
