Blisters around the mouth have several possible causes, including cold sores and irritation.
The short answer
Blisters around the mouth can result from a cold sore, irritation, allergy, trauma, or another skin or mucosal condition.
What is the direct answer?
What does this question mean?
Grouped fluid-filled lesions near the lip border may fit a cold sore, while an inner-mouth lesion may be a burn, trauma ulcer, blocked salivary gland, or medication-related problem.
What can you do next?
Do not pick or burst it, avoid products that sting, and avoid sharing lip products or utensils when a cold sore is possible.
When should you seek dental care?
Arrange assessment if it spreads, recurs, is unusually painful, has fever, or does not heal.
What should you ask the dentist?
Ask what diagnosis, material, force, ingredient, or follow-up finding applies to my teeth and gums, and what alternatives should be considered.
