My gum has a blister
A gum blister may come from irritation or infection near a tooth and should not be popped if it persists or hurts.
The short answer
A gum blister is usually a fluid-filled or pus-filled swelling caused by irritation, trauma, or infection near a tooth or gum. Do not pop it; arrange an examination if it persists, drains, or is painful.
What is the direct answer?
What does this question mean?
A blister on the gum can arise from a bite injury, a burn from hot food, a blocked minor salivary gland, or a dental abscess that has reached the gum surface. Its color and appearance alone cannot identify the cause.
What can you do next?
Rinse gently with warm salt water, brush around the area with a soft brush, and avoid sharp, hot, or spicy foods touching it. Do not squeeze it or place aspirin on the gum.
When should you seek dental care?
Seek prompt dental care for facial swelling, fever, a bad taste, increasing pain, trouble swallowing, or a swelling that remains. Breathing difficulty or rapidly spreading swelling needs emergency care.
What should you ask the dentist?
Ask whether the swelling is connected to a tooth, whether an X-ray is needed, and whether drainage, cleaning, a filling, root canal treatment, or extraction addresses the cause.
