Blister on gum that won t go away
A gum blister that does not heal can be a draining dental abscess, a traumatic sore, or another oral lesion, so its cause needs examination.
What can a gum blister that will not heal indicate?
A gum blister that does not heal can be a draining dental abscess, a traumatic sore, or another oral lesion, so its cause needs examination.
What is a persistent blister on the gum?
A persistent gum blister is a raised fluid-filled or swollen area on the gingiva. A tooth infection may create a sinus tract that drains through the gum, while biting injury or an ulcer can affect the surface.
What should you do with a persistent gum blister?
Do not pop or squeeze it. Brush gently, rinse with warm salt water for comfort, and arrange an examination so the dentist can test the tooth, gums, and possibly take an X-ray.
When should a persistent gum blister be examined?
Seek prompt care if it persists, returns, drains pus, or comes with toothache, swelling, fever, bad taste, or pain when biting. Facial swelling or difficulty swallowing or breathing needs urgent attention.
What should you ask about a gum blister that persists?
Ask whether it is connected to a tooth root, gum pocket, trauma, or another lesion, and whether treatment may require drainage, a filling, root canal treatment, extraction, or tissue sampling.
Frequently asked questions
Could this have more than one cause?
Yes. A dentist uses the history, examination, and tests to distinguish common causes that can look alike.
What should I bring to the appointment?
Bring the product or appliance involved, a list of medicines, and notes about when the symptom or concern began and changed.
