Blister on top gum
A blister-like bump on the upper gum can come from irritation, a blocked gland, or drainage from an infected tooth, so its location and appearance need.
The short answer
A blister-like bump on the upper gum can come from irritation, a blocked gland, or drainage from an infected tooth, so its location and appearance need an oral examination.
What is the direct answer?
What does this question mean?
The upper gum covers the roots of the upper teeth and part of the hard palate. A small boil-like swelling beside a tooth can be a draining sinus tract from a root infection, while a clear blister after hot food or friction may be a superficial injury.
What can you do next?
Do not pop or squeeze the bump. Rinse gently, avoid chewing on it, note which tooth is nearby, and arrange an examination; the dentist may test the tooth, inspect the gum, and take a dental radiograph before treating the source.
When should you seek dental care?
Seek prompt care if the swelling is painful, enlarges, drains pus, causes toothache, or is associated with fever or facial swelling. Emergency help is needed for difficulty breathing or swallowing.
What should you ask the dentist?
Ask whether the bump is draining from a tooth, whether the tooth needs a vitality test or radiograph, and whether treatment involves drainage, a root canal, extraction, or simple removal of an irritant.
