What is the direct answer?
A small gum bump above a tooth can result from irritation, a draining dental infection, a cyst, or normal bone, so its cause needs examination.
What does this question mean?
A bump on gingiva over a root may be a sinus tract from infected pulp, while a firm painless prominence may be bone or irritation.
What can you do next?
Do not squeeze it. Note size, color, tenderness, drainage, and duration; a dentist may test the tooth, probe the gum, and take a radiograph.
When should you seek dental care?
Seek prompt care for pain, pus, enlargement, or a tooth with decay or a crack; facial swelling, fever, or swallowing difficulty is urgent.
What should you ask the dentist?
Ask whether vitality testing and imaging show a root infection, and whether treatment concerns the tooth, gum, or observation.
