Sore bump on gum
A sore bump on the gum may be irritation, a draining dental abscess, a blocked salivary structure, or another lesion, so its position, colour, te.
The short answer
A sore bump on the gum may be irritation, a draining dental abscess, a blocked salivary structure, or another lesion, so its position, colour, tenderness, and duration matter.
How can an infected tooth cause a gum bump?
Gum bumps can form beside an infected tooth, where pus tracks through bone and exits near the gum, or from local trauma such as biting. Other possibilities include a blocked or inflamed salivary duct, an ulcer, a fibrous overgrowth, or a lesion unrelated to a tooth.
How will a dentist examine a sore gum bump?
A dentist examines the bump, nearby teeth, gum pocket, bite, and oral lining, and may test the tooth or take a radiograph. A draining abscess can reduce pressure temporarily while the infection remains, so squeezing it does not treat the source.
When does a sore gum bump need prompt care?
Keep the area clean with gentle brushing, avoid picking or puncturing it, and note its size, colour, tenderness, discharge, and changes. A dentist may treat the tooth, drain an infection, remove an irritant, or arrange further testing based on the examination.
What should you ask about a painful gum bump?
Seek prompt care for a painful or enlarging bump, pus, fever, facial swelling, loose tooth, or difficulty opening the mouth. Any lump, ulcer, or patch that persists or changes needs dental assessment.
