Big white bump on gums
A white gum bump can be irritation, an ulcer, an erupting tooth, or infection and should be judged by its course and symptoms.
The short answer
A large white bump on the gum may be irritated tissue, an erupting tooth, or an abscess, and pain, drainage, growth, or fever makes prompt examination important. Do not scrape, squeeze, or burn it.
Why can a gum bump look white?
White colour can come from a superficial ulcer coating, thickened keratinized tissue, pus beneath the gum, or tooth enamel showing through during eruption. Location beside a tooth, duration, tenderness, and whether the surface breaks are useful clinical clues.
How can you care for a white gum bump now?
Keep the area clean with gentle brushing, rinse with plain water or mild salt water, and choose foods that do not rub it. Photographing the area and noting changes can help the examination.
When does a white gum bump need dental care?
Seek dental care for a lump that remains, enlarges, bleeds, drains, or is linked with toothache or fever. Emergency help is needed for facial swelling or trouble breathing or swallowing.
What should your dentist check around the bump?
Ask what tissue is producing the bump and whether the nearby tooth needs a vitality test or X-ray. Ask which treatment removes the cause and how the area should be monitored.
Frequently asked questions
Is every white gum bump an abscess?
No. Appearance alone cannot distinguish an abscess from irritation, an ulcer, or an erupting tooth.
Can a mouth ulcer form a bump?
Inflamed tissue around an ulcer can feel raised, but a persistent lesion needs examination.
