Got a bump on my gums
A gum bump may come from irritation, a blocked salivary duct, or a tooth infection and needs context to identify.
The short answer
A bump on the gum can be an irritation, a small cyst, or a drainage point from an infected tooth, so its location and symptoms matter. Do not puncture it or squeeze it, because that can injure tissue while leaving the underlying cause untreated.
Why might a gum bump appear beside one tooth?
A pimple-like bump beside a tooth may be a sinus tract draining inflammation from the tooth root, while a bump after biting the cheek may be local trauma. A firm or persistent lump can have other causes and cannot be identified reliably by appearance alone.
How can you care for a bump on your gum now?
Keep the area clean with gentle brushing and note when the bump appeared, whether it changes size, and whether a particular tooth is tender. A dentist may inspect the tissues, test nearby teeth, measure the gums, and take dental radiographs to locate an infection or other source.
When does a gum bump need prompt dental care?
Arrange prompt dental care for a bump with toothache, pus, bad taste, swelling, or pain when biting. Seek urgent medical help if swelling spreads toward the eye or neck, breathing or swallowing becomes difficult, or fever and marked illness develop.
What should you ask about the cause of a gum bump?
Ask whether the bump is related to a tooth, gum pocket, trauma, or a soft-tissue lesion and what examination or image is needed. Ask which treatment addresses the cause, such as drainage, gum care, a filling, root canal treatment, or removal of a non-restorable tooth.
Frequently asked questions
Can a gum bump go away by itself?
Irritation may settle, but a bump linked to a tooth infection can persist or recur until the tooth is treated.
Is a gum boil always an abscess?
No. Similar-looking bumps can have different causes, so a dental examination is needed.
