Red bump on gum above tooth
A red bump above a tooth may be gum irritation or a draining abscess, so tooth pain, pus, or swelling needs prompt assessment.
The short answer
A red bump on the gum above a tooth can be an irritated gum area, a periodontal pocket, or a sinus tract draining infection from the tooth root. The bump’s appearance cannot show whether the pulp, root, gum, or surrounding bone is involved, so the tooth needs an examination.
What does a sinus tract on the gum mean?
A sinus tract is a small channel through which inflammatory fluid from an infected tooth or surrounding tissue reaches the gum surface. Other causes include food trapped under the gum, a sharp edge, trauma, a canker-like lesion, or localized gum disease.
How should you care for a red gum bump today?
Keep the area clean with a soft brush and gentle rinsing, but do not pop, pierce, or squeeze the bump. Avoid chewing hard food on that side and arrange a dental examination even if the bump drains and becomes smaller.
When does a red bump above a tooth need prompt care?
Seek prompt care for toothache, pain on biting, pus, a bad taste, fever, facial swelling, or a bump that persists or returns. Emergency care is needed for swelling that affects breathing or swallowing or spreads rapidly across the face.
What should you ask about the bump and a dental X-ray?
Ask whether the bump is connected to the tooth root, a gum pocket, or an injury, and whether a dental X-ray is needed. Ask whether treatment should drain the area, clean the gums, perform root canal treatment, restore the tooth, or remove it when it cannot be repaired.
Frequently asked questions
Can a gum bump disappear while the infection remains?
Yes. Drainage can reduce the bump without removing the infected pulp, root, or gum source.
Is every red gum bump an abscess?
No. Irritation, trapped food, trauma, and gum inflammation can look similar, so diagnosis requires an examination.
