What is the direct answer?
A small gum swelling can come from trapped plaque, irritation, a blocked gum pocket, or an infection near a tooth, so its location and symptoms matter.
What does this question mean?
The swelling may involve gingiva, a periodontal pocket, or a draining sinus from an infected pulp or root. Examination may include tooth tests and an X-ray.
What can you do next?
Keep it clean with gentle brushing, rinse with warm salt water if comfortable, and do not squeeze, pierce, or place aspirin on it.
When should you seek dental care?
Arrange prompt care for a persistent, recurrent, draining, or tooth-related lump. Facial or neck swelling, fever, or breathing or swallowing difficulty is urgent.
What should you ask the dentist?
Ask what structure is affected, which examination is needed, and which treatment or product fits your teeth, gums, appliance, and medical history.
