Swelling of the teeth
A tooth cannot swell like soft tissue, but swelling around it can signal infection, gum inflammation, trauma, or an erupting tooth.
The short answer
A tooth cannot swell like soft tissue, but swelling around it can signal infection, gum inflammation, trauma, or an erupting tooth. The location, tenderness, drainage, and condition of the tooth help identify the cause.
What is the direct answer?
What does this question mean?
Patients usually mean a puffy gum, cheek, or area beside a tooth. Common mechanisms include bacterial inflammation in the gum, infection within the pulp and root canal, a periodontal abscess, or pressure from a wisdom tooth.
What can you do next?
Rinse gently with warm water, brush carefully around the area, and use a cold pack outside the cheek for short intervals. Do not puncture the swelling, apply heat, or place tablets against the gum, because these actions can injure tissue or spread irritation.
When should you seek dental care?
Arrange urgent dental assessment when swelling is painful, enlarging, associated with fever, or accompanied by a bad taste or pus. Emergency care is needed for difficulty breathing or swallowing, marked facial swelling, or swelling that approaches the eye.
What should you ask the dentist?
Ask whether the swelling comes from the pulp, gum pocket, wisdom tooth, or another tissue, and whether an X-ray is required. Ask which treatment removes the source, such as drainage, root canal treatment, periodontal care, or extraction.
Frequently asked questions
Can a swollen gum heal without treatment?
Mild irritation may settle when plaque or food is removed, but persistent or painful swelling can indicate infection and needs an examination.
Is pus beside a tooth an abscess?
Pus can occur with a dental or gum abscess, but examination and sometimes imaging are needed to locate its source.
