Swollen gums near a tooth swelling inside a molar area
A swollen area beside or inside a tooth can come from trapped plaque, gum infection, decay, trauma, or an abscess and needs an examination.
The short answer
Swelling near one tooth can be caused by localized gum inflammation, food impaction, a cavity, a cracked tooth, or infection around the tooth root. The cause cannot be identified reliably by appearance alone, so the tooth and surrounding tissues need examination.
Which gum tissues may swell beside a molar?
The swelling may involve the marginal gingiva, the small gum triangle between teeth, or a draining sinus from an infected pulp or root. A dentist checks tenderness, tooth vitality, gum pockets, bite, and restorations and may use dental radiographs to assess bone and the root.
How should you care for swelling near a tooth?
Rinse gently with warm water, keep the area clean with a soft brush and suitable interdental cleaning, and avoid squeezing or puncturing the swelling. Do not place aspirin or caustic substances on the gum; treatment may involve drainage, a filling, root canal treatment, extraction, or periodontal care depending on the source.
When does swelling beside a molar need dental care?
Arrange prompt dental care for swelling beside a molar, especially with toothache, pain on biting, pus, bad taste, fever, or a swollen cheek. Emergency care is needed if swelling spreads toward the eye or neck or causes trouble breathing or swallowing.
What should your dentist check around the swollen tooth?
Ask which tissue is swollen, whether the tooth nerve is healthy, and whether an X-ray is needed. Ask which treatment removes the source and what warning signs require same-day care.
Frequently asked questions
Can a gum swelling disappear on its own?
It may drain or shrink temporarily while the underlying tooth or gum infection remains.
Can I pop the swelling?
No. Squeezing or puncturing it can injure tissue and does not treat the source.
