Gums swollen around molar
Swelling around a molar can come from trapped plaque, gum infection, food, or an erupting tooth and needs assessment if persistent or painful.
The short answer
Swollen gum around a molar is commonly caused by plaque-related inflammation, trapped food, decay, a gum pocket, or infection near the tooth. A partially erupted wisdom tooth can also leave a flap of gum that becomes inflamed.
What does swelling beside or over a molar indicate?
The swelling is enlargement of gingival tissue beside or over the molar. Redness, tenderness, bleeding, bad taste, or pain on biting can indicate inflammation, while facial swelling or fever raises concern for a spreading dental infection.
How can I clean and soothe a swollen molar gum?
Gently brush the tooth surfaces and clean between them with floss or an interdental brush, then rinse with warm salt water. Do not press, puncture, or place aspirin on the gum; a dentist may remove trapped debris, clean the pocket, treat decay, or drain an abscess.
When does swelling around a molar need dental care?
Arrange an examination if the swelling lasts more than a short period, returns, bleeds repeatedly, or makes chewing difficult. Seek urgent care for rapidly increasing swelling, fever, difficulty swallowing or breathing, or swelling that extends into the face or neck.
What could be causing my molar gum to swell?
Ask whether the swelling is from gingivitis, a periodontal pocket, decay, a cracked tooth, or an erupting wisdom tooth. Ask whether you need dental X-rays, periodontal measurements, cleaning, a filling, root canal treatment, extraction, or monitoring.
Frequently asked questions
Can a cavity cause swollen gum beside a molar?
Yes. Decay can allow bacteria to reach the pulp and tissues around the root, producing a gum swelling or abscess.
Should I pop the swollen area?
No. Puncturing it can injure tissue and does not remove the dental source of infection.
