The short answer
Inflammation around a molar can come from plaque-related gingivitis, decay, a cracked tooth, food impaction, or infection around a partly erupted wisdom tooth.
What can cause inflammation around a molar and its gums?
Inflamed tissue beside a molar may be red, swollen, tender, or prone to bleeding. Around a partly erupted wisdom tooth, a gum flap can trap plaque and food, producing pericoronitis.
How can decay or a crack inflame the inside of a molar?
Decay or a crack can inflame the pulp inside the molar and may cause pain on biting or sensitivity to temperature. Plaque at the gum margin causes gingivitis, while deeper periodontal infection affects the supporting tissues.
A clinician may remove trapped debris, assess the gum pocket, test the tooth pulp, check the bite, and take targeted radiographs. Treatment can include cleaning, a filling, root canal treatment, periodontal care, or wisdom-tooth management.
What examinations can identify the source of molar inflammation?
A clinician may remove trapped debris, assess the gum pocket, test the tooth pulp, check the bite, and take targeted radiographs. Treatment can include cleaning, a filling, root canal treatment, periodontal care, or wisdom-tooth management.
Seek urgent care for facial swelling, fever, spreading pain, pus, restricted mouth opening, or swallowing difficulty. A molar that is painful after trauma or cannot be closed on normally also needs prompt assessment.
When does molar inflammation require urgent dental care?
Seek urgent care for facial swelling, fever, spreading pain, pus, restricted mouth opening, or swallowing difficulty. A molar that is painful after trauma or cannot be closed on normally also needs prompt assessment.
Is the inflammation in the gum, tooth pulp, or supporting bone? Is the wisdom tooth contributing? Which treatment will address the source rather than only the swelling?

Frequently asked questions
Can a swollen molar gum be an abscess?
Yes, but decay, food impaction, periodontal disease, and wisdom-tooth inflammation can look similar.
When should I arrange an examination?
