Back gums hurt
Pain at the back of the gums can come from wisdom teeth, gum inflammation, trapped food, or an infection needing examination.
The short answer
Gum pain behind the last molar often involves tissue around a wisdom tooth, but plaque inflammation, trapped food, a periodontal pocket, or a nearby abscess can cause similar symptoms.
What is the direct answer?
Look for swelling, redness, bleeding, bad taste, pus, pain on biting, reduced opening, or pain when swallowing. Examination may include probing and a radiograph.

What can you do next?
Rinse gently with warm salt water, brush softly, and clean accessible spaces without forcing anything under the gum. Use labelled pain medicine only as directed.
When should you seek dental care?
Seek care for persistent pain, swelling, pus, fever, or reduced opening. Facial or neck swelling with breathing or swallowing difficulty needs urgent care.
What should you ask the dentist?
Ask whether the cause is a wisdom tooth, gum disease, decay, or abscess, and whether imaging is needed.
