My gums in the back are swollen

Swelling at the back of the gums can come from trapped food, gum inflammation, a molar infection, or tissue around a partially erupted wisdom tooth.

The gum behind the last molar can form a flap around a partly erupted wisdom tooth. Plaque and food trapped there may cause pericoronitis, while a molar may develop decay or an abscess.

Use gentle oral hygiene, clean between the teeth, and avoid caustic substances or forceful manipulation. A dentist can examine the tissues, test the teeth, and use imaging when it answers a specific clinical question.

Arrange care for persistent or worsening symptoms, swelling, pus, fever, a broken or loose tooth, or an unexplained dark area. Difficulty breathing or swallowing and rapidly spreading facial swelling require urgent help.

Ask which structure is affected, what caused the finding, whether an X-ray or other test is needed, which treatments preserve healthy tissue, and what alternatives and aftercare apply.
