Gums hurt at the back of teeth
Pain behind the back teeth commonly comes from inflamed gum tissue, a wisdom tooth, trapped food, or infection around a tooth.
The short answer
Pain behind the back teeth commonly comes from inflamed gum tissue, a wisdom tooth, trapped food, or infection around a tooth. The cause is distinguished by examining the gum, tooth, and nearby jaw area.
Which tissue may be causing pain at the back?
The painful area may be the attached gum, the loose tissue over a partly erupted wisdom tooth, or the gum pocket beside a molar. Plaque, calculus, food impaction, decay, a cracked tooth, and a dental abscess can produce similar soreness but require different treatment.
What can I do for pain behind my back teeth?
Rinse gently with warm salt water, brush the area with a soft toothbrush, and clean between the teeth without forcing an object under the gum. Avoid placing aspirin or concentrated chemicals on the tissue, and arrange an examination if the pain persists or returns.
When does back gum pain need urgent dental care?
Seek prompt care for facial swelling, pus, fever, limited mouth opening, or pain that makes sleep or eating difficult. Difficulty breathing or swallowing, or swelling spreading toward the eye or neck, needs emergency medical attention.
What should I ask about pain behind my molars?
Ask whether the soreness is in the gum or comes from the molar beneath it. Ask if an X-ray is needed to assess a wisdom tooth, decay, bone loss, or infection, and which cleaning or treatment will remove the cause.
Frequently asked questions
Could a wisdom tooth cause pain there?
Yes. A partly erupted wisdom tooth can leave a gum flap that traps plaque and food, causing localized inflammation.
Can rinsing cure the problem?
Rinsing may soothe irritated tissue, but it does not remove decay, calculus, or an abscess.
