The gum around my back tooth hurts
Pain around a back tooth can come from trapped food, gum inflammation, an erupting wisdom tooth, decay, or infection.
The short answer
Pain around a back tooth can come from trapped food, gum inflammation, an erupting wisdom tooth, decay, or infection. The dentist distinguishes these causes by examining the gum flap, tooth surface, pocket depth, bite, and nearby bone, with imaging when needed.
What is the direct answer?
What does this question mean?
The sore area may be the gingiva beside a molar, the tissue over a partly erupted wisdom tooth, or the deeper tissues around a tooth root. Redness, swelling, bad taste, pain on biting, or limited mouth opening can help identify the source.
What can you do next?
Rinse gently with warm salt water, brush carefully around the tooth, and use dental floss or an interdental brush to remove accessible food. Do not cut the gum, place aspirin on it, or force an object beneath the tissue.
When should you seek dental care?
Arrange an examination if pain lasts, returns, or is accompanied by swelling, pus, fever, bad taste, pain on biting, or difficulty opening the mouth. Obtain urgent medical help if swelling affects breathing or swallowing or spreads into the face or neck.
What should you ask the dentist?
Ask whether the pain is from the gum, tooth pulp, periodontal tissues, or a wisdom tooth, and whether an X-ray is needed. Ask whether cleaning, a filling, root canal treatment, gum care, or removal is the appropriate treatment.
Frequently asked questions
Can a wisdom tooth cause gum pain at the back?
Yes. A partly erupted wisdom tooth can leave a gum flap where food and bacteria collect, causing local inflammation.
Will rinsing cure the problem?
Rinsing may remove irritants and soothe the area, but persistent or recurrent pain needs diagnosis and treatment of its cause.
