The short answer
Sore gums behind the last molar commonly involve an erupting wisdom tooth, trapped food, gum inflammation, an ulcer, or disease in a back tooth.
What is the direct answer?
What does this question mean?
A gum flap over a partly erupted wisdom tooth can retain plaque and food. Decay, a crack, a periodontal pocket, or jaw-joint pain can also feel far back in the mouth.
What can you do next?
Brush the area with a small soft brush, rinse gently after meals, and avoid sharp objects under a gum flap. Use pain medicine only as its label permits.
When should you seek dental care?
Seek prompt care for worsening pain, bad taste, pus, fever, facial swelling, or limited mouth opening; swallowing or breathing difficulty is urgent.
What should you ask the dentist?
Ask whether the wisdom tooth is positioned normally, whether decay or a pocket is present, and whether imaging is needed.
