The short answer
Back-gum pain can come from an erupting wisdom tooth, trapped food, inflamed gum tissue, a tooth infection, or jaw-muscle strain, so relief depends on the source.

What is the direct answer?
What does this question mean?
Pain behind the last molar often involves a partly erupted wisdom tooth and its gum flap. Decay, a cracked molar, periodontal infection, or jaw tension can feel similar.
What can you do next?
Rinse gently, clean around the last molar with a soft brush, and choose foods that do not press on the area. Use an appropriate labelled pain medicine only if it fits your health history.
When should you seek dental care?
Seek care if pain persists, returns, or causes bad taste or limited opening. Fever, facial swelling, or swallowing or breathing difficulty needs urgent care.
What should you ask the dentist?
Ask whether the wisdom tooth, adjacent molar, gum flap, or jaw muscles are responsible and whether an X-ray or definitive treatment is needed.
Frequently asked questions
Can this be diagnosed from symptoms alone?
No. Several dental conditions can produce similar symptoms, so an examination and targeted tests may be needed.
What should I avoid while waiting?
Avoid poking, squeezing, or applying household chemicals to the area, and arrange appropriate dental assessment.
