Back right bottom gum swollen
A swollen gum behind a lower molar can reflect trapped food, gum inflammation, decay, or a wisdom-tooth problem.
The short answer
A swollen gum behind a lower molar can reflect trapped food, gum inflammation, decay, or a wisdom-tooth problem. A lower back gum swelling may surround a partially erupted wisdom tooth, collect food beneath a gum flap, or sit beside a decayed or cracked molar. A localized abscess is another possibility.
What is the direct answer?
What does this question mean?
The location describes the gingiva behind or beside the last lower molar, not a diagnosis. The dentist checks the tooth, gum flap, pocket depth, bite, drainage, and wisdom-tooth position.
What can you do next?
Rinse with warm salt water, brush gently around the area, keep food from packing there, and use labelled pain relief if suitable. Do not puncture the swelling or place heat directly on it.
When should you seek dental care?
Seek prompt care if swelling enlarges, pain increases, pus or fever develops, or opening the mouth becomes difficult. Neck or facial swelling with breathing or swallowing difficulty is urgent.
What should you ask the dentist?
Ask whether the source is the wisdom tooth, the molar, the gum pocket, or an abscess, and whether cleaning, drainage, a filling, root canal treatment, or removal is indicated.
