How to get rid of sore gum
Sore gums may come from plaque, trapped food, trauma, an ulcer, or infection, so treatment depends on the cause.
The short answer
A sore gum may improve with gentle cleaning and removal of trapped food, but treatment depends on whether the cause is plaque, trauma, an ulcer, or infection.

What is the direct answer?
What does this question mean?
Soreness can result from plaque-induced gingivitis, food trapped between teeth, brushing trauma, an ulcer, a sharp tooth edge, or infection near a tooth. The treatment differs because the source may be gum tissue, mucosa, or the tooth itself.
What can you do next?
Brush gently with a soft brush, clean between the teeth carefully, and rinse with lukewarm salt water if it is comfortable. Avoid smoking, very hot foods, and rubbing the area with a fingernail or sharp object.
When should you seek dental care?
See a dentist if soreness lasts, keeps returning, bleeds, produces pus, or is associated with tooth pain or swelling. Seek urgent help for facial swelling, fever, or swallowing or breathing difficulty.
What should you ask the dentist?
Ask whether the soreness is from plaque, trauma, an ulcer, or a tooth problem, and whether professional cleaning, a filling, or another treatment is needed.
