My gums sore
Sore gums may result from plaque, trauma, ulcers, appliances, dry mouth, hormonal changes, or infection.
The short answer
Sore gums can result from plaque-related gingival inflammation, trauma, ulcers, ill-fitting appliances, dry mouth, hormonal changes, or infection.

Why do sore gums become red or bleed?
Gingiva may become tender, red, swollen, or prone to bleeding when plaque irritates the tissue margin. A localized sore area can instead reflect a sharp tooth edge, trapped food, a burn, or a lesion that needs direct inspection.
How can you soothe and protect sore gums?
Brush gently twice daily with a soft brush, clean between teeth carefully, and avoid tobacco, very hot foods, and products that sting the tissue. Do not stop cleaning because the gums bleed lightly.
When do sore gums need dental assessment?
Arrange dental care if soreness persists, recurs, is localized around one tooth, or comes with swelling, pus, fever, loose teeth, or a non-healing ulcer.
What should you ask about the cause of sore gums?
Ask whether the soreness is from plaque, trauma, an ulcer, medication, dry mouth, or another condition; whether periodontal measurements or imaging are needed; and which treatment will address the cause.
