Sore gums inside mouth
Sore gum tissue can result from plaque, trauma, ulcers, infection, dry mouth, or an ill-fitting dental appliance.
The short answer
Sore gums inside the mouth can result from plaque-related inflammation, brushing injury, ulcers, infection, dry mouth, or irritation from an appliance. The location, duration, appearance, and associated symptoms help distinguish these causes.
Which mouth tissues are included when gums feel sore inside?
Gum tissue includes the gingiva around teeth and the mucosal lining of the cheeks, lips, floor of the mouth, and palate. Tenderness may affect one spot beside a tooth or a broader area with redness, swelling, ulceration, or peeling.
What can I do now for soreness inside my mouth?
Use a soft brush, clean gently, drink water, and avoid tobacco, alcohol-containing rinses, and foods that sting the area. Do not apply aspirin directly to the gum because it can chemically injure the tissue.
When should soreness inside the mouth be examined?
Arrange care when soreness persists, recurs, interferes with eating, or occurs with bleeding, pus, tooth pain, or a loose appliance. Urgent assessment is needed for facial swelling, fever, or trouble swallowing or breathing.
What should I ask about soreness inside my mouth?
Ask whether the soreness is from gum inflammation, a tooth, trauma, an ulcer, medication, or an appliance. Ask whether the area needs periodontal measurements, a radiograph, medication review, or adjustment of the appliance.
Frequently asked questions
Can brushing cause sore gums?
Yes. Excessive force, a hard brush, or a new technique can injure the gingiva, although bleeding may also signal inflammation.
What if the soreness is under a denture?
Remove the denture as directed, keep it clean, and arrange an adjustment if it rubs or causes a persistent sore.
