Bleeding sore
A bleeding sore in the mouth may be caused by trauma, inflamed gum tissue, an ulcer, or an infection that needs examination.
The short answer
A bleeding sore in the mouth may be caused by trauma, inflamed gum tissue, an ulcer, or an infection that needs examination. Its appearance, location, duration, and associated swelling help determine the next step.
What is the direct answer?
What does this question mean?
A sore can be a break in the lining of the cheek, gum, palate, or tongue, or an opening from infected tissue beside a tooth. Biting, a sharp tooth, a rough filling, plaque, periodontal inflammation, and a draining abscess are different possibilities.
What can you do next?
Rinse gently, keep the area clean, choose soft foods, and avoid tobacco, alcohol-containing rinses, and sharp or spicy foods while it heals. Do not scrape, cut, or squeeze the sore, and record changes in size, color, pain, and bleeding.
When should you seek dental care?
Arrange prompt assessment for repeated bleeding, a sore that does not settle, a hard edge, pus, fever, increasing pain, or facial swelling. Emergency care is needed if bleeding is heavy or swelling interferes with breathing or swallowing.
What should you ask the dentist?
Ask what tissue is affected and whether a tooth edge, filling, gum pocket, ulcer, or infection explains it. Ask whether the area needs cleaning, smoothing, dental treatment, a sample, or review by another clinician.
Frequently asked questions
Can a sharp tooth create a bleeding sore?
Yes. Repeated rubbing from a sharp tooth, broken filling, or appliance can injure the mouth lining.
Should I cover the sore?
Do not place a dressing or chemical on it; keep it clean and have a persistent or recurrent lesion examined.
