White mouth ulcer on gum
A white gum ulcer is often a shallow mucosal break with a pale coating, but a persistent or unusual lesion needs examination.
The short answer
An ulcer is a surface loss in the oral lining, often covered by white or yellow fibrin. Biting, burns, sharp teeth, appliances, and aphthous ulcers are possible causes.
What is the direct answer?
What does this question mean?
Do not pick it; use a soft brush and avoid spicy, acidic, or rough foods while it heals. A dentist can remove an irritating edge and select treatment after diagnosis.
What can you do next?
Seek care if it lasts beyond two weeks, recurs, is hard or raised, bleeds, or comes with numbness, a neck lump, or swallowing difficulty.
When should you seek dental care?
Ask whether it is an ulcer, thrush, trauma, or another lesion, and whether a tooth, denture, medicine, or medical condition is contributing.
Frequently asked questions
What happens at a dental appointment?
The dentist reviews the history, examines the mouth, and uses targeted tests such as probing, photographs, or an X-ray when indicated.
Can I wait and see?
Observation may suit a mild improving symptom, but persistence or worsening warrants an examination.
