Have a sore on my gum
A gum sore may be an ulcer, injury, irritation, or dental infection, and its appearance and duration guide the next step.
The short answer
A sore on the gum is a symptom rather than a diagnosis and may be caused by trauma, an ulcer, a sharp tooth, a denture, or infection.
What does a gum sore show before diagnosis?
The symptom or concern is a visible finding rather than a complete diagnosis. Its location, timing, appearance, and related symptoms help the dentist distinguish irritation, inflammation, infection, or tooth-related causes.
What can you do while monitoring a gum sore?
Avoid rubbing the area, use a soft brush, and note when it began.
When does a gum sore need dental assessment?
Seek care if it has not healed within two weeks, keeps returning, grows, or comes with fever or facial swelling.
What should you ask about identifying the gum sore?
Ask what feature identifies the sore, whether a tooth is responsible, and what examination is needed if it does not resolve.
Frequently asked questions
Can I manage this only at home?
Home care may reduce irritation, but persistent, worsening, or painful symptoms need an examination to identify the cause.
What happens at the first visit?
The dentist inspects the area, asks about timing and symptoms, and performs focused tests before recommending treatment.
