A Mouth Ulcer or Patch That Is Not Healing

A persistent mouth change deserves an examination. An ulcer or patch does not automatically mean cancer, but appearance alone cannot establish its cause.

When to Seek Help

Arrange an examination if a mouth sore, irritation or patch lasts more than two weeks. Seek advice sooner for a growing lump, unexplained bleeding, numbness or difficulty swallowing. Breathing difficulty needs immediate hospital care.

Changes Worth Mentioning

Tell the dentist about a persistent sore, thickened area, red or white patch, a neck lump, or difficulty moving the tongue or jaw. Also mention unexplained pain, bleeding or a change in how dentures fit. Do not wait for a lesion to become painful before seeking help.

Make a Short Record

Note when you first noticed the change, its location and whether it has altered. A dated photograph may help explain the history, but cannot replace an examination. Bring a list of medicines and tell the clinician about tobacco, alcohol or areca-nut use.

What Happens at the Appointment?

The clinician asks about the history and examines your mouth. Depending on the findings, the next step may be addressing irritation, a planned review or referral for further review, which can include a biopsy. Ask exactly when to return and what change should prompt an earlier call.

Questions About Your Next Step

Does a Persistent Ulcer Mean Cancer?

No. Several conditions can cause mouth changes. An examination, and sometimes further testing, is needed to understand the cause.

Can I Send a Photograph Instead?

A photograph can help you describe what you noticed. It cannot rule out a serious cause or show everything a clinician needs to examine. Book a consultation for a persistent change.
