A KEY QUESTION
Book local care for an unexplained mouth change. A photograph cannot replace examination or necessary tests.
What the dentist checks
The examination can include the mouth, lips and neck. You may be asked to move your tongue or head so the clinician can see different areas. Mention soreness, bleeding, altered sensation, a lump or difficulty speaking or swallowing, including concerns hidden beneath a denture.

Describe the change
Note when it started, whether it healed and returned, and how it has changed. Mention rubbing, injuries or recent dental work without assuming the cause. Share relevant health and medicine information. Avoid poking, scraping or applying unadvised products to test the area.
Limits of photographs
A dated photograph may help show changes, but lighting and angles can hide details. It cannot replace examining and feeling tissues. Have the finding explained and establish whether it needs review or referral. “Lesion” simply means an area of change; it is not a diagnosis.
When to arrange care
Ask for urgent dental advice if a mouth ulcer has been present for two weeks or more and is not healing or has become worse. Contact a dentist or NHS 111 in England rather than waiting for three weeks. Any ulcer lasting over three weeks needs a dentist or GP check. Unexplained red or white patches, lumps, persistent pain or difficulty speaking or swallowing also need assessment without waiting. A lump or patch that is growing or not going away needs urgent advice. These changes can have causes other than cancer.
Swelling that affects breathing or swallowing needs immediate emergency help. In the UK, call 999.
Reviews and referrals
If an area needs monitoring, agree when it will be checked and which changes need earlier contact. For a referral, establish the service, booking arrangements and who explains results. Follow up if appointment details do not arrive. Further investigation, including biopsy, does not itself confirm cancer.
Before elective dental work
Tell the treating dentist about unresolved changes, pending appointments or test results before agreeing to elective care. Keep relevant letters and results available. An overseas treatment enquiry should not delay local investigation or be treated as remote screening.
