This guide is general education, not a diagnosis or an individual treatment plan. Urgent, severe or worsening symptoms belong with the local emergency service or a qualified clinician.

What this guide covers

Mouth ulcers by pattern and duration. This source-reviewed orientation page separates stable record-the-exact-site-duration-pattern-trigger-exposure-and-change-over-time principles from decisions that depend on examination, probing, imaging, saliva function, medical and medicine history, restoration status, tooth-wear distribution, product concentration, age, local law and an individual dental or medical assessment. The named editions, URLs and reuse limits were checked on 2026-09-10.

It remains outside search indexes pending a second-person clinical editorial review and localisation.

How to use it

Start with the description that most closely matches your question about Mouth ulcers by pattern and duration. Use the evidence section to understand what is known, then use the boundary section to decide when self-education should stop and clinical care should begin.

The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.

Reviewed editorial notes

These concise notes are independently written from the source set below. In an emergency, use the local emergency number and follow the dispatcher rather than relying on a static page.

Track site, number, duration, recurrence and surrounding change

Record the first-seen date, exact oral site, number, size change, pain, bleeding, preceding bite, burn or rough dental edge, recent medicine and whether similar episodes recur. Also note ulcers elsewhere, joint symptoms, fever, weight change or immune problems. Many short-lived ulcers are benign, but appearance alone cannot distinguish trauma, recurrent aphthous ulceration, infection, inflammatory disease, medicine effects or malignancy.

Make the persistent-lesion boundary visible and localise the pathway

NHS patient guidance advises professional review for a mouth ulcer lasting longer than three weeks, and NICE NG12 uses unexplained oral ulceration beyond three weeks in its UK suspected-cancer referral recommendation. This threshold is a safety-net, not a cancer prediction or permission to wait when a lesion is rapidly worsening, bleeding, unusually painful or associated with swallowing, speech, neck-lump or systemic problems. Estonia and Finland pathways and urgency instructions must come from current local services.

Search vocabulary in four languages

Terminology changes across borders. These are example phrases people use for the same subject in Estonian, Finnish, Russian and English; they are included as a practical vocabulary aid, not as hidden keywords.

Reviewed sources and reuse boundaries

Authoritative source editions, URLs, scope and reuse limits were checked on 10 September 2026. The gum, dry-mouth, breath, oral-lesion, tongue, enamel, tooth-wear and whitening notes are independently paraphrased and remain noindex pending second-person dental, oral-medicine, clinical and Estonia/Finland localisation review.

Source URLs and reuse terms checked: 2026-09-10. This date is not a guarantee that an external source has remained unchanged.

Scope and boundaries

This source-review release verifies the named editions, URLs, scope and reuse limits for the orientation page. It remains outside search indexes: it is not a diagnosis, periodontal chart, stage or grade, oral-cancer exclusion, product endorsement, whitening clearance, individual treatment or medicine-change plan, and it cannot replace examination by the person’s own dentist, periodontist, oral-medicine clinician, doctor or pharmacist and current local law.
