An ulcer that lasts more than three weeks
The NHS advises seeing a GP or dentist if a mouth ulcer lasts longer than three weeks, keeps coming back, or becomes more painful and red. Most ulcers heal within a week or two.

Oral Biopsy Dubai: What Happens When a Sore, Patch or Lump Is Tested
Most mouth sores are harmless and heal within two weeks. When one does not, or a patch or lump appears, a small tissue sample is the only way to know what it is.

Quick answer
What is an oral biopsy and when is it needed?
An oral biopsy is a minor procedure in which a small piece of tissue is taken from a sore, patch or lump in the mouth, under local anaesthetic, and examined by a pathologist. It is considered when a mouth ulcer lasts more than three weeks, a white or red patch will not rub off, or a lump has no clear cause. At Creative Arts in Dubai, Dr. Firas Osman assesses the area and explains whether a biopsy is needed.

When to get checked
When does a mouth sore need a biopsy?
Looking alone cannot tell a harmless patch from a worrying one. These are the signs that make a dentist or surgeon think about testing tissue.
A white or red patch that will not rub off
A white patch that cannot be scraped away (leukoplakia) or a red, velvety patch needs a diagnosis. Causes such as thrush or cheek biting are ruled out first.
A lump with no clear cause
A swelling on the gum, tongue, cheek, palate or lip that does not settle once an obvious cause, such as an infected tooth, has been treated.
A lesion that is changing
Growing, bleeding, hardening, or a new numbness of the lip or tongue nearby. Any change in a known patch is worth a prompt look.
Why a biopsy, and not just a look?
Many conditions look alike in the mouth. A white patch can be harmless thickening from friction, a fungal infection, an inflammatory condition such as lichen planus, or, less often, an area with abnormal cells. The NHS notes that leukoplakia carries a small chance of turning into mouth cancer over time, and that a dentist or GP may refer for a biopsy. The NHS also lists a biopsy among the tests used to diagnose mouth cancer.
Most biopsies show something benign, but only a pathologist looking at the cells under a microscope can say so with confidence. Waiting months to see whether something goes away is the step to avoid. If you are unsure whether a patch needs attention, our guide to white tongue and white patches and our page on a lump on the gum or palate explain the common causes.
Types of biopsy
Which kind of oral biopsy might you have?
The surgeon chooses the approach from the size, site and appearance of the area.
| Type | What is removed | Usually chosen when |
|---|---|---|
| Excisional biopsy | The whole lesion with a small margin of normal tissue | The area is small and looks benign, such as a fibrous lump or a small blister-like swelling of the lip |
| Incisional biopsy | A representative piece of a larger area | The patch or ulcer is too large to remove in one go, or a diagnosis is needed before planning treatment |
| Punch biopsy | A small round core of tissue | A flat patch where a neat sample of the surface and the layer beneath is enough |
| Brush test | Surface cells collected with a small brush | Sometimes used as an extra aid; it does not replace a tissue biopsy when a lesion is suspicious |
Bone lesions and jaw cysts are a different procedure; see jaw cyst removal.
Step by step
What happens during an oral biopsy?
A soft-tissue biopsy is a short, minor procedure. You are awake and can usually go back to normal activities the same day.
Examination and history
How long the area has been there, whether it has changed, smoking, shisha or dokha use, medicines and general health.
AssessmentWritten plan
Whether a biopsy is needed, which type, what it involves and any alternatives such as a short review period, explained before anything is done.
Before the procedureLocal anaesthetic
The area is numbed with an injection. You may feel pressure during the procedure but should not feel sharp pain; tell the surgeon if you do.
ProcedureTaking the sample
A small piece of tissue, or the whole small lesion, is removed and placed in a labelled container for the laboratory.
ProcedureClosing the area
A few stitches, usually dissolvable, close the site. Bleeding is controlled with pressure before you leave.
ProcedureResults review
The report is explained to you in person, with the next steps in writing.
Results appointment
After the biopsy
Does an oral biopsy hurt, and how long do results take?
The procedure itself is done under local anaesthetic. Afterwards the site is usually sore for a few days, much like a mouth ulcer, and discomfort is usually managed with over-the-counter pain relief as directed on the label or by your pharmacist. Soft, lukewarm food, gentle salt-water rinses from the next day and avoiding smoking help it heal. Stitches, if used, typically dissolve within about one to two weeks; our guide to stitches in the mouth explains what to expect.
The sample goes to a histopathology laboratory, where a pathologist prepares and examines it. This is a medical pathology laboratory, not the dental laboratory in our building, which makes crowns and veneers. Results commonly take a week or two, and longer if special tests are needed. You are told the expected timing when the sample is sent and are given an appointment to discuss the report.
What if the result is abnormal?
Pathology reports fall into a few broad groups, and each leads somewhere different:
- Benign: for example a fibrous lump from cheek biting, or a mucocele. If the whole lesion was removed, usually nothing more is needed apart from avoiding the cause.
- Inflammatory or immune conditions: such as lichen planus. These are managed and monitored, sometimes together with your doctor.
- Dysplasia: changes in the cells that are not cancer but can carry a higher risk over time. Management depends on the grade and may include removal of the area and regular review.
- Cancer: you are referred promptly to a hospital head-and-neck team for further tests and treatment. Creative Arts does not provide cancer treatment, but stays in contact for your dental care.
When a lesion looks strongly suspicious or lies in a difficult site, Dr. Firas Osman may refer you directly to a hospital team for the biopsy and imaging, so there is no delay. Reducing tobacco, shisha, dokha and alcohol use lowers the risk of new patches; our guide to oral cancer screening explains how the mouth is checked at routine visits.
Do not wait to see if it goes away
Book an assessment if any sore, patch or lump in your mouth has lasted more than three weeks, even if it does not hurt. The clinic is open daily 10:00–20:00. Go to a hospital emergency department if you have rapidly increasing swelling, difficulty breathing or swallowing, or bleeding that will not stop with pressure.
Planning
What affects the plan and cost of an oral biopsy?
No fees are listed online. Your written plan sets out what is included before anything is done.
- Size and siteA small lump on the lip is simpler than a larger patch on the tongue or floor of the mouth.
- Type of biopsyRemoving a whole small lesion differs from sampling part of a larger area, and some cases need more than one sample.
- Laboratory examinationThe pathology report, and any special tests the pathologist needs, are part of the overall cost.
- Imaging and reviewSome lumps need an X-ray or a CBCT 3D scan first, and every biopsy needs a results appointment.

Patient questions
Frequently asked questions
When does a mouth sore need a biopsy?
When an ulcer lasts more than three weeks, a white or red patch cannot be rubbed away, a lump has no clear cause, or a known area starts to change, bleed or harden. Most sores heal within one to two weeks. A dentist first rules out simple causes such as a sharp tooth or cheek biting before suggesting a biopsy.
Does an oral biopsy hurt?
The area is numbed with local anaesthetic, so you should feel pressure rather than sharp pain during the procedure. Afterwards it is usually sore for a few days, similar to a mouth ulcer. Soft food, gentle salt-water rinses from the next day and over-the-counter pain relief used as directed on the label usually keep it comfortable.
How long do oral biopsy results take in Dubai?
Commonly about one to two weeks, depending on the pathology laboratory and whether special tests are needed. You are told the expected timing when the sample is sent, and the report is explained to you at a results appointment rather than left to read alone, with the next steps given in writing.
What happens if the oral biopsy result is abnormal?
It depends on the finding. Benign lesions often need nothing further. Inflammatory conditions are monitored and managed. Dysplasia, meaning abnormal but not cancerous cells, may need removal and regular review. If cancer is found, you are referred promptly to a hospital head-and-neck team, and the clinic stays in contact for your dental care.
Does a biopsy mean the dentist thinks it is cancer?
No. A biopsy is the standard way to get a definite diagnosis for any persistent sore, patch or lump, and most results are benign. It is recommended because several harmless and less harmless conditions look the same to the eye. Testing early is simply more reliable, and more reassuring, than waiting to see.
Can I eat normally after an oral biopsy?
Once the numbness has worn off, yes, but choose soft, lukewarm food for a few days and chew away from the site. Avoid very spicy, salty, acidic or crunchy food until it has settled, and avoid smoking, which slows healing. Gentle salt-water rinses from the next day keep the area clean.
