Oral Biopsy

A mouth biopsy removes a sample, or a small lesion, so it can be examined under a microscope for the cause of a problem.

[3]

The short answer

An oral biopsy removes a sample from a mouth or facial area, and a laboratory examines it under a microscope to help identify the cause of a problem.

What is an oral biopsy?

The two main biopsy approaches
TypeWhat is removed
IncisionalA small sample is taken while the whole lesion or lump remains.[1][3]
ExcisionalA very small lesion or lump in one part of the mouth is removed completely.[1][3]

[1][3]

Who may need a biopsy?

A biopsy is used when a mouth or facial area looks different and more information is needed before a treatment plan is made, or when a small, localised lesion can be removed in one procedure.

[1][3]

Does it hurt?

The area is usually numbed with a small injection of local anaesthetic. Afterward, discomfort is commonly managed with regular pain relief such as ibuprofen or paracetamol.

[1]

Is it safe?

The listed risks are pain, bleeding, discomfort and swelling, although the risks are described as very small.

[1][2]

How long does it last?

A follow-up appointment may be arranged before you leave. It checks healing and gives the result of the microscope test, while some patients receive results by post.

[1]

What happens during the procedure?

The clinician numbs the site, takes either part of a lesion or removes a small lesion, and sends the sample to a laboratory for microscopic examination.

[1][3]

What is recovery like?

Expect some local discomfort after the biopsy, with pain relief used as needed. A planned review checks that the area is healing and communicates the laboratory result.

What follows the biopsy
StageWhat happens
Immediately afterPain, bleeding, discomfort or swelling can occur.[1][2]
Follow-upHealing is checked and the microscope result is given.[1]

[1][2]

What are the alternatives?

The choice is between sampling a larger or uncertain area with an incisional biopsy and fully removing a very small, localised lesion with an excisional biopsy.

[3]

What should I expect after the biopsy?

The sample goes to a laboratory, and the result is based on examination under a microscope. The clinic may arrange the results appointment before you leave or send the result by post.

[1]

How is an oral biopsy paid for in the UAE?

A price is not specified here. The scope to identify on a quote is the biopsy type, the sample or lesion removed, laboratory examination, and any follow-up result appointment.

[1][3]

Frequently asked questions

Will the whole mouth lesion always be removed?

No. An incisional biopsy removes only a sample when an area is large, affects multiple areas, or needs diagnosis before a full treatment plan.
