ORAL SURGERY

Oral pathology and biopsies

It is important not to ignore any new lump, ulcer, white or red patch in the mouth. This is one of the reasons for regular dental check-ups. Our surgeons will often take small samples of tissue from within the mouth (biopsy) which can then be analysed under a microscope to help diagnosis and subsequent management.

IS THIS FOR YOU?

Referral for an oral biopsy is recommended when:

  • A new lump, ulcer, white patch or red patch in the mouth has persisted for more than two weeks
  • Your dentist or doctor has identified a lesion of uncertain diagnosis
  • An existing lesion has changed in size, colour or texture
  • Imaging or clinical examination raises concern about pathology
  • Tissue analysis is needed to confirm or rule out malignancy

RECOVERY TIMELINE

Recovery timeline

  • 0–1 day

    First 24 hours

    Local discomfort at the biopsy site that settles with simple analgesia. Soft diet, avoid the biopsy area when brushing, and rinse gently as instructed.

    Red flags · Heavy bleeding not slowed by gentle pressure, or rapid swelling.

  • 1–7 days

    Day 2–7

    The biopsy site heals over several days. Dissolvable sutures fall away. Most patients return to normal activity within 24 to 48 hours.

  • 7–14 days

    Week 1–2

    Histopathology results are usually available within 1 to 2 weeks and will be discussed at your follow-up appointment, with onward management planned where required.

RISKS & HONESTY

Risks we discuss before consent

  • Bleeding and bruising

    Some bleeding at the biopsy site is normal; firm pressure with gauze controls it. Bruising of the surrounding tissue may occur.

  • Discomfort and altered taste

    Local soreness for a few days is usual, particularly for biopsies on the tongue or floor of mouth. Altered taste at the site may occur transiently.

  • Infection

    Infection of the biopsy site is uncommon and is treated with prescribed antibiotics where it occurs. Persistent swelling or fever warrants review.

  • Diagnostic limitation

    Occasionally a repeat or larger biopsy is required if the initial sample is not diagnostic, particularly for very small or deep lesions.

FREQUENTLY ASKED

Common questions about oral biopsies

What happens at an oral biopsy appointment?

Most biopsies are performed under local anaesthesia in clinic. The surgeon numbs the area, removes a small sample of tissue (or, where appropriate, the whole lesion), and closes the site with dissolvable sutures. The tissue is sent to a pathologist for analysis under a microscope. The whole appointment usually takes 30 to 60 minutes including consent and aftercare instructions.

When will I get the results?

Histopathology results are usually available within 1 to 2 weeks and will be discussed with you at your follow-up appointment. Where the result requires urgent onward referral or treatment we will contact you sooner.

Will I need any further treatment after the biopsy?

This depends entirely on the diagnosis. Many lesions are benign and require no further treatment. Where the biopsy identifies a lesion needing definitive excision, ongoing surveillance, or referral to another specialist, we will coordinate that pathway with you and with your dentist or GP.

Should my dentist do this, or do I need a specialist?

Many general dentists are comfortable with simple excisional biopsies of straightforward lesions. Referral to an oral and maxillofacial surgeon is appropriate when the lesion is difficult to access, of uncertain diagnosis, near vital structures, or when malignancy needs to be excluded with definitive surgical management.
