When you visit our office for an evaluation, we complete an Oral Cancer Screening to make certain there is no Oral Pathology present involving your gum tissues, tongue, cheeks, lips, palate, etc.  If during the examination we find any abnormalities, we may suggest a biopsy to make certain there is no harmful pathologic process present.

A biopsy is a diagnostic procedure during which Dr. Kobernick removes a tissue sample (incisional biopsy) or all of the abnormal tissue (excisional biopsy).  The tissue is submitted to a Pathologist to be examined under a microscope.  Early detection and treatment of a lesion which proves to be malignant provides a better chance for cure.  

Abnormal results could represent:

  • Oral Cancer:  The most common causes for oral cancer are tobacco use and excessive alcohol consumption.  Other causes include poor oral hygiene, irritation caused by ill-fitting dentures and rough surfaces on teeth, poor nutrition, or they may be caused by an unknown etiology.
  • Non-cancerous mouth sores that may require no treatment.


After using topical (gel) anesthetic, local anesthetic is gently applied to the questionable tissue area to ensure the biopsy is painless. The abnormal tissue, or a small piece of it, is removed.  The biopsy often leaves a small tissue opening which requires the use of dissolvable stitches for closure.  After the numbness wears off, the site maybe sore for a few days.  Often Tylenol or Ibuprofen is adequate to relieve any discomfort. Most people are able to return to work later the same day.  The site usually heals rapidly, typically feeling normal within one week.

The biopsied tissue is sent to a Pathologist for microscopic evaluation.  The biopsy report created by the Pathologist not only helps to establish a diagnosis, but it also enables us to develop a specific plan of treatment (when that is necessary). We recommend a monthly self-examination, looking for the following signs which may represent a pathologic process or cancerous growth

  • Reddish Patches (Erythroplasia)
  • Whitish Patches (Leukoplakia)
  • A sore that fails to heal and bleeds easily
  • A lump or thickening of the tissues of the mouth
  • A mass or lump in the neck
  • Chronic sore throat or hoarseness
  • Difficulty in swallowing
