An oral biopsy is a dental or medical procedure used to diagnose abnormal tissue changes in the mouth. During the procedure, a dentist, oral surgeon, or specialist removes a small sample of tissue from an area that appears unusual or suspicious. The sample is then sent to a laboratory where a pathologist examines it under a microscope.
Oral biopsies are often performed to evaluate persistent sores, lumps, patches, or other abnormal changes in the mouth that do not heal or respond to routine treatment. The results can help identify conditions such as infections, benign growths, inflammatory diseases, or oral cancer. By analyzing the tissue sample, clinicians can determine the cause of the abnormality and guide appropriate treatment.
