A biopsy is a common oral surgery procedure in which a small sample of tissue is carefully removed from an area of concern in the mouth, gums, jaw, or surrounding tissues for further examination. Biopsies are performed to help diagnose abnormalities such as unusual growths, persistent sores, cysts, lesions, or changes in tissue that may require closer evaluation. The tissue sample is sent to a specialized laboratory where it is examined under a microscope to determine the nature of the condition and guide any necessary treatment. Oral surgeons are specially trained to perform biopsies safely and comfortably while prioritizing accurate diagnosis and patient care.
