​​​​​​​Oral Pathology/Biopsies

Unusual changes in your mouth are easy to dismiss — a persistent sore, a white patch, a lump that comes and goes. But the mouth is one of the most accessible areas of the body for early disease detection, and changes to the soft tissue lining can be among the earliest signals of a developing condition. Oral pathology is the field focused on identifying and treating diseases of the mouth, jaw, and surrounding structures. Some of these conditions are benign and easily managed, while others, including oral cancer, require prompt evaluation to protect your long-term health. According to the National Institute of Dental and Craniofacial Research, the five-year survival rate for localized oral cancer is approximately 86% — compared to around 40% when the disease has spread — making early diagnosis one of the most meaningful factors in outcome.

At Wilshire Oral Surgery and Implant Center, our board-certified oral and maxillofacial surgeons Dr. Saman Vahedi and Dr. Jonathan Shadi provide thorough oral pathology evaluations, biopsies, and individualized treatment for patients throughout West Los Angeles. Dr. Vahedi is a Diplomate of the American Board of Oral and Maxillofacial Surgeons, and Dr. Shadi completed his residency at UC San Francisco-Fresno. We use advanced cone beam 3D imaging and the latest diagnostic technologies to assess abnormal tissues accurately, and we approach every case with the same commitment: deliver a clear diagnosis, explain your options honestly, and develop a treatment plan you feel confident in.

What is Oral Pathology?

Oral pathology is the specialty of dentistry and medicine focused on diagnosing and treating diseases that affect the oral and maxillofacial region. This includes the lips, tongue, cheeks, palate, gums, jaw, salivary glands, and the head and neck. Conditions range from common infections and benign cysts to autoimmune disorders and malignancies.

The soft tissue lining of your mouth — the mucosa — normally appears smooth and coral pink in color and texture. Any alteration to that appearance, whether a color change, rough patch, lump, or persistent sore, may signal the beginning of a pathological process. These changes are not always painful, which is exactly why professional evaluation matters. Waiting for discomfort to prompt a visit can allow a condition to progress past its most treatable stage.

Oral and maxillofacial surgeons receive extensive training in oral pathology and are among the most qualified providers to evaluate, diagnose, and manage these conditions. Our team at Wilshire Oral Surgery and Implant Center manages a broad range of oral diseases and abnormalities, from infections and cysts to bone grafting-related pathology and oral cancer.

Conditions We Evaluate and Treat

We regularly see a wide range of oral pathology conditions in our West Los Angeles office. Common conditions include:
Oral Cancer
The most serious oral pathology condition — requires biopsy for definitive diagnosis and may involve surgical treatment, radiation, or oncology coordination.
Cysts and Benign Tumors
Fluid-filled sacs or growths in soft tissue or bone. Often asymptomatic until detected on imaging. Typically removed surgically.
Salivary Gland Disease
Infections, blockages, or tumors of the salivary glands — often presenting as swelling, pain, or dry mouth.
Bacterial and Viral Infections
Including herpes simplex, candidiasis (thrush), and other oral infections requiring targeted medical management.
Autoimmune Disorders
Conditions such as pemphigus, erosive lichen planus, and mucous membrane pemphigoid that affect the oral lining and require specialist evaluation.
Soft and Hard Tissue Lesions
Abnormalities in the gums, cheeks, tongue, or bone — including leukoplakia, erythroplakia, and fibromas — that require evaluation to determine whether they are benign or precancerous.
Early evaluation of any of these conditions leads to more straightforward treatment and significantly better outcomes.

Signs to Watch For

We recommend that all patients perform regular oral self-examinations between dental visits. Stand in front of a mirror with good lighting and check the inside of your cheeks, the roof of your mouth, your gums, the floor of the mouth under your tongue, and the sides and underside of your tongue. There may not always be pain or discomfort, which makes self-examination and routine professional screening essential.

Contact our office promptly if you notice any of the following:

  • White or red patches inside your mouth that do not resolve within two weeks
  • A sore that bleeds easily or fails to heal on its own
  • Lumps, thickened areas, or rough patches on any soft tissue surface
  • Persistent hoarseness, sore throat, or unexplained voice changes
  • Numbness or pain in the mouth, lips, or tongue
  • Difficulty chewing, swallowing, or speaking
  • A lump or mass in the neck

These signs do not always indicate cancer, but they must be evaluated promptly to determine their cause. Identifying a pathological process at an early stage dramatically increases the range of treatment options available and the likelihood of a straightforward outcome.

When a Biopsy Is Needed

A biopsy is the most reliable method for definitively diagnosing a suspicious oral lesion. During a biopsy, a small tissue sample is removed from the affected area under local anesthesia and sent to a pathology laboratory, where it is analyzed microscopically for signs of disease, precancerous changes, or malignancy. The procedure is typically straightforward, takes only a few minutes, and causes minimal discomfort.
1
Evaluation
Your surgeon reviews your health history, performs a clinical exam, and uses 3D imaging to assess the area of concern.
2
Sample Collection
The area is numbed with local anesthesia. A small tissue sample is removed carefully and sent to a pathology lab for analysis.
3
Pathology Report
The lab provides a definitive diagnosis. Your surgeon reviews the findings with you in detail before any treatment decisions are made.
4
Individualized Treatment
Treatment is tailored to the diagnosis — from monitoring and medication to surgery, reconstruction, or oncology coordination.
Our surgeons recommend a biopsy when a lesion has not resolved after two to three weeks, when a patch or sore appears suspicious in color or texture, or when a patient has known risk factors including tobacco use, heavy alcohol consumption, or HPV. For patients who prefer a more comfortable experience, we offer IV sedation and general anesthesia options in addition to standard local anesthesia.

Treatment for Oral Pathology Conditions

Treatment for oral diseases is highly individualized and depends entirely on the diagnosis. Mild bacterial infections may respond to a course of antibiotics. Fungal infections such as candidiasis are managed with antifungal medication. Benign cysts and growths are typically removed with a minor outpatient procedure using the techniques needed to minimize disruption to surrounding tissue. More serious diagnoses, including oral cancer or complex lesions, may involve reconstructive surgery, coordination with a medical oncologist, radiation therapy, or a combination. Our surgeons are trained in reconstructive oral and maxillofacial surgery and work closely with referring providers to ensure continuity of care throughout treatment. No matter what the biopsy reveals, our approach remains the same: an honest explanation of findings, a clear set of options, and a treatment plan developed around your specific situation.
