Oral Biopsy in San Jose, CA
 If your dentist found something in your mouth that didn’t look right and recommended an oral biopsy in San Jose, CA, South Valley Oral and Facial Surgery performs the procedure with the surgical precision and pathology coordination that diagnostic accuracy requires.
An oral biopsy is a brief procedure in which a small piece of tissue is removed from your mouth and sent to a pathology lab for analysis. Being told you need a biopsy is unsettling, and our team treats every patient as someone with a real, valid concern.
Our two board-certified oral and maxillofacial surgeons regularly receive biopsy referrals from general dentists, hygienists, and physicians throughout our San Jose, Gilroy, and Los Banos offices. We perform the biopsy itself, coordinate directly with the pathology lab, and walk you through the results when they come back. If treatment is needed afterward, you stay with the same surgical team rather than being passed to another office. Many biopsies happen alongside a broader oral pathology evaluation of any other areas of concern.
Most oral biopsies are quick, performed under local anesthesia, and produce results that resolve uncertainty far more often than they confirm a worst-case diagnosis. A biopsy is a diagnostic step, not a verdict.

What Is an Oral Biopsy?
 An oral biopsy is the surgical removal of a small tissue sample from inside your mouth, which is then examined under a microscope by a pathologist. The microscopic analysis is what makes the diagnosis definitive. Looking at a lesion in the mouth, even with experienced eyes, can only narrow the possibilities. Only laboratory analysis of the tissue itself confirms what a spot, patch, or lump actually is.
Biopsies are typically recommended for any oral lesion that has not resolved in two to three weeks, for white or red patches without an obvious cause, for any palpable lump in the cheek, tongue, gums, or floor of the mouth, and for tissue that bleeds, ulcerates, or changes appearance without explanation. A biopsy may also be recommended when imaging reveals something inside the jaw that needs identification. Many of these findings turn out to be benign. We perform biopsies precisely so you don’t have to live with uncertainty.
Types of Oral Biopsy
There are three main types of oral biopsy, and the right one depends on the size, location, and appearance of what is being sampled.
| • |
Incisional Biopsy – A small portion of a larger lesion is removed for analysis. We use this when the area in question is too big to remove entirely in one step, or when removing the whole lesion would require a more involved procedure that should wait until the diagnosis is confirmed.
|
| • |
Excisional Biopsy – The entire lesion is removed in one procedure, along with a small margin of healthy tissue. This is often used for smaller, well-defined lesions and can serve as both the diagnostic step and the treatment in one visit.
|
| • |
Brush Biopsy – A small brush collects surface cells from a suspicious area without making an incision. Brush biopsies are useful as a screening-level step when a sample is needed but a full surgical biopsy isn’t yet warranted. |
Our surgeons select the biopsy type based on what gives the pathologist the best possible sample with the least disruption to surrounding tissue. That decision is made during your consultation, after we examine the area and review any imaging your referring dentist or physician sent over.
When a Biopsy Is Recommended
Common reasons your dentist or physician may refer you for an oral biopsy include a sore that hasn’t healed after a few weeks, a white or red patch on the tongue or cheek that doesn’t wipe away, a lump or thickening in the gum or palate, persistent unexplained bleeding from a specific spot, or a finding from a routine oral cancer screening that needs further definition. Sometimes the referring provider already suspects what the lesion is and wants confirmation. Other times the goal is purely to rule out something serious.
Your Oral Biopsy Surgeons in San Jose
Dr. Joseph McMurray, DMD, MBA, FACOMS is a board-certified oral and maxillofacial surgeon with more than 35 years of surgical experience and 11 years of service in the U.S. Navy, including time as fleet oral surgeon aboard the USS Nimitz and as clinical department head at U.S. Naval Hospital in Naples, Italy. Full background on Dr. McMurray’s bio.
Dr. Arian Chehrehsa, DDS, ABOMS, NDBA is dual board-certified in both Oral & Maxillofacial Surgery and Anesthesiology. San Jose-born and locally trained through Leland High School and Santa Clara University, he completed his oral surgery residency at Montefiore Medical Center in New York before returning home to practice. More on Dr. Chehrehsa’s bio.
Both surgeons routinely perform oral biopsies as part of our broader pathology scope, including evaluation and surgical management of oral cysts and tumors when needed. Because they are board-certified surgeons rather than general dentists, they can move directly from diagnosis to definitive treatment if the pathology report calls for it. That continuity matters; you don’t want to be re-referred to a third specialist mid-process if anything is found.
What to Expect, Step by Step
Most patients are in and out in under an hour.
Consultation and Clinical Exam
We begin by examining the area your dentist or physician flagged, reviewing any photos or imaging that came with the referral, and asking about symptoms and history. When the case is complex or the lesion sits in a difficult location, both surgeons review the imaging together before we settle on the sampling approach. This planning detail is part of why our biopsy specimens come back as clear, diagnostically useful samples.
Local Anesthesia (and Sedation If Needed)
We fully numb the area with local anesthesia before removing any tissue. Most patients feel a brief pinch from the anesthetic, then nothing during the biopsy itself. For patients with significant anxiety or for biopsies in sensitive locations, Dr. Chehrehsa is dual board-certified in anesthesiology, so we deliver IV sedation in-house without bringing in a separate anesthesia team. That keeps both the cost and the scheduling simpler.
Tissue Sampling
We remove the tissue sample using the technique appropriate for the lesion. For most biopsies, this takes only a few minutes. We control any bleeding with gentle pressure and, when needed, close the site with one or two small dissolvable sutures. Brush and surface biopsies involve no incision or sutures at all.
Laboratory Analysis
We send the sample to one of the regional oral pathology labs we have long-standing relationships with. Most reports come back in roughly one to two weeks, though more complex specimens occasionally take longer. When something on a report is unusual or borderline, we call the pathologist directly rather than waiting for clarification by mail. We don’t control the lab’s pace, but we follow up the moment results arrive.
Results and Next Steps
You return for a brief visit to discuss the report. If the result is benign, that’s usually the end of it. If the result calls for further treatment, we either perform that treatment in-house at the same San Jose office or coordinate with the appropriate specialist. We will not leave you wondering what comes next; the plan is part of the appointment.
Why a Biopsy Helps You
 A biopsy is the only way to get a definitive answer about what an unexplained spot, lump, or patch in your mouth actually is. At South Valley Oral and Facial Surgery, you get that answer faster because both of our surgeons review your case together when anything looks ambiguous, and our long-standing relationships with regional pathology labs let us call directly to clarify a report rather than waiting on a written addendum.
The primary benefit is diagnostic clarity. Pathology results either confirm a benign condition that needs no further action, identify a precancerous change that can be addressed before it progresses, or detect cancer at a stage when treatment outcomes are far better than later detection. Because Dr. Chehrehsa is dual board-certified in oral surgery and anesthesiology, any additional sedation needed for an anxious patient happens in-house rather than involving a separate office or anesthesiologist.
The second benefit is continuity. If the report calls for follow-up surgery, we handle it at the same office with the same team that performed the biopsy. You don’t start over with a new specialist when results require action. Across our San Jose, Gilroy, and Los Banos offices, that continuity often shortens the time from biopsy to definitive treatment by weeks compared with multi-office workflows.
For lesions that turn out to be benign but bothersome, an excisional biopsy serves double duty: the same procedure that confirms the diagnosis also removes the lesion entirely.
Why Choose Our Team for Your Biopsy
A biopsy is a small procedure with big implications, and the surgeon performing it matters more than people often realize. The sampling technique, the choice of biopsy type, and the way the specimen is handed off to the pathology lab all affect whether the result comes back clear and actionable or ambiguous.
Our team has been performing oral biopsies in San Jose for decades. Dr. McMurray and Dr. Chehrehsa work directly with established oral pathology labs and have long-standing relationships with the pathologists who interpret these samples. When something on a report is unusual or borderline, we can pick up the phone and talk through it, which gets you a more useful answer faster.
If the pathology report identifies something that requires surgical follow-up, both surgeons are equipped to handle the next steps in-house, including excision of larger lesions, surgical management of jaw cysts and tumors, and coordination with medical oncology when needed. Most patients never need that continuation. Having it available matters when you do.
We also see patients who come in for a second opinion oral surgery consultation before deciding whether to proceed with a biopsy at all. We are happy to provide that without pressure.
Cost and Insurance for Oral Biopsy
Cost is a fair concern, and we want to be straight with you. The cost of an oral biopsy depends on the type of biopsy needed, whether any sedation beyond local anesthesia is used, and the pathology lab’s separate fee for analyzing the specimen. The lab fee is billed separately from our surgical fee, and we tell you about both before the procedure.
Most medical and dental insurance plans cover oral biopsies because they are diagnostic procedures, and coverage often comes through medical benefits rather than dental, particularly when the biopsy is performed to rule out cancer. Our front office verifies your specific benefits in advance so you know what to expect. Our insurance and financing details cover accepted plans and CareCredit financing.
If cost is a barrier to moving forward with a recommended biopsy, please tell us at the consultation. We routinely help patients sequence diagnosis and treatment in ways that fit their situation.

Frequently Asked Questions
Does an oral biopsy hurt?
The biopsy itself does not hurt. The area is fully numbed with local anesthesia before any tissue is removed, and most patients feel only a brief pinch from the anesthetic injection. Afterward, mild soreness for a day or two is common, similar to having a small canker sore, and is usually managed with over-the-counter pain relief.
How long does it take to get oral biopsy results in San Jose?
Most oral biopsy results come back from the pathology lab within roughly one to two weeks, depending on specimen complexity and the lab’s current workload. Specialized stains or additional studies can extend the timeline. We do not control the lab’s pace, but we contact you the same day results arrive at our office.
Will I have stitches after my biopsy?
Most incisional and excisional biopsies close with one or two small dissolvable sutures that disappear on their own over one to two weeks. Brush biopsies and superficial samples require no incision and no sutures. Either way, the site sits inside the mouth and is not visible from the outside.
Why do I need an oral surgeon and not my regular dentist for this?
Many general dentists refer biopsies to an oral and maxillofacial surgeon because we perform these procedures regularly, work directly with oral pathology labs, and are equipped to handle any surgical follow-up if the report calls for it. If you’re unsure whether to proceed with a biopsy at all, our second opinion oral surgery consultations are designed for exactly that situation. If the result requires further treatment, you stay with the same surgical team rather than starting over with a new referral chain.
What if my biopsy comes back positive for cancer?
If the pathology report identifies cancer or a precancerous change, we meet with you to explain exactly what was found, what the staging looks like, and what the treatment options are. Depending on the diagnosis, we may handle the next surgical step in-house at South Valley Oral and Facial Surgery or coordinate with medical and radiation oncology specialists. Catching oral cancer at the biopsy stage often means substantially better outcomes than later detection.
Are most oral biopsies cancerous?
No. Most oral biopsies turn out to be benign findings: irritation from a sharp tooth or denture, a non-cancerous growth, or a treatable inflammatory condition. A biopsy is recommended whenever a lesion needs a definitive answer, not because the surgeon already suspects cancer. The purpose is to resolve uncertainty either way.
Does dental insurance cover an oral biopsy?
Most insurance plans cover oral biopsies because they are diagnostic. Coverage often comes from medical benefits rather than dental, particularly when the biopsy rules out cancer. We verify your specific benefits before the procedure so there are no surprises, and our insurance and financing details cover accepted plans.
How long should I wait before getting a biopsy on a sore that won’t heal?
The standard guideline is two to three weeks. Most ordinary mouth sores and ulcers heal on their own within that window. If a sore, patch, or lump persists beyond three weeks, that is the signal to have it evaluated and, if appropriate, biopsied. Waiting longer rarely makes the situation easier, and earlier sampling produces better outcomes if anything is found. |
