How the BrushTest Works

Step 1: Discover

Small Red or White Spot is Observed

People get white or red spots in their mouths from time to time. The majority of spots are caused by everyday trauma such as cheek biting or pizza burns, but some contain unhealthy cells that if left alone could become a problem. If a spot is observed, and there is no clear cause, it needs to be tested by collecting and analyzing cells.

Step 2: Sample

BrushTest’s Bristles Samples the Spot

The BrushTest is pressed against the spot and turned; collecting thousands of cells. This is necessary because doctors can’t simply look at a spot and know what caused it to appear, or if it has the potential to cause you any harm. The specimen is then sent to the lab for analysis.

Step 3: Analyze

Specimen Analyzed by Pathologists

OralCDx Labs has a special process for analyzing each specimen which makes it very accurate. Our imaging system acts like a spell check for cells that brings potential abnormal cells to the attention of our expert pathologists. Then, our pathologists analyze the specimens and issue a result

Step 4: Diagnose

Findings and
the Result

The report from OralCDx gives the doctor information that helps determine the cause of the spot so that it can be treated. Just like with a pap smear, the expectation is that the result of the BrushTest will be “negative” for precancer or cancer. Even if unhealthy cells are found, the spot can typically be removed before it can become harmful.


It’s important to have an annual Oral Health Exam ( or Oral Cancer Screening) by either a Physician or a Dentist. If you notice something in your mouth that won’t go away, don’t ignore it and don’t wait for your annual visit. Call your Physician or dentist and bring it to their attention so that it can be tested.
