Part of your routine dental visit is a cancer screening test. Dentists and dental hygienists look at your mouth, tongue, and nearby tissue much more closely than you can. They can find pre-cancerous or cancerous spots in the early stages of growth. Cancer of the mouth is called oral cancer.

How do dentists check for oral cancer?

During your oral cancer screening exam, your dentist will look at and feel your face, neck, lips, mouth, tongue, thyroid gland, salivary glands, and lymph nodes. If you have dentures or partials, they should be taken out so that your whole mouth can be checked.

  • A lump, thickening, rough spot, crust, or small eroded (worn away) area.
