Oral cancer screenings are important preventive examinations that help detect early signs of cancer or abnormal tissue changes in the mouth. Early detection plays a critical role in successfully treating oral cancer and improving patient outcomes. During an oral cancer screening, the dentist carefully examines the mouth, lips, tongue, throat, and surrounding tissues for any unusual lumps, sores, discoloration, or abnormalities.

The screening is quick, painless, and usually performed as part of a routine dental exam. Dentists visually inspect the oral tissues and may gently feel the neck, jaw, and throat areas to check for any swelling or unusual growths. In some cases, special lights or screening tools may be used to help identify abnormal cells that are not easily visible.
