Oral cancer screenings are preventive examinations that help detect early signs of cancer or abnormal tissue changes in the mouth. Early detection is extremely important because it significantly increases the chances of successful treatment and recovery. During an oral cancer screening, the dentist carefully examines the lips, tongue, cheeks, gums, throat, and other oral tissues for unusual lumps, sores, or discoloration.

The screening process is quick, painless, and usually performed during a routine dental checkup. The dentist visually inspects the mouth and may gently feel the neck, jaw, and throat areas to check for swelling or unusual growths. In some cases, specialized lights or screening tools may be used to help identify abnormal cells that are not easily visible.
