Oral Cancer Screening in Toronto

An oral cancer screening is a clinical exam performed by a dentist or healthcare provider to look for early signs of cancer or precancerous lesions in the mouth. Early detection through screening increases the chances of successful treatment and helps catch abnormalities before they progress.

During the screening, your dentist visually inspects and feels the tissues inside your mouth — lips, tongue, cheeks, gums, throat, and neck — for red or white patches, sores, lumps, or other unusual changes. Some clinics may use special lights or dyes to highlight abnormal areas.

Oral cancer screening is typically part of your regular dental checkups. Most providers recommend at least once per year, and more frequently if you have risk factors such as tobacco use, heavy alcohol consumption, prior oral cancer, or persistent symptoms.

Seek evaluation promptly if you notice any sore or ulcer that doesn’t heal within two weeks, persistent red or white patches, unexplained lumps or thickened areas, bleeding without cause, or persistent pain, numbness or difficulty swallowing.

No special preparation is needed, and the screening exam itself is painless. It is usually done in a few minutes during your routine dental visit. If abnormalities are found, your dentist may recommend further tests, such as a biopsy.
