Oral cancer screening is an examination performed by a dentist or doctor to look for signs of cancer or precancerous conditions in your mouth.

The goal of oral cancer screening is to identify mouth cancer early, when there is a greater chance for a cure.

Most dentists perform an examination of your mouth during a routine dental visit to screen for oral cancer. Some dentists may use additional tests to aid in identifying areas of abnormal cells in your mouth.

People with a high risk of oral cancer may be more likely to benefit from oral cancer screening, though studies haven’t clearly proved that. Factors that can increase the risk of oral cancer include:

• Tobacco use of any kind, including cigarettes, cigars, pipes, chewing tobacco and snuff, among others
• Heavy alcohol use
• Previous oral cancer diagnosis
• History of significant sun exposure, which increases the risk of lip cancer

During an oral cancer screening exam, your dentist looks over the inside of your mouth to check for red or white patches or mouth sores. Using gloved hands, your dentist also feels the tissues in your mouth to check for lumps or other abnormalities.
