There is also a device called a ViziLite that helps dentists detect oral cancer early, before white patches are visible. A ViziLite exam may be covered by insurance.
Early detection and treatment can give the patient an 80% or better chance at survival. That's the kind of number we like to see. You can do a self-examination for oral cancer. However, to get access to the latest technology and to have the best chance at early detection of oral cancer, see a dentist regularly as well.
