Oral cancer: Is new screening technique helpful?

Dentists typically check for signs of oral cancer, such as white or red patches in the mouth or persistent mouth sores, during routine dental checkups. Some dentists also recommend an additional oral cancer screening called a ViziLite exam. You rinse your mouth with a cleansing solution, and then your dentist or hygienist examines your mouth with a light designed to highlight abnormal tissue. Although the exam may be appropriate for people who have a high risk of oral cancer, it hasn't been proved an effective way to decrease the risk of death from oral cancer and may not be covered by dental insurance. The best way to reduce your risk of oral cancer is to avoid tobacco and heavy alcohol use. Make sure your dentist inspects your mouth for signs of oral cancer during routine exams. If you're interested in more specific testing, ask your dentist for details.
