How Your Dental Screening Can Prevent or Detect Cancer

You may think that your routine dental visits are just to get your teeth cleaned. That is partly true. The real benefit to your routine dental visits is that it can serve as an oral screening exam.  Dentists and dental hygienists examine your mouth, tongue and surrounding tissues much more closely than you do and are most often the people who find pre-cancerous or cancerous lesions in early stages of growth.

Did you know almost 42,000 Americans will be diagnosed with oral and throat cancers this year? And that the 5-year survival rate of those diagnosed is only slightly more than 64 percent? When cancer is detected and treated early, treatment-related health problems are reduced. A thorough screening exam includes more than looking around your mouth. Your dentist will examine and feel your face, neck, lips, mouth, tongue, thyroid gland, salivary glands and lymph nodes for any abnormalities. If you have dentures or partials, they should be taken out to allow the entire mouth to be inspected.

People who smoke, use smokeless tobacco and drink alcohol are at higher risk of developing oral cancers. However, in recent years, oral cancers in younger people without these risk factors are on the rise. This is due to the prevalence of human papillomavirus (HPV), a sexually transmitted virus that is known to cause cancers of the oral cavity, cervix, anus, penis, vagina and vulva. In addition, other cases occur in people with no risk factors at all, so screening is important for everyone.

Some dentists offer additional testing to detect pre-cancerous or cancerous lesions such as special lights. The Journal of the American Dental Association published a review of these techniques, which found that there is insufficient evidence to support or refute the use of visually based adjunctive techniques. The study noted the importance of a thorough oral exam as the best method to detect oral lesions.

In addition to routine dental screening, you should be aware of the potential signs of oral cancers and report these to your healthcare provider. Remember that many of these can be caused by non-cancerous (benign) conditions, but still warrant a trip to your healthcare provider for further investigation.

Signs to report:

  • A sore that bleeds easily or does not heal
  • A color change of the oral tissues
  • A lump, thickening, rough spot, crust or small eroded area
  • Pain, tenderness, or numbness anywhere in the mouth or on the lips
  • Difficulty chewing, swallowing, speaking or moving the jaw or tongue

So, your routine dental cleanings may in fact save your life!
