Don’t Hate the Floss Boss

Everybody hates the annoying flossing lecture they get at the dentist.  The news media has capitalized on these feelings recently by running a sensationalized story questioning the value of flossing.  As a result, 300 million Americans threw their boxes of unused floss into the streets and started dancing for joy.  The story claims that there is little evidence to support flossing, and it is right… kind of.

 

There are very few well designed studies that support flossing.  The reason for this is that for over a century it has been kind of obvious that flossing removes plaque from spots that are otherwise not cleaned by brushing or the by mouth’s natural cleansing mechanisms.  Just because there are no studies that show a rake can collect leaves, it doesn’t mean that it can’t.

Here is what we do know based on the most current studies and findings:

  • The plaque mass that is removed by flossing is 70% bacteria.1
  • The bacterium releases acid and toxins that cause cavities, bad breath, and periodontal disease.2
  • Periodontal disease is essentially inflammation in the gums that causes loss of the supporting bone around the teeth, leading often to recession, infections, and loose or lost teeth.3
  • Hundreds of studies are now published every year proving that chronic inflammation, like the type represented by periodontal disease, is a risk factor for many systemic diseases including cardiovascular disease, diabetes, rheumatoid arthritis, Alzheimer’s disease, pulmonary disease, cancer, erectile dysfunction, and dozens of others.4-10
  • The link between oral inflammation and arterial disease is so strong that the nation’s leading cardiologists are now describing oral disease as one of the single most important factors leading to strokes, heart attacks, and other vascular issues.11
  • The Chief Wellness Officer at The Cleveland Clinic, one of the world’s most respected medical centers, has announced that on average flossing can add nearly six-and-a-half years to your life.12

 

Forget what you hear on the news.  Don’t believe everything you read on Google.  Ignore any dental advice you get from your friends at the gym.  Listen to your dental hygienist… If you got ’em, floss ’em.
