The AP recently released an article making the claim that “there’s little proof that flossing works”. Their review cited a series of studies that found flossing does little or nothing to improve oral health.

Here’s the problem: the studies were flawed

The AP concluded that floss does little for oral health, but it’s important to note that the evidence they cited was very weak at best. In fact, they said so themselves.

As acknowledged by the AP, many of these studies were extremely short. “Some lasted only two weeks, far too brief for a cavity or dental disease to develop” (Associated Press). They also say that “One tested 25 people after only a single use of floss” (Associated Press).

Of course the evidence is unreliable. You don’t simply develop gum disease because you forgot to floss yesterday. Cavities and gum disease do not happen overnight. You can prevent gum disease by maintaining a clean mouth over a long period of time. Wayne Aldredge, President of the American Academy of Periodontology explained: “gum disease is a very slow disease”. In his interview with the AP he recommended long-term studies which he believes would clearly show the difference between people who floss and people who don’t.

Lets put it this way: If a study claims drinking milk does nothing for bone health, but draws conclusions after only three glasses of milk, is it a reliable study? What do you think?

The fact of the matter is floss removes gunk from teeth. You can see it. Gunk feeds bacteria which leads to plaque, cavities, poor gum health, and eventually gum disease. Floss has the ability to reach the food particles that your brush can’t get to.

Aldredge also pointed out that most people floss incorrectly, using a sawing motion instead of moving up and around the teeth to clean the cracks. Positive results come from correct use and it’s critical that people learn to use a tool properly before discarding it as useless.

That’s just what floss is: a tool. Just like your toothbrush, it is designed to keep your mouth clean, and therefore keep your body safe from infection. Both your toothbrush and floss are designed to do what the other can’t, and both successfully remove bacteria from your mouth. Just like proper brushing technique, it is important that you know how to use floss properly, so that you can reap the long-term health benefits of good oral hygiene.

It’s a shame that studies on an important tool such as floss have yielded poor results, but it’s a bigger shame that the studies themselves were poorly designed. Oral hygiene is a long term process, and requires long term observations to make worthwhile conclusions. In the mean time, it’s obvious that you should continue to do everything you can to protect your well being, and floss is one of many tools that can help you do that.
