Halloween Advice – With a Grain of Xylitol

Today the Wall Street Journal published Halloween dental advice about preventing cavities. Dr. Ruchi Sahota, the spokeswoman for the American Dental Association, agreed “sugar-free chewing gum” combats harmful bacteria in the mouth and certain studies show xylitol adds minerals to tooth enamel. Then came the “but” ….as Dr. Sahota explains the evidence is not conclusive to show xylitol prevents cavities.

I want patients to be aware of this “cause” argument, because it is often used to muddy scientific waters. There are people who say bad teeth do not “cause” heart attacks, and gum disease does not “cause” dementia etc. They are technically correct because there is only a link. For example, gum disease bacteria produce inflammation that spreads through the body and results in higher risk for heart attack, dementia etc. As you can see, it’s politician-type talk. The words are correct but they give the wrong impression to the listener. I have a problem because it’s not truth – it’s deceptive.

The reason it’s so difficult to prove something is a “cause”of a health problems is because you’d have to create conditions that give some in the study group a heart attack etc. For teeth, we’d have to give one group of test children sugar candies to “cause” cavities and compare with the kids eating xylitol. Of course this would be unethical and scientists know it. The problem is that the public mis-interpret these statements – assuming it means “there is no connection” – which is grossly untrue.

I suggest you take what the ADA says about xylitol with a grain of salt (or xylitol) and although the ADA says “nothing takes the place of your toothbrush to keep your teeth and gums healthy” I’d like to see some causal science to prove that!

According to the Cochrane Study, the evidence from the 10 studies that they could use to answer the question of the meta analysis in this study showed that there was some evidence that the combination of xylitol and fluoride may reduce tooth decay and the remaining evidence found did not allow them to conclude whether or not any other xylitol-containing products can prevent tooth decay. So the ADA representative “interpretation” of the results as to the evidence being not conclusive is correct, but it doesn’t mean that xylitol is not effective.

Hello,
I’m sorry my english is broken, I’m French.
I found your recommendation using your system for people living outside the US.
I can buy fluorigard and retardex toothpaste on amazon.fr.
I’m a bit skeptic about the ingredients of the toothpaste. There is no fluoride and the paste contains glycerine and sodium bicarbonate. Will it be ok to use the toothpaste?
My system :
Retardex
retardex toothpaste (no fluoride)
listerine regular mint
fluorigard

and xylitol throughout the day.

thanks for your answer

    We have to do the best we can…. you may look for some Swiss toothpastes that may be available in France.
    Elmex is a good brand: LINK
