“Once in a while, I come across a news story that catches my professional eye. On a lazy Sunday morning I was treated to a news story that got my full attention because it contained some rather shocking headlines.
“This particular story had everything needed to raise my already high blood pressure to even greater levels than the deadly mouthwash I had foolishly inflicted upon myself an hour earlier!
“So with a deep concern for my own imminent death and the mortal danger my wife also subjects herself to on a daily basis, I considered pouring these toxic products down the sink immediately. But, as a rational scientist and oral microbiologist I first took it upon myself to read the research paper this news report was supposed to be based upon (Free Radical Biology and Medicine, 2013, 55: 93-100).
“The paper showed that using Corsodyl mouthwash containing 0.2% chlorhexidine reduced physiological levels of nitrite whilst increasing nitrate. In the circulatory system, nitrite causes vasodilation (expansion) of the blood vessels, which in turn causes a lowering of blood pressure.
“Although the core findings of the paper appear credible, the extrapolation that a reduction in the number of bacteria present in the oral cavity was directly responsible for a rise in blood pressure is perhaps less clear.
“Nevertheless, the news story conflagrates this to ‘mouthwashes can raise risk of heart attack and strokes’ and claims that they are ‘dangerous’. Such one-sided reporting on health issues makes me angry.
“What the news report fails to mention are the well-established links between excess dental plaque and tooth decay, periodontal disease and even systemic conditions including cardiovascular disease and preterm birth. The authors of the paper, quite rightly, saw fit to state this in their introduction – but the news story ignored this counterpoint since it would make their headlines less dramatic.
“I hope this particular newspaper doesn’t get hold of another little known fact; brushing your teeth, or even eating a hard apple, can force oral bacteria into your bloodstream. But this does NOT mean that brushing your teeth or eating apples is bad for you by any stretch of the imagination.
“The well-established health benefits of maintaining good oral hygiene, or consuming apples, far outweigh the often tenuously linked and minimal impact, negatives effects they might also entrain.
“Perhaps the best advice for reducing your blood pressure would be to avoid believing everything you read – especially in the tabloids.”
Was it the “Daily Fail” by any chance.
I am an e-cigarette user (a Vaper) and I am fed up to what is left of my teeth (A smoker for 35 years) with the nonsense that so-called newspapers spew out about what could possibly be damaging my health.
I have been vaping (smoke-free) for a year now and have never felt better, or, according to my GP, been better.
I wish a scientist from this University would look at and report upon the rubbish I have read in the last year.
BTW nice article!
