Last time I gave an example of the desperation evident in
people’s behavior to find some simple miracle to improve their health and
wellbeing. All it takes is a celebrity endorsement, some anecdotal evidence on
a TV doctor show, a news report about preliminary findings or a viral video and many people decide to adopt a new habit, product or procedure without any
research. The professionals are then
forced to react with warnings and watch-outs to protect their patients from
potential harm.
It happened again this month after a YouTube post by someone
going by the name of Mama Natural became an instant success, reaching millions of viewers. This was not about a miracle cure for your
body, but for a miracle teeth-whitening solution. Now, according to Fox News and others, dentists are
“warning against using [this] DIY whitening trend that involves smearing a
charcoal-derived black mixture on teeth” saying it “may lead to enamel
deterioration and tooth erosion.”
Activated charcoal capsules are available in health food
stores or on line. The video recommends
that you break open a capsule and mix the powder with water to achieve a pasty
texture. Then either brush it directly
onto your teeth or instead just swish the powder around in your mouth. Rinse after three to five minutes (some say
up to ten minutes) and see the results. Endorsements, testimonials and spokespersons say you will see whiter teeth almost immediately.
The theory is that activated charcoal absorbs impurities. It has been used in air filters and in
emergency rooms to treat poisonings and drug overdoses. More recently activated charcoal has been
adopted into beauty products, such as skin creams and facial masks, to
supposedly produce benficial effects by absorbing impurities on the skin. The next logical step is to use it to
deep-clean teeth, remove the stains and get them sparkling white.
Not so fast! The
responsible articles point out that not enough evidence is available to tell if
charcoal brushing is beneficial or dangerous.
The charcoal itself might be too abrasive. Over time it might actually be removing
enamel along with those stains. When you
lose enamel, not only do your teeth get sensitive, but the tooth enamel is
lost. Enamel can’t grow back as cut skin
or broken bones do. Once it’s gone, it’s
gone.
While dentists are concerned, the natural websites are
spreading the news. This one gives
instructions, promotes it as a "natural" way to whiten teeth and mentions only the messiness as a potential downside. (The pictures accompanying some of these stories are really disgusting, so messiness is indeed a problem, though a minor one.)
But dentists have only themselves to blame. Over the past 10 to 15 years I have noticed
more radio, TV, direct mail and Internet advertising for dentists with most of
them emphasizing the whiteness of your teeth over the health of your
teeth. Catch phrases like “show me your teeth,”
“perfect smiles” and similar ones stress the superficial side of oral hygiene. Most dentists offer tooth whitening as an
extra service. So why are they
surprised? How can they really blame patients when a potentially less expensive
way to get the same results comes on the market or over the Internet? When you start appealing to appearances over
the practical need to see a dentist regularly, it may work to bring in business
in the short run but you will soon find yourself in a different competition.
