I recently came across an Internet blurb by Dr. Harold
Katz, a dentist who heads the California Breath Clinics and
author of the Bad Breath Bible. Having been in the dive business
forever, I've never encountered a diver with the pariah's
affliction called "Diver's Mouth," but perhaps the dive boats'
exhaust fumes have prevented me from noticing.
Katz writes: "Some people who take up scuba diving find
that, after a few weeks, they suffer from jaw aches and halitosis.
What is going on here? Can anything be done about
it, short of finding a new hobby? The good news is that no
one needs to quit scuba diving just because it gives them bad
breath. In fact, there is a name for this condition - - 'diver's
mouth syndrome.'
"Several studies appearing in the journal Dental Update have addressed diver's mouth. Novice divers choose a mouthpiece
that is too small for their teeth and jaws, researchers
say. As new divers swim underwater, they clench their teeth
into the rubber of the mouthpiece, both out of excitement
and because they're towing an oxygen (sic) regulator with
their mouths. Biting into a poorly-fitted mouthpiece can
cause jaw aches, and lead to nicks in the gums. These small
cuts may get infected, leading to oral odor and gum pain.
"Besides choosing a better-fitting mouthpiece, individuals
with diver's mouth may consider using a specialty breathfreshening
rinse that contains no alcohol or sodium lauryl
sulfate. Such products kill bacteria without further irritating
the gums."
So, whenever you open your mouth on a dive boat, and
your fellow divers jump overboard, you, my friend, may have
the dreaded Diver's Mouth. Beware.
