  • "Tongue Scraping vs. Tongue Brushing for Treating Halitosis (Bad Breath)"

  • Increased public awareness and demand for bad breath remedies

  • have resulted in a substantial growth of the breath freshening industry

  • and the saturation of the market with breath-improving products

  • such as mints, chewing gum, breath sprays, and pills,

  • the majority of which have only a short-term 'masking' effect

  • on bad breath and are essentially ineffective.

  • Well, what can we do? Could it be as simple as swishing with some water?

  • Take morning breath.

  • Malodorous breath upon awakening after a night's sleep

  • is a common condition known as "morning bad breath.”

  • The most common cause of bad breath in general is

  • the degradation of protein and protein fragments by

  • microorganisms residing on the tongue and teeth, particularly

  • the sulfur-containing amino acids cysteine and methionine

  • that are broken down into volatile sulfur compounds

  • like the rotten eggs gas hydrogen sulde.

  • Approximately 50 per cent of the adult population

  • has early morning concentrations of these compounds in mouth air

  • thatexceed the threshold of objectionability

  • established by theorganoleptic panel.”

  • What does that mean?

  • The organoleptic method is considered the gold standard

  • in the examination of breath malodor.

  • Basically, all this means is some examiner sniffs the air

  • exhaled from the mouth and nose and subjectively defines

  • the presence or absence of odor.

  • And when people's morning breaths are sniffed

  • about half exceed the threshold of objectionability.

  • Why? What causes it? A dry mouth.

  • Low salivaryow, particularly during the night,

  • creates like a stagnant pond effect,

  • favorable for bacterial proliferation and putrefaction,

  • and so to reduce morning bad breath,

  • you may read suggestions that rinsing with or drinking water

  • upon awakening is effective, but you don't know...

  • until you put it to the test.

  • The effect of water on morning bad breath:

  • a randomized clinical trial.

  • One group was randomized to rinse their mouths

  • with a tablespoon of water, and the other to drink about a cup.

  • And... they both worked, significantly improving bad breath,

  • with no apparent difference between them,

  • though they didn't have a control group,

  • and it would have been interesting to see how much their breath improved

  • just being awake with their normal salivary flow.

  • After drinking and eating in the morning,

  • morning breath tends to disappear.

  • People brush their teeth in the morning thinking that's going to help,

  • but that may only reduce rotten egg gas levels 30 percent,

  • whereas eating breakfast works twice as well,

  • a 60% drop in hydrogen sulfide levels.

  • The mechanical action of chewing stimulates the flow of saliva

  • and the passage of food over the surface of the tongue

  • removes the putrefied surface film,

  • thus simulating the action of tongue brushing.

  • Well, if it's a matter of the amount of tongue coating there is,

  • how about actively brushing your tongue, like you would your teeth,

  • and you get closer to a 70% drop, suggesting the tongue

  • is the major source of the stinky gasses.

  • Other studies, though, show no benefit to tongue brushing

  • on oral odor in both adults and children.

  • The researchers suggest maybe the gag reflex

  • kept people from doing a better job?

  • What about tongue scraping?

  • In this study they compared tooth brushing, brushing plus flossing,

  • brushing plus scraping, or all three, and they found that

  • adding flossing didn't really seem to affect morning breath,

  • and that tongue scraping won the day against tooth brushing,

  • suggesting that tongue cleaning may be the most important

  • hygienic procedure to reduce morning bad breath.

  • This is not to suggest toothbrushing doesn't help with bad breath.

  • Here, they had people stop brushing their teeth for 5 days

  • but continue to floss and tongue scrape,

  • all while doing their fancy organoleptic technique

  • where they blew through a straw in some poor examiner's nose,

  • and despite all that scraping and flossing,

  • their breath got worse when they stopped brushing.

  • What about tongue brushing versus tongue scraping?

  • Researchers compiled all the randomized controlled trials

  • comparing different methods of tongue cleaning to reduce mouth odor

  • in adults with halitosis and

  • the tongue scraping was found to be

  • slightly more effective than tongue brushing.

  • Perhaps the fact that the width of a toothbrush is smaller

  • than the width of a regular tongue scraper might make it

  • less effective in removing loosened debris from the tongue.
