There is a wealth of research showing a strong link between your coated tongue -yep, I mean that furry stuff growing on it - and bad breath (or oral malodour as the boffins like to call it).
And probiotics have an answer for it!
A 2007 study concluded that people with bad breath have different bacteria on their tongue than people that don't. This indicates that a coated tongue and the halitosis that goes with it are caused by bacteria.¹
There are a number of different bacteria that produce the unpleasant smell of bad breath but it is the hydrogen sulphide-producing bacteria that are the main culprits. You'll find that Blis K12 and M18 probiotics can effectively fight this type of bad breath that is caused through a coated tongue.
Everyone has these hydrogen sulphide-producing bacteria in their mouth, but it is when they invite too many of their relatives along that trouble starts. It is the INCREASE in the number of H2S-producing bacteria in the biofilm that coats the tongue that is responsible rather than the fact that they are there.²
That biofilm is your furry tongue!
Interestingly, at a 2007 Dental Conference there was a paper presented (called "Cognition of own tongue coating by patients complaining of oral malodor") showing that more than half the people in the group studied had no awareness of their own tongue coating. The rest of us, of course, worry endlessly!
The dorsal area is simply the back part of the tongue and unfortunately it is prime real estate for bacteria. It's drier than many parts of the mouth and doesn't get cleaned so often or so thoroughly, in short just the sort of place that bacteria enjoy.
So, a few of the wrong sort of bug set up home, feed on the remnants of food, dead skin cells and postnasal drip that they find, breed profusely and you end up with a coated tongue and breath that could stop a charging rhino. How fair is that!
Seen under the microscope, the tongue's surface is one of hills and valleys and within that convoluted terrain the anaerobic bacteria flourish, breaking down the protein "bits" they find into foul smelling gases. Your volatile sulfur compounds, no less.
The Multi-Symptom ProBiotic Breath Treatment Kit complete with tongue scraper deals to both the coated tongue and the bad breath at the same time. This has to be the most effective probiotic kit around.
The volatile sulphur compounds produced by the bacteria are "significantly increased in patients with periodontal disease."³ It seems fairly straight forward to me, that if you have infections in your mouth, or holes around the gum line where bacteria can get in and party, you're going to have bad breath. So first port of call would be your dentist and get the teeth seen to.
You'll find this special strain of probiotic in Now Foods Oralbiotic Blis K12 and Oral Probiotic Formula Strawberry Flavor 30 Chwbls They both contain the same probiotic, both excellent and both work.
And if you're in the UK your local Amazon sell them Oralbiotic Blis K12, 60-Count.
If you don't recolonize the mouth, then whatever it is that caused the bad breath bugs to create that coating on the tongue in the first place, will allow them to rapidly increase their population again.
When you recolonize the mouth with good bacteria, then the baddies have to fight for elbow room.
After recolonizing, the good bacteria might hold their own, or according to this 2007 report4 you might need to repeat the recolonizing process every now and then. I use the K12 strain twice a year - spring and autumn.
Either way, your coated tongue is gone. It's a sweet deal for sweet breath.
