Hello there,
In the vast majority of cases a furry tongue, or coated tongue, is just something that happens naturally (for most adults anyway!). After eating for instance, a coating builds up on and underneath the surface of our tongues, because food gets trapped in between our filliform papillae (the tiny cone-shaped structures which give our tongues its "velvety" appearance).
Cleaning your gongue regularly after each main meal, as part of your oral hygiene routine, is the best way to get rid of any coating that has built up in the past few hours. Doing it before going to bed will also help minimise morning breath.
For those who suffer from chronic halitosis, tongue cleaning is basic. Although on its own will not cure halitosis, it will certainly minimise its offensiveness.
Post nasal drip (mucous dripping down the back of the throat and ending un on the tongue too) is another cause of bad breath, causing a coating to build-up on the tongue surface quite quickly. Other causes of furry tongue are less likely, such as Candida Albicans (a fungal infection).
Having an overall bacterial imbalance in the mouth – for whatever reason – can also cause this white coat to build up at a higher rate.
But in all these cases, the best way to get rid of this white coating is to remove it mechanically with a tongue brush /scraper. I have tried a handful of them, and I find the Ora Brush to be by far the most effective and easiest to use. It is also quite cheap and last for a long time, which is a bonus…
I hope this helps! :-)
