Post Nasal Drip
Post nasal drip can be a problem for many people – even those with good oral hygiene.

There is a test which you can do. Stick out your tongue and lick an un perfumed wrist. Wait five seconds, and take a sniff. Almost everyone's tongue has an odour.In many people with bad breath, a careful scraping of the back of the tongue with a small spoon can reveal a yellowish mucous material. The odour on this spoon is very reminiscent of the odour of the whole of the mouth.

As before, regular cleansing of the tongue with a brush or tongue scraper certainly helps. Additionally, great benefit can be obtained from the use of a mouthwash which should be swished around the mouth and gargled for a minute or so. Good products to use here are Retardex and Dentyl mouthwashes which are readily obtained from chemists and supermarkets.

Strangely, the breath may be fine during breathing, but only may become a problem during speech when the tongue is active.

Importantly- Don’t Worry!
The problem you may think you have may not have been noticed by anyone else.
Other conditions causing bad breath:
   The presence of a foreign body in the nose or sinuses
   Lung throat and sinus infections/problems
   Uncontrolled diabetes
   Liver and kidney problems.
All of which are rare and would need to be diagnosed by your medical GP.
