Therefore, those people who suffer from post nasal drip, sinus problems, and other such ailments are more prone to bad breath and lousy tastes in their mouth. The anaerobic bacteria uses the post nasal drip mucus as a food source and starts to extract sulfur compounds from the amino acids that make up the proteins found in all this excess mucus.

Scientifically, the anaerobic bacteria that cause bad breath “love” the amino acids Cysteine and Methionine. These amino acids are the building blocks of the proteins that are found in post nasal drip, and can even be found in dairy foods. In fact, most people notice that when they drink too much milk or eat too much cheese, they end up with more mucous or phlegm in their throat. This is a natural reaction for many people and unfortunately, ends up causing more bad breath and a lousy taste in your mouth.

If you still have your tonsils, you may be harboring a higher number of the bacteria which can lead to an “interesting” and very often misunderstood phenomenon, called TONSILOLITHS. Literally translated, they are “tonsil stones” produced by the conglomeration of post nasal drip mucus draining down the back of the throat, and the volatile sulfur compounds created by the bacteria. These bacteria easily end up in the “nooks and crannies” of the tonsils every time one swallows. I can’t tell you how many stories I’ve heard from my patients who asked their dentist what these objects were, and more often than not the answer was ‘food particles’. This couldn’t be further from the truth!


There are essentially only a few different routes that you can take:

1. Use medication and or drugs to dry up the sinuses and prevent post nasal drip mucus buildup – all the while being careful to avoid a dry mouth, a likely side-effect of virtually all antihistamines. Dry mouth is the most common initiator of bad breath because it mimics an anaerobic environment, perfect for the “bugs” to pump out volatile sulfur compounds. You should be careful about using any antihistamine too frequently – many are habit forming!

2. Use TheraBreath Nasal Sinus Formula. I recommend squeezing 3-4 drops into each nostril and then lightly inhaling to move the potent formula through the sinuses twice daily. Most people can finally experience that fresh breath and taste feeling after the formula effectively eliminates the production of sulfur compounds created by the reaction of post nasal drip and the anaerobic sulfur producing bacteria.
