Post-Nasal Drip Dry Mouth

By - Bad Breath Expert

When people suffer from post-nasal drip, dry mouth and severe bad breath are just a few of the symptoms affecting the ear, nose and oral/throat system. The Eustachian tube, nasal passages and various nerves intimately intertwine these systems so much that when a bacteria or virus infects one area, the others often experience symptoms as well.

"In the case of post-nasal drip, the excess mucus leaking into the back of the throat will also exacerbate halitosis because it contributes to mouth debris on which anaerobic bacteria thrive."

Anaerobic bacteria are responsible for bad breath because they produce sulfurous compounds that smell like rotten eggs. These compounds are called volatile sulfur compounds, or VSCs, and are excreted after bacteria consume and digest oral debris like food particles and mucus. When you have allergies, sinusitis or a cold that develops into post-nasal drip, the excess mucus generated by inflamed sinus tissues is abnormally thick, usually causing congestion in addition to seeping into the back of your throat.

  1. Congested sinuses swell in response to viruses or bacteria that invade healthy tissue and produce an inflammatory response from these tissues.
  2. When airways are constricted, people resort to breathing through their mouth unless they take decongestants or use nasal sprays.
  3. Mouth breathing leads to a dry mouth condition that facilitates anaerobic bacterial proliferation due to an extreme lack of saliva flow in the mouth.

In addition, the nagging cough caused by post-nasal drip expels more mucus into the upper throat and mouth. When anaerobic bacteria are provided with a constantly dry, protein-rich, stagnant environment where a deficiency of saliva cannot produce any oxygenating molecules, these bacteria will reproduce abundantly, creating vast amounts of VSCs and a serious case of chronic halitosis.


Symptoms indicating a post-nasal drip condition are:


  • A tickle in the throat that causes frequent coughing
  • Feeling like a lump is lying in the throat
  • A runny nose and/or congestion
  • Hoarseness
  • Sore throat
  • Tonsil stone formation (if the patient still has his or her tonsils)
  • Nausea and fatigue
  • Extremely bad breath

How to Treat Post-Nasal Drip, Dry Mouth and Bad Breath


For post-nasal drip caused by bacterial infections, doctors will usually prescribe antibiotics. However, colds are viral in nature and do not respond to antibiotics. While decongestant and antihistamines can reduce nasal passage swelling due to allergies or sinusitis so patients can breathe through their mouths, the ingredients included in cold medications tend to dry up the oral and nasal tissues, resulting in easier breathing but a persistent dry mouth condition.

Moreover, these over the counter medications do nothing to prevent anaerobic bacteria from thriving in a mouth that remains dry and lacking in the bacteria-killing oxygen that is provided by sufficient amounts of saliva.

While people suffering from post-nasal drip can partially treat this condition with antibiotics or decongestants, they will need to maintain excellent oral hygiene practices as well as keep the mouth as hydrated as possible in order to alleviate bad breath. This means brushing twice a day, flossing and gargling with non-alcoholic mouthwash made with natural oxygenating ingredients.

Unfortunately, what many consumers do not realize is that most mouthwashes contain alcohol and other abrasive ingredients that contribute to dry mouth and degradation of oral tissues. Popular, brand name toothpastes also contain additives like sodium lauryl sulfate, a foaming agent found in many cleaning and detergent products. SLS contributes nothing to oral health and is only used to create a "foaming" action that makes the product appear to be "working". In addition, SLS has been implicated in promoting the development of canker sores and various mouth lesions in many research studies investigating its affect on oral tissues.


Find Effective Relief for Bad Breath and Dry Mouth with TheraBreath Products


lozenges for dry mouthConsidered by doctors and dentists to be the best oxygenating oral care products available, TheraBreath offers a variety of products that can eliminate bad breath caused by dry mouth and post-nasal drip. Bacteriologist and dentist Dr. Harold Katz created his line of TheraBreath mouthwashes, drops, sprays, toothpastes, gums and mints when he realized just how much anaerobic bacteria contributed to bad breath.

Because of his extensive research concerning the association between dry mouth and halitosis, Dr. Katz manufactured several items to relieve post-nasal drip and the embarrassingly severe bad breath that it generates. These items are:

  • TheraBreath PLUS Nasal-Sinus Drops--a sinus-cleansing formula that effectively eliminates VSC-producing bacteria often concealed in hard to reach sinus passages
  • AktivOxigen Serum--mix into a solution that cleans away mucus lying at the back of the throat and is safe enough to swallow
  • TheraBreath Fresh Breath Extinguisher Spray--with a patented 6.9 centimeter nozzle capable of reaching the farthest anterior areas of the throat, where post nasal drip tends to accumulate

TheraBreath's line of oral hygiene products also includes oxygenating toothpastes that stimulate saliva flow and produce a hydrated, oxygen-rich oral environment in which anaerobic bacteria cannot survive. Bolstered by stabilized chlorine dioxide, or OXYD-8, TheraBreath's breath-freshening products introduce a powerful oxidizing agent into the mouth that rapidly destroys anaerobic bacteria along with the volatile sulfur compounds they exude. Bad breath caused by post-nasal drip and dry mouth is no match for the superior, bacteria-killing compounds that constitute all TheraBreath products.
