Neti pots may not improve post-nasal drip, bad breath
In winter, bad breath caused by post-nasal drip can go from moderate to extreme. Seasonal colds, flus and sinus infections may cause an increase in nasal mucus and add a tinge of halitosis to every breath you take. The neti pot, a common sinus-clearing tool, may ease the drip but is not likely to improve your bad breath.
As reported by the Ottowa Citizen, neti pots are small, teapot-shaped ceramic vessels used to pour salt water through the nasal passages. The Mayo Clinic has said that neti pots may relieve symptoms of sinusitis and nasal allergies, and medical studies have shown that saline irrigation of your nose has few if any side effects.
However, removing the cause may not remove the symptom. Bad breath caused by post-nasal drip originates in the back of the throat and can migrate to the tongue and palate. Post-nasal leakage often contains bacteria that emit smelly sulfuric compounds as they grow and multiply. While irrigating your nose might cleanse it of bacteria, the saline from a neti pot comes nowhere near the throat or mouth, leaving bacteria to flourish and create foul breath.
To knock out cold- and flu-related halitosis, consider rinsing your mouth with a specialty breath freshening product, particularly those that moisten the mouth and counteract the compounds associated with bad breath.
