Suffering from post-nasal drip can be a real drag, particularly if you have seasonal allergies. Not only can sinus drainage lead to coughing and sore throat, but it may also result in powerful bad breath. This is a problem that TheraBreath offers numerous specialty solutions for.
You may have had nasal discharge for years without knowing it. Do you regularly get halitosis? Do you find yourself with the persistent need to swallow, cough or blow your nose? Do you get colds easily or suffer from allergies? If the answer to any of these questions is yes, post-nasal drip may be to blame.
The National Institutes of Health states that all of the above conditions can lead to nasal discharge, as well as flu, sinus infections and bacterial infections. That latter problem – an infection caused by microbes – is the key to explaining how nasal drip can cause bad breath.
You see, as nasal mucus slides down the back of your throat, it deposits microorganisms on the root of your tongue and on your tonsils. This thick goo creates a biofilm, meaning a living layer of bacteria, in your oral cavity.
