Could it be my deviated septum is causing bad breath?

Not typical. Tonsil issues, reflux, sinusitis, poor dental and oral hygiene and some types of food you eat are much more likely to cause bad breath than deviated septum. Septal deviation typically interferes with nasal airflow and contributes to the sensation of a stuffy nose.
Yes. Nasal septum deviation is a common physical disorder of the nose, involving a displacement of the nasal septum.Symptoms of a deviated septum include infections of the sinus and sleep apnea, snoring, repetitive sneezing, facial pain, nosebleeds, difficulty with breathing, and mild to severe loss of the ability to smell and postnasal drip, all those symtoms may cause bad breath.
Unlikely. A deviated septum normally causes blockage of nasal passages not bad breath. Sometimes food and debris can get caught in your tonsils causing bad breath. You might also see your dentist to be sure you don't have gum disease.

Have a deviated nasal septum, don't want surgery. Been causing post nasal drip & bad breath for years, taking nasal spray & antihistamine. Not helping.

Reconsider . A deviated nasal septum can cause a lot of problems. My patients who have the surgery almost all wish they had it done sooner. Get in to see an ENT (maybe get a second opinion). He/she can give you more information pertinent to your case. Bad breathe and nasal drip can be a sign of sinusitis and if so, often needs antibiotics. So, a visit to a good ENT will be worthwhile.

Let's rethink this. Deviated septums don't cause post nasal drip; they cause nasal obstruction. Usually they don't cause any symptoms at all. Your post nasal drip could be caused by your nasal spray if your spray is an over-the-counter decongestant spray (oxymetazoline, xylometazoline). Try using saline spray instead of otc decongestant sprays. That may help. Your best bet: see an otolaryngologist or allergist. Read more...
