CPAP mask and Halitosis

by Dave
(Naples Fl.)

I have a Respironics cpap unit with a strap that goes over the head and two nasal pillows which put the airflow into my nose.

I get serious dry mouth each morning. My question is, "can the nightly dry mouth create halitosis during the night?"

My wife says that my breathing is foul and I wonder if this is the cause. Could a chin strap help? I don't think I have a breathing issue but I do have a deviated septum.

Your advice is very appreciated.


You may be right: dry mouth can cause bad breath or halitosis.

As you probably know, the saliva helps you to neutralize the acids produced by bacteria localized on your tongue and it also helps you to prevent tooth decay.

With dry mouth from CPAP, you almost have no chance to escape from bad breath (halitosis), even if you wash your teeth 10 times a day.

However, you have to consider the risk factors for halitosis, such as:

  • improper digestion,

  • acid reflux,

  • medications,

  • drainage from your sinuses,

  • poor oral hygiene,

  • Gingivitis,

  • Periodontitis,

  • canker sores,

  • and many other.

There is a very detailed article about how to stop dry mouth problem when you use a CPAP machine. All the tips included in this article are based on the experience of thousands of CPAP users with dry mouth.

I hope it helps. Don't be afraid to comment back.
