How to deal with dry mouth when you are using a CPAP machine

The most common side effect of using a CPAP machine is dry mouth. Some people would experience a dry mouth almost immediately after the first use of a CPAP machine. A dry mouth can lead to further health problems such as bad breath, bleeding gums and nosebleeds. The result is often more difficulty falling asleep, leading to other breathing problems and worse comfort problems. In this article, we will share with you simple solutions to manage this common CPAP machine symptom and explain how to fix it with simple actions.

Dry mouth occurs when the glands produce insufficient saliva. It is not considered a serious disease, but it is sometimes a symptom of another disease. A dry mouth can be very uncomfortable and annoying, but you don't need a doctor to fix it. Here are the tips to help you.

Drink More Water

Drinking water and staying hydrated can help relieve dry mouth. We have found that dehydration may be a factor in dry mouth. Increasing your water intake can help treat mild dehydration.

Your CPAP mask may not be right for you

One of the most immediate solutions to dry mouth is to check your mask choices. There are many mask options to suit different sleep and airflow patterns. However, if your mask is not being fitted correctly, or is not the right size for you, consider a custom mask that will solve your dry mouth and fit comfortably on your face

In some cases, the problem is from a broken mask, leaking air, and causing a dry mouth. As we just mentioned, the leak could be due to an ill-fitting mask, but it could also be due to a broken strap or a broken device. Regular care and maintain your machine will help you deal with these issues, as well as frequent and thorough cleaning of your mask.

Change bad habits


  • Avoid caffeine. Caffeinated beverages can make you dehydrated. Drinking caffeinated coffee or tea can cause dry mouth.
  • Limit alcohol consumption. Alcohol can be dehydrating, which can lead to dry mouth.
  • Stop smoking. Smoking can also cause dehydration. Reducing or quitting smoking may reduce symptoms of dry mouth.
  • Less sugar. Sugar can take lots of water from you. If you can, try to cut back on sugary foods to reduce dry mouth problems.

Try an air humidifier

This is actually a quick and easy way. For the perfect sleeping environment, you can use an air humidifier. By adding moisture to the air with a humidifier, dry mouth symptoms are quickly relieved, and most users find this to be an effective solution to the problem. Some CPAP machines come with a built-in humidifier, saving you the cost of purchasing a separate humidifier for your bedroom. 

If you have had this problem for a long time and have other symptoms. Please consult your doctor as soon as possible.
