4 Ways to Help Reduce Dry Mouth When You Use a CPAP Machine

CPAP machines are commonly used by people who have sleep apnea or other diagnoses involving their oropharynx. Sometimes using a CPAP can contribute to mouth-breathing, which usually dries out your mouth. Dry mouth can wake you up coughing or with a sore throat. It can also contribute to dental problems. Treatment for CPAP dry mouth can be quite simple with possible remedies that include:

1. Check for Air Leaks in Your Mask

You might notice your mask loosening over time which can cause air leaks and reduce the efficacy of your oxygen flow. This can also cause you to breathe out of your mouth making it dry. If you are unable to adjust your mask so that it fits just right, changing to a full-face mask might be in order.

There are several styles of CPAP masks to fit your whole face and some that don't, including some that do not require a prescription

If you currently use nasal pillows, this could be part of the reason you are mouth-breathing since your jaw is not held in place. Alternating types of masks now and then could work for you until you find that special one that fits like a glove without leaking air and improves your breathing without drying out your mouth.

2. Drink Plenty of Water

Drinking water and staying hydrated is important but especially when you have medical issues that are contributing to your dry mouth. The prospect of drinking six to eight glasses of water each day can seem daunting, but it is not so bad if you break it down. Try drinking an 8 oz. glass of water every hour for six to eight hours from the time you wake up.

It's much easier to drink eight ounces periodically throughout the day than to wait until nighttime to get it all in. (Saving it up until too close to bedtime might have you getting up all night long to visit the bathroom.)

3. Use a Chin Strap

Even though your mask fits as it should, you might find a little more security if you also use a chin strap. This is especially true if you don't want to use a full-face mask.

Nasal pillows don't usually fit as tight as a more conventional mask, so adding a chin strap to your nasal pillows CPAP routine could help reduce dry mouth so that you can sleep more comfortably.

4. Humidify Your Room

Humidifiers are often used to help clear the congestion of a cold or allergies. The same heated humidifier can help reduce congestion in your chest and help keep your mouth moist. Mouth-breathing and dry mouth are common problems for people who use CPAP machines. Treatment for CPAP dry mouth is possible.
