Suffering from dry mouth from your CPAP therapy? Finding the cause of your dry mouth takes a little bit of investigation but is easy to fix. The humidity level of your humidifier or heated tube ( if you use one) could be the culprit, there may be a mask leak or a new mask style may be needed. Patients are always welcome to call either SleepFX location and we can help troubleshoot the issue. Leduc (780) 986-5055 St.Albert (780) 459-9239
