What Causes Dry Mouth?
Dry mouth can have many potential causes. Here are some of the most common causes of dry mouth:
- Sleep apnea
- Salivary gland cancer
- Sjögren’s syndrome
- HIV / AIDS
- Parkinson’s disease
Dehydration is the most common cause of dry mouth. Make sure you’re drinking enough water and not consuming too much alcohol. Remember to increase your water consumption when you exercise or spend time in hot weather.
Diabetes can diminish salivary production and change the composition of your saliva, making it less effective at wetting your mouth and protecting your teeth.
Sleep apnea leads to dry mouth because people often breathe through their mouth to try to restore and maintain air flow. This evaporates saliva, and people wake up with a dry mouth.
Medications are a common cause of dry mouth. There are literally hundreds of medications in use today that cause dry mouth as a side effect. If you don’t suspect any of the above causes, talk to your doctor about this side effect.
The other causes are less common, but if you can’t explain your dry mouth, talk to your doctor about these.
