Why so dry? Dry mouth and what you can do about it.
What causes dry mouth? There can be many causes but usually it's a combination of these:
- more than 400 medications have dry mouth as a side effect and the number keeps growing
- blood pressure medications and antidepressant medications are known for their dry mouth side effects
- Diabetes, HIV/AIDS and Sjogren's syndrome are known to reduce salivary flow significantly
- cancer treatment
- radiation therapy of the head and neck can damage the salivary glands reducing salivary flow to almost nothing
- chemotherapy drugs can cause saliva to become much thicker causing the mouth to feel uncomfortably dry
- nerve damage
- injury to the nerves of the head and neck can limit the signals going to the salivary glands which tell them to produce saliva
- foods containing caffeine can reduce salivary flow
- salty foods can make the mouth feel particularly dry
- tobacco use
- the smoke from cigarettes has a drying effect in the mouth
- the nicotine from tobacco reduces salivary flow
What can you do about dry mouth? Treatments are tailored to the cause of xerostomia when it can be diagnosed.
- xerostomia that's caused by a medication can sometimes be helped by changing the medication or changing the dosage. This would need to be done by the prescribing physician.
- for salivary glands that are damaged or not functioning completely there are some medications that can help stimulate salivary flow.
- there are some salivary substitutes that can be helpful.
- sleep with a humidifier
- chew sugarless gum or mints (preferably sweetened with xylitol) to help stimulate salivary flow
- sip on water throughout the day and particularly at meals
- brush and floss regularly
- don't smoke or chew tobacco (one more excellent reason not to!)
