Dry mouth, a conditional also known as xerostomia, is reported to affect a third of the US adult population. There are two main causes for xerostomia. The first is aging. Saliva production naturally decreases as we grow older. The second most common cause is medication. More than 600 different types of medication site dry mouth as a common side effective. Medication for everything from allergy to blood pressure can lead to xerostomia. While not as popular as aging and medication, there are other possible causes of dry mouth including dehydration, chemotherapy, Sjögrens Syndrome, Parkinson’s Disease, diabetes and a variety of autoimmune diseases.An adult should produce between four and six cups of salvia daily. If your mouth produces significantly fewer than four cups of saliva, a number of unpleasant side effects may arise. Some of these symptoms include:

  • Mild to severe mild dryness
  • A burning sensation on the tongue and/or oral tissues
  • Chronic halitosis / bad breath
  • Gum disease
  • Increased tooth decay
  • Difficultly eating drier foods
  • A change in taste or speech
  • Cracks at the corners of the mouth
  • Difficulty swallowing

If you are suffering from xeostamia, there are a number of strategies you can employ to alleviate symptoms, including:

  • Stay hydrated, drink 8 or more glasses of water each day
  • Avoid excessive alcohol, including alcohol based mouth rinses
  • Avoid tobacco, caffeine, carbonated beverages and spicy food
  • Use products for dry mouth such as saliva producing lozenges and sprays

If you suspect your dry mouth is the result of a medication you are taking, talk to your doctor about possible alternatives. If symptoms persist, speak with you doctor about other possible causes. You may need to be tested for autoimmune diseases that may be attacking your moisture-producing glands.About the Author: Dr. Anthony Dailley has been practicing dentistry since 1981 and specializes in curing bad breath solutions.

Dry mouth is very common to people who always eat salty food. It's also a good attitude to always drink water at least a liter a day.

I agree with the previous comments. There are several factors that cause dry mouth. They can be dehydration or they can be an implication of an impending internal defects or disease. Eating too much of a salty food can indeed increase the possibilities of getting dry mouth thus, also increases water intake. It's good to consult your doctor and dentist about this problem as this may cause severe and untreatable diseases.

Xerostomia can be a secondary symptom of an ongoing health condition. Dry mouth can cause bad breath and may cause additional infections since the natural environment of the mouth is being affected. Mouth is wet in nature and it must maintain its wetness all throughout. It's good to always drink plenty of water everyday to ensure hydration of the entire body system.

I always experience Xerostomia every time I wake up. I have been drinking water a lot but the dryness won't go away. I think I really need to consult my doctor about it.

I have been suffering from Xerostomia and my dentist suggested that I should be taking at least 8 glasses of water a day. Avoiding caffeine and cigarette can help as well.

Dry mouth is definitely annoying. What I do to prevent it from happening is brush my teeth regularly and use mouth wash right after. Going to the dentist in Summerville also helps.

If there's one thing I hate, that would be having dry mouth. I had to go the Rockford dental care three times last week just to have it treated. They said it had something to do with my tonsils.
