Xerostomia is a condition where the mouth becomes very dry. This can be rather unpleasant for some people, and make people more susceptible to dental problems such as tooth decay and problems wearing dentures.

There are lots of different reasons why people get dry mouth, and there are things that you can do both to ease the condition and help prevent problems with your teeth.

It can lead to dryness, a burning or sore feeling in the mouth or a bad taste, dentures becoming loose and causing sore areas, difficulty swallowing and speaking, and more chance of getting tooth decay.

Some prescription drugs and medicines can cause dry mouth as a side effect, especially treatments for depression and high blood pressure. Also, certain medical conditions affect the salivary glands, so they don't produce as much saliva and the mouth tends to be more dry.

Making sure you don't get dehydrated by drinking plenty of fluids can help. Also, doctors can prescribe artificial saliva which comes as a spray to help moisten the mouth. Talk to your doctor about possibly changing the drugs you take so there are less side-effects. Some people find sugar free chewing gum or sugar free sweets help produce more saliva.
