What is Dry Mouth?
Dry mouth (or xerostomia) affects at least one in five adults. It happens when there is a lack of saliva, or spit, in the mouth. This is usually because your salivary glands aren't working properly.
Its easy to take saliva for granted but it has lots of important roles in the mouth - moistening food and so making it easier to chew and swallow, helping kick start our digestive processes, protecting teeth from decay and helping sores to heal.
What are the symptoms of dry mouth?
While lots of us may experience a dry mouth occassionally, some people suffer all the time. It not only feels unpleasant but it can affect quality of life. Symptoms can include:
- A dry or sticky feeling in the mouth
- Thick, stringy saliva
- A painful or burning sensation affecting the mouth and tongue
- Dry, cracked painful lips
- Bad breath
- Difficulty in eating - especially with dry foods such as cereals
- Difficulty in swallowing or speaking
- Discomfort when wearing dentures
- Feeling thirsty - especially at night
What causes dry mouth?
There are many different causes including diseases of the salivary glands such as Sjogren's syndrome (where the body's immune system attacks the salivary glands) and sarcoidosis (a disease causing inflammation of the body's tissues), some cancer treatments, dehydration (seen in people with diabetes or kidney problems) and anxiety.
Medicines can also cause dry mouth - perhaps surprisingly, over 400 different drugs have this as a possible side effect. The more medicines some one takes, the greater the chance they will suffer. Some common medicines include :
- Certain heart medicines
- Drugs to manage mental illness
- Drugs for epilpesy
- Anti-sickness medcines
- Antihistamines - in some allergy treatments but also some sleep aids
- Srong pain relivers such as morphine
If you are taking several medicines at a time and you are suffering from dry mouth, you may want to discuss it with your doctor or pharmacist. They may not be aware how dry mouth affects you and can review your medication.
