Dry mouth happens when mouth produces little or no saliva. Dry mouth does not involve only being thirsty but not actually tasting what is eaten or drunk accordingly. That's why there is saliva which enables the sense of taste and the digestion of food. Except from the lack of saliva there are negative implications in the skin as lips become cracked and sores at the corners of the mouth. Tongue can be felt also rough and dry.
Side effects of Dry mouth:
1. Development of persistent bad breath.
2. A lipstick that is worn in the mouth can stick because there is no saliva to rinse it off.
3. Discomfort in the throat due to a tickle.
Causes of Dry mouth:
1. Medicines: More than 400 types of medications can lead to dry mouth as well as the over-counter drugs for allergies and cold symptoms and many prescription drugs for high blood pressure, over-active bladder and mental health problems. Chemotherapy also causes saliva to thicken and make the mouth feel dry.
2. Nerve damage: Certain nerves carry messages between the brain and the salivary glands. If these nerves are damaged then there is disability in the production of saliva. The absence of saliva is critical as without it the taste is hard.
3. Sjogren's syndrome: Autoimmune disorder in which white blood cells called lymphocytes attack the body's tear and salivary glands. This leads to dry mouth and dry eyes.
4. Smoking: Smoking cigarettes, cigars, pipes or other tobacco products encourage mouth to dry.
