Saliva helps prevent plaque and gingivitis by diluting acids produced by bacteria, limiting bacterial growth and washing away food particles. Saliva also makes your taste buds effective and makes it easier to chew and swallow.

Dry mouth is not a serious medical condition on its own. But in most cases, a symptom of another underlying medical condition that requires treatment. It can also lead to complications, such as tooth decay.

Causes of dry mouth

People get dry mouth due to improper functioning of the glands in your mouth that make saliva. It often results in dehydration. Because of this, there might not be enough saliva to keep your mouth wet. There are several reasons why your salivary glands might not function correctly.

  • Damage to the nerves – An injury that causes damage to your head and neck area can damage the nerves that stimulates the salivary glands to produce saliva. This can result in dryness of the mouth.
  • Chemotherapy – drugs used to treat cancer can make saliva thicker and scanty, causing the mouth to feel dry. This may be temporary with normal flow of saliva returning after treatment is completed.
  • Age – Even though dry mouth is not a natural part of aging but because the aged tend to take more medications for certain conditions. Many of the medications taken mostly cause dry mouth.
  • Medications – Many prescribed and over-the-counter medications causes dry mouth. Medications such as antihistamines, decongestants, anti-hypertensives, depression and muscle relaxants.
  • Medical conditions – some diseases affect the salivary glands. Sjögren’s Syndrome, HIV/AIDS, diabetes, and Parkinson’s disease can all cause dry mouth.
  • Tobacco and alcohol use. Drinking alcohol and smoking or chewing tobacco can increase dry mouth symptoms.
