  • Chronic diseases such as Sjogren’s Syndrome and certain other medical treatments are also responsible for an alteration in saliva production.
  • Typical examples of medical treatments which affect dry mouth may include bone marrow transplants, radiation treatment, specifically for head or neck cancer or the removal of salivary glands, which can lead to a progressive onset of this condition.

Relieve your symptoms

Saliva is key to a healthy mouth. Without adequate saliva you can develop tooth decay and other more serious conditions.

Simple steps can be taken to diagnose the problem and relieve symptoms.

Why care about dry mouth?

Lack of saliva, which contains protective minerals and proteins, can result in tooth decay, especially near the gum line and crown margins, and infect your gums.

What causes dry mouth?

  • Prescriptions that help depression, asthma, bladder control, blood pressure, some neurological diseases as well as some over-the-counter medicines to alleviate allergies, colds and coughs.
  • Chronic diseases such as diabetes, ectodermal dysplasia, hepatitis C, sarcoidosis and Sjogren’s Syndrome, amongst many other increasing medications and conditions, are now being identified as contributing to a reduction in healthy saliva.

What steps can you take to alleviate your discomfort?

  • Drink additional fluids which do not contain sugar.
  • Still water is best.
  • Use sugar-free gum to stimulate saliva flow.
  • Visit your dentist more frequently than every six months to address your increased risk of tooth decay.
  • Consume food and drinks with a low pH.

Acid sources from inside the mouth.

Gastric Fluid. This can be caused by a condition known as GORD(GERD) Gastroesophegeal Reflux Disease. This is a disease where gastric fluid from the stomach comes in contact with the teeth causing erosion and commonly occurs during sleep. People who suffer from Bulimia and Anorexia Nervosa can experience very significant tooth erosion similar to GORD(GERD) patients.

Habits and behaviors that cause erosion.
Excessive tooth brushing with abrasive toothpastes and habits such as swishing of acidic low pH drinks or biting lemons can increase the acidic content of oral fluids. Teeth subject to acid erosion can also significantly contribute to the tooth wear caused by tooth grinding or Sleep Bruxism due to removal of the harder outer enamel surface.
