Are you suffering from dry mouth?

July 18, 2017


Dry mouth, or ‘xerostomia’ is a condition in which the salivary glands in your mouth don’t make enough saliva to keep your mouth wet. Some may think that dry mouth is a normal part of aging but it isn’t.  However, tends to be more commonly found in older adults, mainly due to the number of medications older people may be taking.


Why do we need saliva?

Saliva protects and lubricates our mouth. It also:


What causes dry mouth?

We all may get a dry mouth during the night, first thing in the morning, when we are stressed or when we are exercising in the heat. This is quite normal but there are other causes of dry mouth and these include:


How is the dry mouth managed?

Management offered by your GP

Treatment for dry mouth depends on whether the cause is an underlying condition or disease, or induced by the medication that you are taking. If an underlying medical cause is found, your GP may try to manage the condition effectively to reduce or alleviate the symptoms. If a certain medication is the cause your GP may need to alter the dosage of the medication or even change the drug which may be responsible for the dry mouth. In more severe cases, the GP may decide to prescribe special medication to stimulate the production of saliva.


Management offered by the dentist

A patient with xerostomia should pay special attention to their oral and dental hygiene. This includes effective tooth brushing and interdental cleaning to remove plaque.  The dentist will assist with the treatment of gum infections, inflammation, and dental caries (decay). Brushing teeth and flossing regularly is really important.

  1. Teeth: Lack of saliva also increases the risk for tooth-decay. Frequent dental examinations – twice a year and radiographs X-rays every 1 – 2 years, will reveal any cavities. The progression of decay in a dry mouth may be very fast and therefore the dentist may suggest that you should use prescription only high fluoride toothpaste (Duraphat 5000) to decrease your risk of getting decay or even suggest a fluoride varnish application.
  2. Gums: The lack of saliva increases the susceptibility for gum infections. Daily tooth brushing and interdental cleaning to remove any plaque from the teeth is extremely important. Frequent visits to the dental hygienists (2 to 4 times a year) are recommended to improve and maintain your gum health.
  3. Mouth Mucosa, Tongue and Lips: Difficulty swallowing food, changes in the sense of taste, a burning sensation or pain in the mouth and difficulty talking are some of the most severe symptoms of dry mouth. The dentist may suggest you use products which act as artificial saliva, saliva substitutes or oral moisturisers to alleviate or prevent such symptoms. Saliva substitutes are used as often as needed and although they do not cure dry mouth, they can provide temporary relief of symptoms. Alcohol-free mouth rinses, lozenges, and moisturizing oral sprays and gels are available as over the counter products for the care of dry mouth.
  4. The dry environment in the mouth makes mouth infections easier to occur. Hence, any dentures should be kept out at night-time and cleaned properly to avoid any fungal infections of the roof of the mouth or corner of the lips (candidiasis). The dentist and dental hygienist will be able to diagnose these infections and offer you appropriate advice.
