Dry Mouth - Xerostomia
• This can affect many people of all ages and can occur at any time for a variety of reasons.
• Is a common side effect of many prescribed drugs
• Can increase dental decay and oral problems.
• Can lead to difficulties in eating, swallowing and speaking
Why am I experiencing Dry Mouth?
Prescription drugs are one of the most common causes of dry mouth. It is a common side effect of many drugs particularly those used for treating depression, hay fever, nausea and high blood pressure. If you are anxious, depressed or get nervous, this can also reduce saliva flow and make the mouth feel dry. Early morning dryness can be a particular problem for people who sleep with their mouths open in poorly ventilated, centrally heated bedrooms.
Dry mouth may also result from infections, such as mumps, or from dehydration, caused for example by diarrhoea and vomiting, or as an after effect of surgery.
Dry mouth can also be a feature of chronic conditions such as diabetes, Parkinson's Disease and Rheumatoid arthritis.
How could Dry Mouth affect my oral health?
Apart from being uncomfortable, dry mouth has a number of adverse effects on oral health.
• Reduced salivary flow impairs clearance of plaque acid and food debris
• Without the protective effects of saliva to buffer plaque acid, dental decay may progress more rapidly
• There is an increased risk of mouth ulcers and gum inflammation
• The tongue may be smooth, dry or sore
• Thrush or other yeast infections occur more frequently in people with dry mouth.
Your dentist or hygienist can provide advice and dental treatment for any of the complications associated with dry mouth.
