The best way of relieving the symptoms of Xerostomia (Dry Mouth) will largely depend on the cause and severity. Mild, short-term Dry Mouth can be helped by chewing sugar-free gum, limiting caffeine and alcohol intake, avoiding smoking and keeping well hydrated. However, for many people these actions alone are not enough and a saliva substitute (also referred to as a Dry Mouth spray) can be prescribed. It is important to choose a spray that not only offers good lubrication but is also mild tasting and pH neutral. Many commercially available products for Dry Mouth, including some sprays and gels are actually acidic. Finding a product that is pH neutral is crucial, as any rise in the acidity levels in the mouth can increase soreness and contribute towards further tooth decay.
