Dry mouth (xerostomia)
On causes, remedies & treatments of inadequate natural production of saliva

The major importance of proper salivary flow has been discussed at Tooth remineralisation & demineralisation, saliva & pH: 5 major prerequisites for dental health and stopping & reversing tooth decay. The following lists possible reasons for a lack of salivary flow as well as natural remedies and treatment suggestions.
Causes of dry mouth
- Dehydration
An obvious cause with an equally easy remedy. - Mouth-breathing
- Medications and supplements
may cause dryness of mouth. Eyedrops (prescribed for instance against allergies) and some or all painkillers as well as antihistamines and decongestants contain substances that hinder/impact salivary production. - Chemotherapy or radiation treatment1 to the neck/head area, incl. dental x-rays5
- Medical conditions
Some diseases (such as certain [rather rare] auto-immune disorders) seem to be associated with inadequate saliva flow. - Acute stress
A strong feeling of fear can dry the mouth to the point that speaking becomes virtually impossible.
Dry mouth natural remedies and treatments
- Increase fluid intake
- Use xylitol or chew xylitol gum2
- Discontinue medicinal drugs (unless you think you depend on them)
- Practice oil pulling3
- Destress4.
