Treatment for dry mouth depends on several factors such as whether the patient has an underlying condition or disease, or is taking certain medications that may be causing dry mouth.
Medications: If the dry mouth is thought to be
caused by a particular medication, the doctor will either alter the dosage or prescribe another drug which is less likely to cause it.
Stimulating saliva production: Medication
may be prescribed to stimulate the production
of saliva, such as pilocarpine (Salagen) or cevimeline (Evoxac).
Experts say that symptomatic treatment for dry mouth typically includes four areas:
- increasing the flow of saliva
- replacing lost secretions
- controlling dental caries
- specific measures, such as treating infections
A person with dry mouth should pay special attention to oral/dental hygiene. This includes plaque removal and treatment of gingival infections, inflammation, and dental caries. Brushing teeth and flossing regularly is important.
The doctor or dentist will probably examine the patient’s mouthTrusted Source and review their medical history. Blood tests and imaging scans of
the salivary glands may also be ordered.
Sialometry: This is a simple procedure that measures the flow rate of saliva. Collection devices
are placed over duct orifices of the saliva glands,
and saliva production is stimulated with citric acid.
Saliography: This is a radiographic examination of the salivary glands and ducts. It may be useful in identifying salivary gland stones and masses.
Biopsy: A small sample
of salivary gland
tissue is taken. Often used in the diagnosis of Sjögren’s syndrome. If malignancy
(cancer) is suspected,
the doctor may also order a biopsy.
Many doctors report that often, even though the patient complains of severe it , the oral mucosa appears to be moist. Less frequently, it may be the other way round – the oral mucosa appears dry, but the individual does not complain of its symptoms.

Experts say that xerostomia
is usually caused
by inadequate function of the salivary glands.
An individual with xerostomia typically finds it harder to enjoy food.
