Treatment of Dry Mouth (Xerostomia)

Introduction to Dry Mouth Treatment

The American College of Rheumatology recommends measuring baseline salivary gland function before initiating treatment for dry mouth, then following a stepwise approach based on the severity of the dysfunction 1, 2

The American College of Rheumatology suggests that whole salivary flow rates should be measured to objectively determine glandular function, as subjective feelings of dryness may not correlate with actual salivary output 1, 2, 3
The American College of Rheumatology advises against relying solely on patient-reported symptoms to guide treatment selection, as this can lead to inappropriate therapy choices 1, 2

For patients with mild glandular dysfunction, the American College of Rheumatology recommends non-pharmacological salivary stimulation as the preferred first-line approach, using sugar-free gum, xylitol lozenges, or other gustatory stimulants 1, 2, 3
The American College of Rheumatology suggests that xylitol-containing products offer dual benefits, stimulating saliva production while protecting against dental caries 3, 4

For patients with moderate glandular dysfunction, the American College of Rheumatology recommends pharmacological stimulation with muscarinic agonists, such as pilocarpine 5 mg orally four times daily 1, 2, 5
The American College of Rheumatology notes that the dose of pilocarpine can be increased to 30 mg/day for improved efficacy, but warns of potential side effects such as excessive sweating, nausea, and bronchoconstriction 5

For patients with severe glandular dysfunction, the American College of Rheumatology recommends saliva substitution as the preferred therapeutic approach, using products with neutral pH containing fluoride and electrolytes 1, 2, 5
The American College of Rheumatology suggests that methylcellulose/hyaluronate-based substitutes are preservative-free and particularly useful, and that xylitol-containing oral sprays provide temporary symptomatic relief plus protection against dental caries 4, 5

The American College of Rheumatology recommends increasing water intake throughout the day to maintain oral moisture, limiting caffeine consumption, avoiding crunchy or spicy foods, and using specialized toothpastes and rinses designed for dry mouth 3, 4

The American College of Rheumatology warns that untreated severe dry mouth can lead to dental caries and tooth loss, and recommends prescribing fluoride rinses or gels for all dentate patients with xerostomia to mitigate caries risk 4, 5

The American College of Rheumatology recommends referring patients for specialty consultation or dental evaluation when symptoms are severe and persistent, significantly affect quality of life, or signs of dental complications appear 3, 4
