The subjective sensation of dry mouth or xerostomia is a common symptom and estimates of the prevalence vary from 10-50%.  The Cochrane Collaboration published systematic  of topical treatments for reducing the effects of dry mouth in 2011(Furness et al). Recently the American Dental Association’s Evidence-based Dentistry Center have published a critical summary of this review

The summariser notes that the review was of high quality, although, because of the range of interventions and variety of outcome measures only limited meta-analysis could be performed. The review included 36 trials in all, 17 of which were of high risk of bias. 18 of unclear risk  leaving only 1 with a low risk of bias.  Many of the trials also included only a small number of participants.

Overall the review found no strong evidence that any topical therapy is effective for relieving the symptom of dry mouth.
