Twice daily brushing of a toothpaste containing 4% betaine by weight in persons with dry mouth symptoms appears to be able to reduce said symptoms as assessed by self-reported, with no apparent changes in the visual appearance of the mucosa or bacterial colonies. Efficacy was greater in those with worse symptoms and lower baseline salivation rates.
