A dry mouth can be uncomfortable, even painful, but you already know that. What you may not know is that a dry mouth means your risk of getting cavities is very high. First-things-first, Allday spray feels and flows like natural saliva providing immediate relief from dry mouth. But there’s more. Allday spray contains 44% xylitol (much more than any other brand) in a non-acidic formula that helps maintain a healthy oral environment, which is essential for preventing cavities. Patented Allday spray fights dry mouth differently than any other moisturizing mouth spray. Its maximum xylitol concentration and unique hydrogel mimic natural saliva, keeping moisture and the high level of xylitol in your mouth longer. Your dry mouth may be more (or less) severe than others. The good news is that you can use Allday spray as often as you like, to provide relief all day and night long.
