I've had dry mouth for a few years and tried many products from mouthwashes to oral gels to prescriptions. OraMoist is a new idea. It's a patch that sticks on the roof of the mouth and dissolves over time and it increases the amount of moisture in your mouth. It worked very well and longer than other products I've used. It seems there's no one thing that gets rid of dry mouth 24 hours a day. But OraMoist will become a regular product for me. A little downside is that at first, having a patch on your mouth is strange. But it doesn't interfere with anything so you forget about it.
