Dry mouth is often a much-overlooked symptom that can be really irritating. It can be caused by a disease itself, by side effects of medication, or symptoms of something quite minor. Either way, it's an annoying symptom that can interrupt the most mundane tasks.
Talking becomes difficult, singing is almost impossible, and drinking water almost never quenches this kind of thirst. The only way to really improve this symptom is by encouraging your own production of saliva. That is what xylitol does.
The Lighter Side of Dry Mouth is that there are products out there that really help. It also encourages you to drink more water - which is rarely a bad thing. More water overall is something we could all use.
Some of the products out there include Xylitol Tablets - these are usually fruit or mint flavoured and can be found at pharmacies and often at dental offices. Xylimelts are mint-flavoured tablets that have a melting edible backing that actually sticks to your teeth/gums. So you press down on the tablet on the face of a back molar (so no one can tell), and it increases saliva without being uncomfortable. Plus, it acts as a breath freshener..
Then, there are many types of gum that contain Xylitol. Trident Vibes is a new one that I am aware of.
*Just be careful to keep these products away from your pets, as Xylitol is very unsafe for pets.
