Dry mouth, or xerostomia, may seem like a small problem. But if it happens often, it needs to be taken care of. If you don't treat a dry mouth, it can make it hard to eat, talk, and take care of your teeth in general. Saliva is important for healthy teeth and gums, and enzymes in saliva help break down food. If your mouth is dry all night, it could hurt your oral health without you even realizing it.
