Article in English: One of the quickest and easiest ways to produce more saliva is to pop a stick of gum in your mouth and chew it. The chewing action tells your body that you are eating and that you need saliva to process your food.  It's a good idea to chew sugar-free gum if you have a problem producing saliva. The health of your teeth is already at risk from not having enough saliva, so introducing a bunch of sugar into your mouth potentially adds to the problem. Xylitol sweetened gum or candy is a good option that will help you avoid cavities. Sucking on something that is a bit tart or sweet can cause your salivary glands to kick into action. However, consider using something sugar free, such as sugar free mints, so that you do not damage your teeth. Try choosing a sucker, candy, or lozenge that is a bit tart. The tartness will stimulate the glands really well. When fighting off dry mouth, it's important to keep enough moisture in your body. Drink water throughout the day so that your system is hydrated, your mouth stays moist, and mucus in your mouth is loosened. One way to moisturize your mouth immediately is to drink something. Drinking things physically moisturizes the mouth but it also kick starts saliva production. Don't pick a beverage that contains alcohol or caffeine. These can both inhibit saliva production. There are a variety of foods that are good at stimulating salivary glands to start producing saliva. This is due to their texture, sugar content, acidity, or bitterness. They include:  Apples Hard cheeses Crunchy vegetables Citrus Bitter greens
