Herbal Therapy

• Herbal remedies are known to be great ways to increase saliva flow. Ginger and Chinese green tea are two of the most widely used therapies for dry mouth at night and have been proven to work when taken in intervals. These drinks help increase salivary flow to the mouth but have to be taken periodically throughout the day. They help keep your mouth moist from dusk till dawn, and it helps to drink a cup right before you hit the sack.
  
  

Drinking Lots of Water

• When most people suffer from dry mouth, the first thing they think of doing is getting a drink, the problem is they usually get the wrong drink. Most drinks have sugar and syrup that just dry your mouth out over time. Water is the best option to quench your thirst. It has no added sugars and sweets, and it simply moisturizes your mouth without adding any extra gunk that may be detrimental to your dry mouth. Drink throughout the day and have a cup next to your bed as you fall asleep.
  
  

Finely Crushed Ice

• Right before you go to bed, you can get a cup of finely chopped ice and let it melt in your mouth as you fall asleep. This is similar to water, except it takes longer for the water to melt so it sits in your mouth longer and soaks into the tongue and gums. Use the grounded ice option on your re-refrigerator for a perfect cup of dry-mouth medicine.
  
  

Sugar-Free Gum and Candy

• If you like to eat candy and chew gum throughout the day, make sure it's sugar free. Sugar is a dry mouth's worst enemy, it sits in the mouth and soaks up all the moisture that drips by. Sugar-free gum and candy will create saliva in your mouth, without giving you a ton of sugar to soak it all back up.
  
  

Use a Room Vaporizer When You Sleep

• One of the problems that causes dry mouth is the area you're living in. If you're living under dusty, dry and hot conditions, you're more likely to suffer from dry mouth. The air that you're breathing in has no moisture so it just dries up your breath as you snore the night away. A room vaporizer will put some mist in the air and some moisture in your mouth.
  
  

Artificial Saliva Substitute

• Many saliva substitutes have been approved by the FDA and are available over the counter at your local pharmacy. The product is used just as a mouthwash and offers immediate and effective relief of dry mouth. Most brands are under $10, so a swig right before bed every night may be worth a try.
