A dry mouth means your mouth does not make enough saliva. Saliva helps you eat, talk, and keep your mouth clean. Without it, your mouth feels dry, sticky, or sore. Many people drink water but still feel dry. This guide explains what dry mouth is, what causes it, what symptoms to look for, and how to treat and prevent it.
What Is Dry Mouth or Xerostomia?
Dry mouth—also called xerostomia— means the mouth does not have enough saliva. Saliva protects teeth and helps with eating and talking. Without saliva, the mouth becomes dry and sore, the tongue may feel rough, and lips may crack. Dry mouth can lead to infections and other problems if not treated. Plus, Dry mouth can lead to more cavities, which may cause you to need a root canal.
What Are the Symptoms of Dry Mouth?
Here are the symptoms of dry mouth:
- Your mouth feels dry or sticky.
- Your throat feels dry or sore.
- Your tongue feels rough or dry.
- It’s hard to chew, swallow, or talk.
- Your lips get cracked.

Why Do I Get a Dry Mouth Even after Drinking Plenty of Water?
A dry mouth can still happen even if someone drinks a lot of water. Water does not fix the problem if the body does not make enough saliva. The main reasons include:
- Taking some medicines can make your mouth dry.
- Having health problems like diabetes or Sjögren’s syndrome can reduce spit.
- Breathing through your mouth, especially while sleeping.
- Smoking or using any kind of tobacco.
- Feeling stressed, anxious, or nervous often.
- Getting older can change how your body makes saliva.
- Undergoing cancer treatments like radiation or chemotherapy can damage spit glands.
- Having an injury or surgery near the head or neck can hurt the nerves that control saliva.
- Drinking too much alcohol or caffeine can dry out your mouth.
- Not drinking enough fluids during the day can still cause dehydration.
Note: Severe tooth decay from dry mouth may lead to treatment like a root canal if the damage reaches the tooth nerve.
