Why is my mouth sometimes dry?


If you wake up with your mouth feeling like sandpaper, there are many ways you can help to prevent it.


Dry mouth, also known as xerostomia, is a condition in which the salivary glands in your mouth don’t make enough saliva to keep your mouth wet.

It is commonly a symptom of the natural aging process, however there are other causes such as sleeping with mouth open, smoking, radiation treatment, certain medications you may be taking, diabetes and other health conditions. Some medications used to treat conditions such as diabetes can also cause dry mouth.

Your sleeping habits can sometimes be the reason why you may wake up with a dry mouth. It is quite common to wake up with a dry mouth if you sleep with your mouth open. This can occur purely out of habit, blocked nasal passages, or another underlying health condition.

We almost all get a dry mouth at some point, often when we are upset, under stress, or frightened.

However, when your mouth is dry most of the time, it’s very important to take action as this can lead to bad breath, inflammation of the tongue, ulcers, tooth decay, infection, tooth loss and much more.


Common symptoms may include:
– A dry feeling in your mouth, especially your tongue
– Frequent thirst
– Cracked lips or sores in your mouth 
– Difficulty tasting, chewing, and swallowing
– Dry nasal passages, sore throat
– Bad breath


You can do some things to relieve dry mouth temporarily. But for the best long-term dry mouth remedy, you need to address its cause.


Some great ways to help prevent dry mouth are to:
– Stay hydrated by frequently drinking water throughout the day
– Chewing sugar-free gum
– Brush your teeth with a fluoride toothpaste at least twice a day
– If you smoke or regularly consume alcohol, reduce or consider quitting
– Consume caffeine in moderation
– Avoid spicy and acidic foods late in the day
– Practice good oral hygiene habits
