Why Is My Mouth So Dry?

A dry mouth can be annoying. If this problem is not taken care of, it can create inopportune difficulties in daily routine. But what are the reasons for this inconvenience? This condition is known as xerostomia, it has various causes, and you can learn about them here. So, if you have this problem frequently, check this article carefully.

The Importance of Saliva

Dry mouth or xerostomia is accompanied by various symptoms. Among the main ones you may notice as:

  • The presence of cavities
  • Cracked or dry lips
  • Dry throat
  • Bad breath
  • Problems swallowing food or liquids.

However, the main problem occurs when the salivary glands do not produce enough saliva to maintain moisture in the mouth. Saliva is what allows the main functions of the oral cavity to be carried out. These are: such as chewing, swallowing, tasting, and speaking.

If not enough saliva is produced, the mouth dries out, and plaque builds up. This will bring the unwanted consequences that we know, such as caries or even gingivitis.

So, saliva helps prevent tooth problems by neutralising acids produced by bacteria, limiting bacterial growth, and removing food particles. Saliva also facilitates both chewing and swallowing. In addition, it helps digestion.

Because of this, low saliva production and dry mouth can significantly affect your overall health.

Causes of Dry Mouth

 Wondering about the reasons that can cause your mouth to dry? Here we bring you the three most common causes of low saliva production and dry mouth.

Drink an insufficient amount of water

Water intake will depend on your body characteristics, such as weight and age. But also depends on your daily activities, routine, and even the weather and where you are. But in general, at least two litres minimum of daily water intake is recommended.


Some medications can cause dry mouth. The most common are: antihistamines, anxiolytics, muscle relaxants, and some painkillers. It is necessary to take preventive measures regarding your water intake when consuming medications.


The residues that remain in the mouth when smoking cause the slowing down of saliva production. Along with halitosis, this is one of the most common problems among smokers.


Other reasons, less common but just as important, for which there may be dry mouth are certain oral diseases such as oral candidiasis. There is also diabetes and Alzheimer’s, autoimmune diseases such as AIDS, HIV, and strokes. 

Finally, there are relatively common habits that can also increase the symptoms of dry mouth. For example, consuming alcohol. Snoring and mouth breathing can also contribute to dry mouth.

In any case, the good news is that the moisture in the mouth can be restored. In addition, your dentist may recommend mouthwashes specially formulated for dry mouth.

In the meantime, make sure you’re consuming the right amount of water and cutting back on beverages like coffee, tea, and sodas.
