Understanding Xerostomia: Causes, Symptoms, and Relief


Dry mouth, also known as xerostomia, occurs when the mouth produces too little saliva. Despite its seemingly insignificant effects, this condition can have serious consequences for both oral and general health. In order to help you better understand and manage xerostomia, we will explore its causes, symptoms, and treatment in this blog post.

Causes of Xerostomia 

Xerostomia causes include several factors, such as: 


Medication use is one of the leading xerostomia causes. Saliva production can be reduced as a side effect of some prescription drugs like antidepressants, antihistamines, and diuretics. If you are taking medication that is causing your mouth to dry out, talk to your doctor about other options.

Medical conditions

Xerostomia can be a side effect of some diseases or medical conditions. Dry eyes and a dry mouth are classic symptoms of Sjögren’s syndrome, an autoimmune condition. Diabetes, HIV/AIDS, and Parkinson’s disease can also affect saliva production. Consult your doctor if you think you may be experiencing symptoms of any of these conditions.

Lifestyle Patterns

Dry mouth may be caused by a number of our daily behaviors and practices, including smoking, chewing tobacco, drinking excessively, and mouth breathing instead of nasal breathing. 


A dry mouth is a temporary side effect of dehydration. Lack of hydration, excessive perspiration, or other conditions that cause fluid loss can result in a dry mouth. Drink plenty of water throughout the day, especially if the temperature is high or if you plan on engaging in strenuous activity.

Symptoms of Xerostomia

It is important to identify the symptoms and seek appropriate chronic xerostomia. Common symptoms include:

Dryness and stickiness 

Xerostomia is characterized by a chronic dry mouth, which is the condition’s most noticeable symptom. It may feel difficult to eat or speak because your mouth feels dry or sticky.

Difficulty Speaking, Chewing, and Swallowing

A lack of saliva hinders your ability to swallow, chew, and express yourself clearly. This can be unpleasant and may even cause digestive problems.

Bad breath

Saliva aids in the cleansing of the mouth by washing away bacteria. Inadequate saliva flow can cause bacteria to accumulate, resulting in halitosis, or bad breath.

Increased dental problems

Maintaining clean teeth and gums requires saliva. It helps remove food debris and neutralize acids, in addition to protecting tooth enamel. Cavities, gum disease, and other oral infections can spread more easily when saliva production is inadequate.

How Can Xerostomia Be Relieved?

Consider the following options to get relief from Xerostomia:

Stay Hydrated

The symptoms of dry mouth can be reduced by consuming plenty of water throughout the day. To keep your mouth moist, frequently consume water or other drinks without sugar.

Avoid Triggers

One way to get Xerostomia relief is to reduce your caffeine, alcohol, and tobacco intake, as they can worsen dry mouth symptoms. In addition, try to breathe through your nose rather than your mouth in order to retain moisture.

Sugar-free Gum and Lozenges 

Using sugar-free lozenges or chewing sugar-free gum can help with a dry mouth. In order to maintain good oral health, you should seek out products that contain xylitol.

Moisturize the Air 

A humidifier can add moisture to the air in your home or office, making you feel less parched. A humidifier is especially helpful during the colder months or in drier climates.

Oral Hygiene 

When dealing with xerostomia, it is essential to practice regular, thorough oral hygiene. Use fluoride toothpaste, floss once a day, and think about switching to a mouthwash without alcohol if you want healthy teeth and gums. Dry mouth is a common dental problem, but it can be avoided with these measures.

Saliva Substitutes and Prescription Medications 

In extreme cases of xerostomia, your doctor may recommend saliva replacement therapy or medication to increase saliva production. A doctor or other medical expert should be consulted for specific recommendations and care.


Negative effects on oral health and comfort can result from chronic xerostomia. Do not wait to seek professional medical advice if your symptoms do not seem to be improving or if they persist or worsen. They have the knowledge and experience to help you overcome dry mouth and keep your mouth feeling fresh and healthy. Do not feel like your discomfort has to go unnoticed. You can get back to enjoying the sensation of a hydrated mouth with a little help.
