Mouth Dryness: Causes, Signs, and Remedies
Xerostomia, commonly known as dry mouth, is a condition that affects many individuals and can lead to various oral health issues. Characterised by insufficient saliva production, xerostomia can cause discomfort and potentially serious complications.
The most common cause of dry mouth is medication. Many drugs, including antihistamines, antidepressants, decongestants, and anti-anxiety medications, list dry mouth as a side effect. These medications are responsible for approximately 90% of dry mouth cases[1][3][5].
Other causes include health conditions and treatments. For instance, Sjögren's syndrome, diabetes, and certain cancers, as well as treatments like radiation therapy, can cause dry mouth[4][5].
Lifestyle factors also play a significant role. Substances such as tobacco and alcohol can temporarily reduce saliva production, while stress and anxiety can trigger the body's "fight-or-flight" response, reducing saliva production[1].
Older adults are more susceptible to dry mouth due to a natural decrease in saliva production[1][5]. Dehydration, caused by a lack of fluids, can also lead to dry mouth[2].
Mouth breathing and snoring can lead to symptoms similar to dry mouth, especially if the mouth is open for extended periods[1]. Nerve damage to the head and neck area can also result in dry mouth[4].
Treatment for dry mouth depends on several factors, such as whether the person has an underlying condition or disease, or is taking certain medications that may be causing dry mouth. Treatment may include adjusting the dosage of a medication or prescribing another drug that is less likely to cause dry mouth, prescribing medication to stimulate the production of saliva, and treating the symptoms of dry mouth[6].
Xerostomia may be a symptom of a serious systemic disease such as systemic lupus erythematosus, rheumatoid arthritis, scleroderma, sarcoidosis, amyloidosis, Sjögren's, Parkinson's disease, diabetes, hypothyroidism, etc.
Individuals with dry mouth should pay special attention to oral and dental hygiene, including brushing teeth and flossing regularly, plaque removal, and treating gum infections, inflammation, dental cavities, etc. Remedies for dry mouth at home include sipping noncarbonated, sugar-free fluids, chewing gum that contains xylitol, using a carboxymethyl cellulose saliva substitute as a mouthwash, avoiding mouthwashes that contain alcohol, not wearing dentures during sleep, breathing through the nose, using a humidifier to add moisture to a bedroom, and avoiding chewing or smoking tobacco, sugary foods or drinks, acidic foods or drinks, dry food, spicy food, excessively hot or cold drinks, alcohol consumption, and caffeine[7].
