Experiencing dry mouth, also known as xerostomia, is a condition that decreases the production of saliva in the mouth. Saliva plays a crucial role in maintaining oral health by lubricating the mouth, aiding in swallowing and digestion, washing away food particles, and neutralizing acids produced by bacteria. When saliva production decreases, it can lead to a variety of symptoms and complications. These include: a dry or sticky filling in your mouth, difficulty speaking or swallowing, sore throat, dry or cracked lips, bad breath, changes in taste and more!
What Causes Dry Mouth?
Dry mouth can be caused by various factors, including:
Medications:
Hundreds of medications, including antihistamines, decongestants, diuretics, and high blood pressure medication, can reduce saliva production as a side effect. If you are experiencing dry mouth and are are taking a prescription drug, check the label or consult your physician. This is the best way to ensure that this is only a common side-effect of your medication.
Medical conditions:
Certain medical conditions and diseases can cause dry mouth, including diabetes, Sjögren’s syndrome, HIV/AIDS, Alzheimer’s disease and autoimmune diseases. Understanding how these medical conditions cause dry mouth is crucial for diagnosis and management. Addressing the underlying condition is essential for effectively managing dry mouth symptoms.
Aging:
As people age, there may be changes in the salivary glands, which are responsible for producing saliva — leading to dry mouth. The number and size of functional salivary gland cells may decrease over time, affecting overall saliva output.
Dehydration:
Not drinking enough fluids can result in dehydration, which can lead to temporary dry mouth. Saliva is primarily composed of water, and dehydration can lead to reduced saliva production. When the body is dehydrated, it prioritizes maintaining essential bodily functions, and saliva production may be decreased as a result. In severe cases of dehydration, individuals may experience difficulty swallowing due to the lack of lubrication in the mouth.
Mouth breathing:
Mouth breathing is a particularly bad habit to break but one that can have numerous negative impacts to your oral health. Breathing through the mouth instead of the nose can result in dry mouth, particularly during sleep. Not only this, mouth breathing can cause cavities and periodontal disease, and in growing children, mouth breathing can lead to abnormal dental development.
Nerve damage:
Injuries or surgeries that affect the nerves in the head and neck area can disrupt the signals that stimulate saliva production, leading to dry mouth.
Smoking or chewing tobacco:
Here’s yet another reason to break your smoking habit. Tobacco use can dry out the mouth and contribute to dry mouth symptoms. Whether you’re smoking or chewing tobacco, the negative oral health effects are certain.
Stress and anxiety:
When you are stressed or anxious, your body begins to show the effects in many ways! Stress and anxiety can affect the body’s ability to produce saliva, leading to dry mouth symptoms.
Dry mouth, no matter the cause, poses significant risks to dental health, including increased susceptibility to tooth decay, gum disease, and bad breath. Recognizing the symptoms of dry mouth and understanding its potential impact on oral health is essential for maintaining a healthy smile.
If you experience persistent dry mouth, it’s crucial to consult with a dentist or healthcare professional. They can help identify the underlying causes of dry mouth, which may include medications, medical conditions, habitual mouth breathing, or much more. Based on their evaluation, your dentist can recommend appropriate treatment options to alleviate dry mouth symptoms and protect your dental health.
