What Causes Dry Mouth? Xerostomia Symptoms, Risks, and Treatment in Pakistan

While it may seem like a minor problem at first, having a dry mouth can impact eating, speaking, sleeping, oral comfort and dental health. The medical term for dry mouth is xerostomia, and if it happens frequently, you may have it.

There are many possible dry mouth causes. Some are short-term, like dehydration, anxiety, mouth breathing or a dry environment. Others may be linked to medications, diabetes, autoimmune diseases, cancer treatment or pregnancy.

Knowing the cause is significant because sometimes the symptoms of dry mouth can indicate a health problem. Ongoing dry mouth may also lead to dental caries, gum disease, oral infections, dental decay, and discomfort with dentures.

This guide delves into the most typical causes of dry mouth, symptoms, risks, and dry mouth treatment options to help you understand when it is appropriate to consult a Lahore dentist.

What Is Dry Mouth (Xerostomia)?

A dry mouth can be medically called xerostomia, which often occurs when there is not enough saliva to keep the mouth moist. According to a statement from the National Institute of Dental and Craniofacial Research (NIDCR), saliva keeps your mouth moist, aids the chewing and swallowing process, rinses away food, and buffers your teeth from decay.

Dry mouth in Urdu is called خشک منہ (khushk munh).

Xerostomia is a useful term to differentiate from hyposalivation. Xerostomia is a patient's self-perceived dry mouth, and hyposalivation is a reduced salivary flow. Sometimes someone will feel dry even when his or her saliva flow is not significantly decreased.

Dryness from time to time is not a cause for concern. But if your mouth is dry for weeks, wakes you at night repeatedly, makes eating hard, or if you experience other symptoms, you need professional attention.

What are the Causes of Dry Mouth?

There is no one cause of dry mouth. The cause may differ based on age, taking medication, health status, lifestyle, time of day or whether it occurs occasionally or regularly.

Some of the more common triggers for dry mouth are dehydration, side effects of certain medications, anxiety, mouth breathing, cancer therapy, diabetes, and certain autoimmune disorders, like Sjögren's disease. These are drugs which decrease the flow of saliva. These are drugs that reduce saliva production.

One of the most common causes of xerostomia is medication. Numerous medications may affect saliva flow or cause a change in the sensation of the mouth.

Some medications that increase a person's likelihood of getting dry mouth include:

• Antihistamines

• Antidepressants

• Antihypertensives

• Diuretics

• Decongestants

• Certain analgesics and other drugs that have a drying effect

According to the American Dental Association, xerostomia is especially prevalent, and there is a higher risk when a person is on several medications.

Do not self-discontinue a prescribed medicine if you think it may be causing the problem. Your doctor or dentist can check what medicines you are taking and determine if you need to change your medicine, adjust your dose, or manage your symptoms.

Medical Conditions Linked to Dry Mouth

Persistent dry mouth can be a symptom of several medical conditions.

Dry mouth may be a result of diabetes mellitus, especially if blood glucose levels are not well controlled. Diabetics are also more susceptible to gum disease and oral thrush.

Sjögren's syndrome (now known as Sjögren's disease) is an autoimmune disorder that involves the immune system attacking the glands that make tears and saliva. One of the most important clues is whether the person complains of dry eyes and dry mouth.

There are other medical factors that may also be responsible, as well as hypothyroidism, anemia, acid reflux/ GERD, salivary gland disorders and certain infections. However, dry mouth does not always indicate that it is a symptom of one of these conditions, and a diagnosis should be based on the overall clinical presentation.

Dry mouth may be caused by:

Dry Mouth and Diabetes

Dry mouth and diabetes do have a connection. Dry mouth may be a complication of diabetes or caused by a decrease in saliva production, which may lead to tooth decay, soreness, oral infections and thrush. Individuals with diabetes are also at an increased risk of periodontal disease, especially if their blood glucose level is not under control.

Dry Mouth and Frequent Nighttime Urination

A persistent dry mouth, increased thirst and frequent urination, particularly waking up several times at night to urinate, is a combination that is particularly noteworthy.

High blood glucose can cause someone to urinate a lot and feel thirsty a lot. Dry mouth is not a diagnostic sign of diabetes, but if it is accompanied by these symptoms, especially if the person was not previously diagnosed, consulting a health care provider about the possibility of diabetes is prudent.

If you have diabetes, it's especially crucial to have regular dental checkups, as health problems from diabetes can make it easier for you to develop gum disease, thrush and other oral issues.

Dry Mouth During and After Cancer Treatment

One of the main causes of xerostomia is cancer therapy. Head and neck radiation therapy may lead to damage of the salivary glands and cause significant loss of saliva. Dry mouth or thicker saliva may also occur from some chemotherapy drugs. These effects can happen while you are being treated for the condition, and they can last after treatment (depending on the treatment).

A decrease in saliva makes you more susceptible to tooth decay, gum disease, infections, trouble swallowing, and other oral complications.

Ideally, the oral health of patients who will be receiving cancer treatment should be evaluated prior to treatment. Dental evaluation prior to cancer treatment and communication between the dental and cancer-care teams are recommended by NIDCR.

For those entering chemotherapy or a family member, you can also find out more about dental care before chemotherapy.

It is particularly critical to monitor patients' mouths after cancer treatment when they still experience xerostomia.

Dry Mouth and Pregnancy

During pregnancy, there can be many hormonal and physiological changes that might result in an increase or decrease in thirst, saliva production, taste, gums or oral comfort.

However, a completely dry mouth is not a sure indicator of pregnancy. This can also occur due to dehydration, nausea and vomiting, mouth breathing, changes in what you eat, anxiety or a reaction to medications.

When the patient is pregnant, it is important to make sure the patient is hydrated, that good oral hygiene is maintained, and dental care is taken, but not the assumption that a dry mouth means it is pregnant. Regular dental care can help to detect gum inflammation, tooth decay and other oral issues at an early stage if you are pregnant or planning to get pregnant.

To get more information on Dental Care during Pregnancy, please refer to our Dental Care during Pregnancy Guide for Lahore patients.

If symptoms of dryness are continuing and you also have unexplained fatigue, are urinating a lot, have dry eyes, do not want to swallow, are experiencing swelling or other persistent symptoms, you may need a medical evaluation.

Lifestyle, Diet, and Situational Causes

Not all dry mouth causes are medical diseases. Often caused by dehydration, which can occur following physical exertion, excessive sweating or vomiting, diarrhea, fever or a lack of fluid. Mouth breathing can also cause dry mouth, especially if due to nasal blockage, allergies, snoring or open mouth breathing. A sense of dry mouth can be caused by changes in saliva flow that occur as a result of anxiety and stress.

Diet can play a role, too. A high intake of caffeine, alcohol, extremely salty foods, acidic foods and foods that cause a dry mouth can worsen symptoms. With a keto diet, some individuals might experience increased thirst or dryness, especially with changes in fluid and electrolyte levels. Dry mouth can be worsened by smoking and drinking alcoholic beverages.

Another factor for people with sensitive mouths is toothpaste. A few toothpastes contain the foaming agent sodium lauryl sulfate (SLS), some of which may irritate or dry out the lining of the mouth in certain people. Toothpaste that does not produce foam when it foams may be better for individuals who have a dry mouth.

Dry Mouth Symptoms and Warning Signs

Dry mouth caused by a high fever shouldn't just be chalked up to a normal lifestyle cause. Dengue is an important acute disease to consider in appropriate outbreaks/exposures in Pakistan. Fever and fluid loss may also lead to dehydration, and WHO recommends that dengue sufferers have lots of fluids, rest and get medical attention. Signs of severe dengue are extreme thirst, severe abdominal pain, persistent vomiting, bleeding, rapid breathing, weakness and other worrisome symptoms.

If you are experiencing fever and probable signs of dengue (increased thirst/ dehydration), please consult the doctor; home remedies to treat dry mouth are not advised.

Dry Mouth Signs and Symptoms

The most common dry mouth symptoms include a sticky or dry sensation in the mouth and a sense of thirst. However, xerostomia can have a much more significant impact than on comfort.

Common symptoms include:

According to NIDCR, difficulty chewing and swallowing, tasting, speaking, cracked lips, mouth sores, recurrent infections, and bad breath are symptoms of dry mouth.

So, what is dry mouth a sign of? It can be a lack of fluid or mouth breathing at times. In other instances, it may be associated with medication, diabetes mellitus, Sjögren's syndrome, chemotherapy, or other illness.

The chronicity matters. Having mouth dryness after exercising or an overstress event is not a persistent xerostomia that occurs despite drinking plenty of fluids.

Why Is My Mouth Dry at Night or When I Wake Up?

Dry mouth is often noticed at night or in the morning. Saliva production decreases during sleep, and mouth breathing can contribute to dryness. It can be caused by a blocked nose, allergies, snoring, mouth breathing, dehydration, or some medications.

Your bedroom can also be a factor. The feeling can be exacerbated by dry air, especially during air conditioning. If you have a very dry mouth every morning, consider if you also have:

• Stuffy nose or trouble breathing through the nose

• Loud snoring

• Excessive nighttime thirst

• Frequent nighttime urination

• New medication use

• Persistent daytime dryness

A humidifier will not correct an underlying medical cause; it will only help to make the bedroom more comfortable during wetter weather periods.

Dental Risks of Untreated Dry Mouth

Saliva is not just "water in the mouth. Aids in lubricating tissues, assisting with swallowing, removing food particles from the mouth, promoting oral health and protecting teeth.

The mouth's protective functions are lessened when saliva is continually depleted. According to the ADA, xerostomia can lead to a higher risk of dental caries, tooth sensitivity, demineralization and oral infections.

1. Tooth Decay and Cavities

If there is not enough saliva, the acids and food particles can stay around teeth longer. This can make it more likely that you will develop cavities or damage to the enamel.

Those with a chronic dry mouth may require a more preventive approach to dental care than a person with normal saliva production.

1. Gum Disease

However, dry mouth does not necessarily lead to gum disease, but it can lead to an unhealthy oral environment. If xerostomia is combined with diabetes, smoking, poor oral hygiene or existing plaque, the risk of the conditions can be increased.

1. Oral Thrush and Infections

Oral thrush is a fungal condition which may be more likely to develop when the normal defenses in the mouth are compromised. Risk factors may include diabetes, cancer treatment, dentures and dry mouth.

If you see continual white spots, burning, pain or trouble chewing, a dentist or physician should determine the cause, not the fact that it is dry mouth.

For more information, read our adult oral thrush overview.

1. Denture Discomfort

Saliva lubricates tissues and adds to the comfort of the denture. Dentures might not be as comfortable if the mouth is dry, and it is harder to eat or talk.

1. Bad Breath

When your mouth is dry, you're more likely to have poor oral hygiene thanks to the fact that saliva typically helps wash away food particles and keep your mouth healthy.

If a person has ongoing bad breath that doesn't seem to be going away after they brush their teeth and clean the back of their tongues, they should get a dental checkup to find out if they have dry mouth, gum disease, tooth decay, infection, or another problem.

Home Remedies and Self-Care for Dry Mouth

Simple steps can help relieve occasional and mild dryness.

These are all common recommendations: drinking water regularly, chewing sugar-free gum, using sugar-free lozenges, and keeping the mouth clean. For people who are able to chew gum, sugar-free gum (with xylitol) may be beneficial, as it produces saliva and won't add sugar to the diet.

If the air is dry, it may help to place water close to the bed and use a humidifier at night. Rather than continually drinking water, it may be more beneficial to treat the nasal issue if it is responsible for mouth breathing.

Avoid factors that could exacerbate dryness, such as:

• Smoking and tobacco

• Alcohol

• Excessive caffeine

• Foods that are very salty, spicy, acidic or sugary

• Alcohol-containing mouthwash

Brush with fluoride toothpaste and floss regularly for dental protection.

What about Homeopathic Remedies?

Dry mouth is sometimes used in the marketing of a homeopathic product; however, it doesn't replace an underlying diagnosis or treatment.

No good evidence exists for any one homeopathic remedy, in particular, to restore normal salivary gland function. If you have a persistently dry mouth, particularly if you have other symptoms or dental issues, it is more beneficial to determine what is actually causing your dry mouth than to continually experiment with various remedies that have not been proven.

The type of dry mouth treatment is determined by the cause of the dry mouth, the severity of the dry mouth symptoms, whether the salivary glands are still functioning, and if complications have occurred such as tooth decay or infection.

Fluoride Treatments

Persistent xerostomia can pose a risk for tooth decay and is especially important when fluoride is involved.

Your dentist might suggest using fluoride toothpaste, a fluoride application by a dentist, or another fluoride-containing preventive treatment based on your dental risk.

Artificial saliva and stimulants.Artificial saliva and saliva stimulants. Oral gels, sprays and other moisturizing products, and also saliva substitutes, can help to ease the symptoms temporarily. They do not always restore normal salivary gland functioning, but they can make eating, speaking and sleeping more comfortable.

If the salivary glands are still working, sugar-free gums or lozenges can help to stimulate saliva. In cases where symptoms are severe, your doctor or dentist may also recommend a saliva stimulant (where appropriate). Prescription medication should be used after professional evaluation only for certain medications.

When to See a Dentist About Dry Mouth

With persistent, worsening or interfering with life dry mouth, a dental appointment should be considered.

If you have any of the following, then a professional assessment is especially important:

• Trouble eating, chewing or talking

• Ongoing mouth pain or burning

• Recurrent oral infections/white patches

• New or recurrent caries lesions

• Swollen and bleeding gums

• Persistent bad breath

• Denture discomfort

• Dry throat and dry eyes

• Xerostomia (dry mouth) and polyuria (excessive urination) or thirst

• Symptoms that persist after enough fluid and self-care

Your dentist will check the health of your teeth, gums, tongue, tissues, dentures and the amount of saliva in your mouth and decide if more medical testing is needed. Medical history, medication review, exam and sometimes blood tests or salivary-flow testing may be used to diagnose.

Why Choose Dental Aesthetics for Dry Mouth Treatment

Knowing the causes of dry mouth responsible for your issue is more beneficial than treating the symptom over and over without realizing its origin.

In some instances, the treatment is as simple as staying hydrated, avoiding breathing through the mouth, using a non-irritating oral care product or working on sleep habits. However, in some cases, dry mouth may be associated with taking medications, diabetes, Sjögren's syndrome, cancer treatment or other health conditions requiring treatment from a healthcare professional.
