What Causes Dry Mouth And How to Treat It Effectively

Published date field

Ever wake up with a dry, sticky mouth that makes swallowing uncomfortable? Or find yourself constantly sipping water, yet the dryness just would not go away? You are not alone. Dry mouth, or xerostomia, happens when your mouth does not produce enough saliva, leading to discomfort, bad breath, and even an increased risk of cavities.

Read on to understand what causes dry mouth, its symptoms, risk factors, and effective treatments. Whether you are experiencing dry mouth at night or throughout the day, knowing the right remedies can help you find relief and keep your oral health in check.

What is Dry Mouth?

It is common to have the thought, “Why does my throat feel dry?” even after drinking water. That uncomfortable dryness in your mouth or throat is known as dry mouth. It is medically referred to as xerostomia. When your salivary glands do not produce enough saliva to keep your mouth moist, it leads to discomfort, difficulty in swallowing, and even bad breath.

Saliva plays a crucial role in keeping your mouth healthy. It helps wash away food particles, neutralises acids, and prevents bacterial growth. Without enough saliva, you may experience a persistent dry feeling, cracked lips, or even dry skin around mouth. While dry mouth is common and can happen occasionally, persistent dryness could indicate an underlying issue or certain health conditions.

Major Symptoms of Dry Mouth

Experiencing dry mouth symptoms can be more than just an occasional inconvenience. It may affect your daily life, from eating to speaking. Below are some of the common symptoms that you may notice if you have a dry mouth:

  • Thick and stringy saliva – Your mouth may feel sticky, making it harder to swallow.

  • Bad breath – A lack of saliva allows bacteria to thrive, leading to persistent bad breath.

  • Difficulty speaking, chewing, and swallowing – Dryness in the mouth can make basic activities uncomfortable.

  • Dry or sore throat – You may feel constant dryness or irritation, sometimes extending to your throat.

  • Hoarseness – A dry mouth can impact your vocal cords, causing a raspy or hoarse voice.

  • Grooved or dry tongue – Your tongue may appear cracked, making it more sensitive.

  • Changes in your sense of taste – You might notice food tasting different or less flavourful.

  • Burning sensation – Some people with dry mouth experience a burning feeling in their mouth or tongue.

What Causes Dry Mouth

Your body’s systems work closely together. It means that your salivary glands can be affected by various factors, from health conditions to daily habits. While the primary cause of dry mouth is insufficient saliva production, several other factors can also contribute to this condition. Here are some of the most common dry mouth causes:

  • Dehydration – Anything from not drinking enough water to excessive caffeine intake can contribute to dehydration. Staying hydrated can help you reduce the dryness.

  • Medications – Many prescription and over-the-counter medications, including decongestants, can cause dry mouth as a side effect. This includes medicines for allergies, high blood pressure, depression, and pain relief.

  • Mouth breathing – Breathing through your mouth, especially while sleeping. It can dry out your oral tissues and worsen symptoms.

  • Smoking and alcohol consumption – Both tobacco and alcohol can reduce saliva flow, making dry mouth more severe.

  • Medical conditions – Certain health conditions, such as diabetes, HIV/AIDS, and autoimmune diseases like Sjogren’s syndrome, can impair saliva production and contribute to dry mouth cause.

  • Nerve damage – Head and neck injuries or surgeries can affect the nerves responsible for saliva production.

  • Ageing – As people age, saliva production naturally decreases, making dry mouth a common issue among older adults.

  • Cancer treatment – Radiotherapy and chemotherapy can damage salivary glands, leading to dry mouth. Radiation therapy to the head and neck can particularly impact the flow of saliva.

Identifying the major dry mouth and lips causes is important for finding the best treatment and maintaining good oral health. If symptoms persist, consulting a dental professional is recommended.

Risk Factors of Having a Dry Mouth

If dry mouth is not treated, it can lead to several problems. Saliva helps protect your teeth and gums, so without enough of it, you may experience tooth decay, gum disease, and bad breath. It can also make chewing, swallowing, and speaking difficult, which might lead to discomfort and poor nutrition. Some people may also develop a dry and sore throat, cracked lips, or mouth infections like oral thrush.

For those with health problems like diabetes, Alzheimer's disease, or HIV/AIDS, dry mouth can make symptoms worse and increase the risk of complications. If you have ongoing dry throat pain or discomfort, seeing a dentist or healthcare professional can help prevent more serious issues.

What to do For Dry Mouth at Night​?

Waking up with a dry mouth can be uncomfortable and may even disturb sleep. A dry mouth while sleeping is often caused by mouth breathing, dehydration, or the intake of certain medications. Identifying what causes dry mouth at night while sleeping can help in finding the right treatment or mouth dry remedy to relieve discomfort.

As an effective dry mouth at night treatment, try sipping water throughout the day and keeping a glass of water by your bedside. Using a humidifier in your bedroom may also add moisture to the air and prevent dry mouth while sleeping. Avoid caffeine, alcohol, and salty food before bed, as they may make dryness worse. Breathing through your nose instead of your mouth, chewing sugarless gum, or using dry mouth products like artificial saliva substitutes, sprays, and alcohol-free mouthwash may also help. If symptoms persist, consulting a doctor or dentist can provide further treatment options.

How to Treat Dry Mouth?

Effective dry mouth treatment often requires a combination of professional care and home remedies. Since dry mouth can lead to discomfort, bad breath, and even dental issues, it is important to take steps to keep your mouth hydrated and maintain good oral health.

Professional Dental Care

If dry mouth is becoming a constant struggle, a visit to the dentist might be the best step forward. They can suggest effective options for treating a dry mouth like fluoride treatments to keep your teeth strong or prescription mouth rinses that help boost saliva production. In some cases, they may even recommend medications to stimulate saliva flow. Regular dental check-ups are key to catching any issues early and keeping your mouth healthy.

At Home

Dealing with dry mouth at home does not have to be complicated. Simple habits like sipping water throughout the day and chewing sugar-free gum can help keep your mouth feeling more comfortable. Using a humidifier at night can also help add moisture to the air and make a big difference.

If you are struggling with dry skin around mouth, home remedies like coconut oil or aloe vera may help soothe and hydrate your skin. Also, try to cut back on caffeine and avoid alcohol-based mouthwashes—they can make dryness worse. Dentures may sometimes contribute to dryness, so keeping them clean and properly fitted is important. Gels, lozenges, and toothpaste designed for dry mouth relief can also provide additional comfort.

Steps to Prevent Dry Mouth

Preventing dry mouth is easier than you think. If you are wondering how to prevent dry mouth, try these simple changes to your daily routine to help keep your mouth hydrated and feeling fresh:

  • Stay hydrated – Drink plenty of water throughout the day to keep your mouth moist.

  • Chew sugar-free gum – It helps stimulate saliva production and keeps your mouth from feeling dry.

  • Use a humidifier – Adding moisture to the air at night can prevent dryness while you sleep.

  • Avoid alcohol and caffeine – These can dehydrate your body and make dry mouth worse.

  • Breathe through your nose – Mouth breathing can dry out your mouth, so try to keep your lips closed.

  • Choose the right mouthwash – Opt for an alcohol-free mouthwash to avoid further drying.

  • Eat moisture-rich foods – Fruits and vegetables with high water content, like cucumbers and watermelon, may help. Avoid acidic food and beverages like soft drinks. 

When to Visit a Dental Professional 

If home remedies and over-the-counter treatments are not helping, it might be time to see a dentist. Consider making an appointment if:

  • Your dry mouth does not improve despite trying home remedies.

  • Eating becomes difficult due to dryness or discomfort.

  • Your sense of taste is affected for an extended period.

  • You suspect your medication is causing dry mouth.

  • You have signs of tooth decay, such as cavities or sensitivity.

  • Persistent bad breath does not go away even with good oral hygiene.

  • Mouth sores appear, making it painful to eat or talk.

  • You also have dry eyes, which could indicate an underlying health condition.

If any of these symptoms sound familiar and you have persistent dry mouth, a dental professional can help diagnose the cause and recommend the best treatment for relief. Regular dental check-ups are crucial for managing dry mouth. Make sure to brush and floss daily. If brushing after meals is not possible, rinse your mouth instead. Sip water frequently, as it can moisten your mouth and also act as a remedy for dry throat.

Dealing with dry mouth, or xerostomia, can be frustrating, especially when it starts affecting your daily life. Whether it is caused by dehydration, medications, or other health conditions, the good news is that there are ways to manage it. Simple habits like drinking more water, avoiding caffeine and alcohol, and using saliva-boosting products can make a big difference. But if the dryness just does not go away, a visit to a dental professional can help uncover the possible cause and find the right treatment.
