How to fix waking up with a dry mouth?

Dry mouth (xerostomia) is the persistent dryness of the mouth, particularly between the teeth and in the back of the throat. People with xerostomia sometimes feel no control over their salivary glands and experience pain swallowing their mouth. Xerostomia can be caused by a dry lining of the mouth or a decrease in saliva production, leading to a dry mouth. A dentist will tell you that there are many causes for dry mouth, including smoking, certain medications, excessive sugar or caffeine intake, or an abnormality of the salivary glands.

Dry Mouth Symptoms:

There are several dry mouth symptoms and causes for the salivary gland not working properly and making your mouth dry. One is an infection, such as yeast or viral infection. The other symptoms include deficiency of saliva, which can occur because of a low saliva flow or other problems.The dentist suggests that dry mouth can also be caused by excessive or dry eating or drinking certain foods, such as candy, sticky or crunchy candy, or citrus juices, or eating a lot of sugary or salty snacks. Drinking water frequently can help to alleviate dry mouth.

Causes of Dry Mouth:


Research has shown that one of the biggest causes of dry mouth is xerostomia. When your breathing isn’t completely relaxed, and there is a dry, scratchy feeling in your mouth when you exhale, your lips are still wet. It can be a hard symptom to treat but consulting with a dentist; would become one that can be easily treated for dry mouth problems.

Dehydration of Mouth:

Dehydration is one of the most common causes of dry mouth. When you don’t have adequate liquids to quench your thirst, the cells in your mouth that produce saliva become damaged, which may cause a dry mouth.

Doctors recommend drinking between 6-8 glasses of water every day. You may require more water if you’ve been sick. If the weather is very hot, or if you’ve done exercise for a long time.

Without treatment, dehydration can cause serious problems. You may feel seizures, heat exhaustion, kidney issues. Sometimes even a life-threatening condition is called hypovolemic shock. Most adults can get better by drinking more fluids. In severe cases, you may be hospitalized to receive fluids and electrolytes intravenously.

Less Saliva Production:

Sliva, which flushes out bacteria, flushes out toxins from your body. Without properly flushing out toxins, the bacteria commonly found in your mouth begin to multiply and grow in an unhealthy number. These bacteria cause bad breath, sore throats, oral and many other symptoms.

Gum Disease:

The other symptoms of dry mouth and bad breaths are gum disease and dental decay. Once the protective mucous layer on your teeth is damaged, it’s not long before you begin to suffer from bad breath and other oral symptoms. The bacteria in your mouth cannot travel through this layer and cannot reach the parts of your body that need moisture. It causes the drying of your skin on the inside as well as your breath. Gum disease and dental decay can both lead to more serious conditions. If left untreated, they can also weaken your immune system and make you susceptible to infections.

Breathing Through Mouth:

Another common cause for dry mouth and bad breath is breathing through your mouth. Have you ever observed that when you are breathing through your mouth that your mouth is dry? 

Not only does this affect how effectively you can breathe, but the way your lungs breathe as well. When your lungs are deprived of proper oxygenation, it weakens them and makes it easier for bacteria to breed in the spaces between the tissues. It may cause serious medical conditions and should be addressed by a medical professional.

Certain drugs, including tranquilizers and sleeping pills, can contribute to dry mouth because they cause changes in breathing. Some drugs, such as alcohol, can dry the mouth by changing the rhythm of breathing. Medicines containing chlorpromazine and thiouridine, such as pentoxifylline and phenytoin, can dry the mouth by causing decreased salivation.


Extra use of medicines daily like medications for high blood pressure, depression and anxiety will cause the dryness of your mouth and often lead to many dental problems.


With the passing of age, many people will face dry mouth problems. The reasons older people get dry mouths are that their body cannot take sufficient nutrients, changes in the body’s immune system and poor health will affect their mouth.

Nerve Damage:

Any injury or surgery that leads to nerve damage of your head and neck can cause your mouth to dry.

Tobacco and Alcohol Use:

Smoking can cause coughing and increased breathing, leading to dry mouth. Also, drinking alcohol and smoking or chewing tobacco can increase dry mouth symptoms.

Recreational Drug Use:

Methamphetamine intake can cause severe dry mouth conditions and damage to teeth; a condition is also known as “meth mouth.” Marijuana consumption can also cause dryness of the mouth.

Health Complications:

Dry mouth can also be caused due to many other health conditions, like diabetes, stroke, yeast infection (thrush) in your Mouth or Alzheimer’s disease. Sometimes, autoimmune diseases, such as Sjogren’s syndrome or HIV/AIDS, cause your mouth to dry. Snoring and breathing with your open mouth can also contribute to drying your mouth.

Other Complications:If you don’t have enough saliva and have a dry mouth, this can cause:

  • Maximum plaque along with tooth loss and other gum diseases
  • Mouth and throat soreness
  • Yeast infection in your mouth causing thrushes
  • Sores or split skin at the sides of your mouth or cracked lips
  • Poor nutrition along having problems with chewing and swallowing

Home Remedies to Cure Dry Mouth:

What is Dry Mouth? If left unchecked, a dry mouth can drive you crazy. Your mouth will continuously feel dry unless you’re making enough saliva. Fortunately, several at-home remedies help a lot for dry mouth treatment. To avoid causing dry mouth, apply treatment such as staying properly hydrated, applying mouthwash, and various over-the-counter products.

Drink Plenty of Water:

One of the most common remedies for oral health issues associated with dry mouth and bad breath is to drink plenty of water. If you are experiencing any halitosis, drinking water can help to moisten your mouth.

Antiseptic Mouthwash for Oral Health:

Not all mouthwashes or different kinds of toothpaste contain healthy ingredients. To get the most benefits for your investment, choose a product that includes natural ingredients such as herbs and spices to enhance the effect and fight harmful bacteria and germs.

Lose Weight:

One of the best ways to treat dry mouth and bad breath is to lose weight. Many different types of medical treatments can help you shed a few pounds and ease any tension in your muscles. However, losing weight is the main symptom often accompanied by a dry mouth and bad breath. When you lose weight, you also relieve the stresses on your body, including the stresses that you place on your oral health.


One way to lose weight and relieve the symptoms of dry mouth and bad breath is to engage in high-intensity, energy-burning exercise. By elevating your heart rate for at least 45 minutes every day, you will increase your metabolism, which will create more heat in your body and produce more saliva.

Excessive Saliva Production:

The third most common remedy for bad breath and dry mouth is excessive saliva production. Saliva is responsible for cleaning the back of the throat and opening the trachea, while saliva also produces certain chemicals called xerostomia. Xerostomia is caused when there is not enough saliva in the mouth, causing food particles to get caught in the back of the throat, where they remain until washed out during swallowing.

Humidifier to Treat Dry Mouth:

Stress and overexertion are also symptoms that can cause dry mouth and teeth grinding. Regularly using products like humidifiers can reduce stress and improve your oral health. Using a humidifier is very important if you are prone to dry mouth due to work-related activities. Using a humidifier is especially beneficial during cold winter months, as the cold air tends to dry out your mouth even more. Dry mouth is more common in the wintertime when people are more likely to be out in the cold.

Cutout Sugary Foods and Drinks:

In some people, the symptoms of dry mouth are the increased consumption of sugary foods, cookies and drinks. The easiest way to combat this would be to cut these out of your diet. Many dentists recommend xerostomia to their patients who have xerostomia, or persistent dry mouth, due to increased sugar consumption. It is believed that sugary foods produce more saliva than other natural substances, which helps cure your dry mouth, maintain good oral health, and wash away food particles. Saliva contains chemicals that can kill bacteria in the mouth.

Improve Overall Oral Care:

A dry mouth may be both a symptom and a cause of poor oral hygiene. Improving oral routines could be a crucial trusted source to protecting the health of your mouth. It includes frequent flossing, fluoride toothpaste use, and mouthwash use.

Herbal Treatments:

Many herbs can help to activate saliva production and temporarily relieve dry mouth, among them:

  • The use of Aloe Vera leaves moisturizes the mouth. Using aloe vera juice is a great way to treat a dry mouth.
  • Ginger is a well-known herbal sialagogue. It means it helps to stimulate saliva production, which also helps to treat dry mouth. Ginger’s sialagogue effects are mentioned in many studies to treat dry mouth.
  • Hollyhock has a moisturizing action similar to aloe vera. Studies showed it helps to treat dry mouth with the help of Malva sylvestris, a close relative.
  • Marshmallow root is also an emollient and moisturizing plant like aloe vera. It’s popular in traditional herbalism. Many studies have shown it helped dry mouth with the help of Alcea digitata, a close relative.
  • Nopal cactus is a traditional food and also a medicine of Mexico. It is also called prickly pear cactus; it’s gaining popularity in the health industry. The nopal could improve dry mouth or hypo-salivation.
  • Spilanthes is a popular herb used for maintaining dental health. One of the best uses is a sialagogue for increasing salivation, which may help keep your mouth moist.

When Should I Seek Medical Help For Dry Mouth?

Having a dry mouth is indeed a serious issue. Sometimes it’s a sign that you’re a little bit dehydrated.

consult the doctor

  • If you observe, medicines are the cause. It’s best to discuss going off medicines before disconnecting their usage.
  • If you have symptoms of other conditions, which include:
  • type 2 diabetes
  • Parkinson’s disease
  • Kidney disease
  • Anxiety
  • Depression
  • Anemia
  • Nutrient deficiencies

How to Increase Saliva Production?

Certain foods can also stimulate the production of salivary glands, such as lemon, grapefruit, and oranges. Chewing basil helps stimulate saliva production. Gargling with Aloe vera helps as well. Products like Aloe vera gel also help soften the hard plaque on the teeth, loosen the teeth’ enamel. It would be best if you chewed aloe vera gum regularly to stimulate your salivary glands.

If you’ve suffered from a dry mouth due to poor breathing, then your breathing can be controlled by pursing your lips or biting your lower lip. It prevents your lips from closing. It is known as a mandibular advancement device or MAD. Other devices include chin gear for the adults, which hold the lower jaw forward and pull the tongue forward, and continuous positive air pressure (CPAP), which keeps the air passing through the mouth at a constant rate. Your dentist can recommend a treatment that will help with your current breathing problem. However, if you do not have any of the above devices, you can try simple exercises to open your airways.

If you don’t mind consuming lots of liquids, chewing gum or using a saltwater gargle to eliminate the need to chew your food is a good alternative. These are effective ways to stop dry mouth caused by keeping your saliva flowing throughout the day. Saliva is the one thing that helps to break down and absorb nutrients in your mouth, so the less saliva produced, the fewer nutrients your body receives. Therefore, it is important to keep the salivary flow going as much as possible so that you can’t get mouth dryness, which is one of the major causes of many other oral diseases.
