Salty taste in the mouth

The salty taste in the mouth is a very unpleasant sensation, although in the vast majority of cases it is not serious. The first thing you should know is that it is not a disease in itself, but rather a symptom of various disorders, such as dehydration or gingivitis.

In some cases, the salty taste occurs only occasionally, while in others it lasts for several days. The most important thing is that you are very attentive to other symptoms to rule out any type of serious disease, such as a neurological disorder .

What are the causes of salty taste?


Dehydration is one of the most common causes of salty taste in the mouth , in both adults and children. It is known as such a massive loss of fluid in the body. It is common if you suffer from diarrhea or fever .

Remember that the salty taste is a symptom that indicates a significant dehydration, so it is important that you replace the lost fluid so as not to suffer serious complications . Of course, you should avoid those alcoholic or caffeinated beverages.

Drinking water is key. In addition, you can take natural juices and herbal teas.

Mouth injury

Any type of lesion in the mouth, regardless of its origin, inflames the tissue of the oral cavity , including the tongue. Thus, you may not be able to experience the sensation of taste.

However, in some cases, inflammation and irritation of the tissue can also cause taste alterations , resulting in a metallic taste or a salty taste in the mouth.

This can happen if, for example, you chew very hard food or the prosthesis is not adequate.

Acid reflux

Salty taste can be a symptom of acid reflux . It is a disorder that occurs when stomach acids enter the esophagus.

Other symptoms of this disorder are: heartburn, constant vomiting , nausea, cough and weight loss for no apparent reason.


There are many medications that greatly reduce salivary flow, causing the lips to become dry and a salty taste to appear in the mouth . The sensation in the vast majority of cases is very unpleasant.

In this case, it is best that you go to the doctor to tell him what is happening. Whenever possible, he will recommend replacing the medication .

It should not be forgotten that saliva fulfills essential functions in the mouth, which is why it is important to maintain an adequate salivary flow.

Tears and nasal secretions

Surely when you cry you feel a salty taste in your mouth. This has a very simple explanation: tears are salty and when you cry, they run down your face until they reach the back of your mouth. There is no possible treatment for this disorder, only prevention.

Something very similar happens with nasal secretions . When there is mucus in the nostrils, the salty taste is very common. This happens when you have a cold.

Nutritional deficit

Nutritional deficiency is a common cause of a salty taste in the mouth. It is accompanied by other symptoms such as tiredness, fatigue , weakness, numbness and tingling in the hands …

The most common deficit that causes this taste alteration is vitamin B-12 and vitamin C deficiency . Therefore, it is essential to follow a healthy and balanced diet, which includes foods rich in these nutrients.

Treatments: chemotherapy and radiation therapy

Chemotherapy and radiation therapy are the two most common treatments in the fight against cancer . One of the main side effects is the decreased flow of saliva, which leads to an alteration in taste. That is why a large number of patients who undergo this type of treatment notice a salty taste in their mouth.


In addition to the above alterations, there are a series of diseases that can alter the sense of taste.

Neurological disorder

Many neurological alterations affect the perception of taste, giving rise to different sensations, such as the salty taste. Although this is not the most common cause, it is important to rule it out.

Hormonal disturbances

Many women experience a salty taste in their mouth during pregnancy and menopause due to hormonal changes. In cambos cases the alteration of the taste buds is very common.


Gingivitis is one of the most common oral diseases , especially in adults. The mild form of gum disease is known as such, leading to symptoms such as irritation, inflammation, and redness.

Sjogren’s syndrome

The Sjogren’s Syndrome is a disorder that destroys the salivary glands, thus producing a dry. There is no specific treatment for the disease, although the doctor recommends constant hydration and, in some cases, the administration of artificial saliva.

When to go to the doctor?

Generally, the salty taste in your mouth gradually disappears over time if you develop certain healthy habits. However, if this alteration in taste persists over time, you should consult your doctor.

The vast majority of conditions that cause a salty taste in the mouth are easy to diagnose and are easy to treat.


As we have pointed out, the salty taste is not a disease in itself, but a symptom of a certain alteration. If this sensation recurs over time, it is recommended that you go to the doctor to establish a diagnosis and recommend the most appropriate treatment.

Once the doctor has evaluated your history, they will proceed to perform an oral exam . The main objective is to detect any type of infection in the mouth or teeth that may be causing bleeding.

Also, you can carry out a taste test to determine what is the cause. In this test, the patient’s response is checked with a series of chemicals.

Salty taste in the mouth in pregnancy

During the gestation period, certain hormones increase, such as progesterone or estrogen levels to promote the growth of the future newborn. With the increase in the hormonal level, there are also some changes in the body, especially during the first trimester. One of the most common is nausea, especially first thing in the morning.

The morning sickness characteristic of the first trimester of pregnancy cause sensory changes that cause salty taste in the mouth.

In some cases, these hormonal alterations generate a condition called digeusia, a change in taste.

There are many pregnant women who notice the salty taste in the mouth throughout the gestation period, especially first thing in the morning.

If you are also suffering from this problem, you do not have to worry because it is totally normal. However, if there are other symptoms that accompany this alteration in taste it is important that you consult your doctor.

How do taste buds work?

Remember that eating salty foods and drinks is one of the most common causes of a salty taste in your mouth. It is important that you understand how your taste buds work .

When you eat, you chew the food, so that it breaks down into small particles, which are partially dissolved by saliva in your mouth. When the saliva containing the particles of the food you have eaten comes into contact with the taste bud, the latter is stimulated and generates a series of electrical impulses.

As is logical, the stronger the flavor, the more stimulation generated is also. These impulses travel through the nerves to reach the taste centers of the brain .

Although the most important taste buds are on the tongue, there are also other areas such as the soft palate, the epiglottis, and the upper part of the esophagus.

The taste sensation makes eating more enjoyable for you. In addition, it helps the body to select some types of food. Another function that taste fulfills is to stimulate emotions and memories, which also play a very important role when choosing tastes and foods.

Once the taste sensation is generated , the food or drink is swallowed, but its taste continues in the mouth, gradually disappearing. In some cases it can last for long periods of time, until saliva or water wash it off.

How to avoid a salty taste in your mouth?

There are numerous home remedies to say goodbye to the salty taste in your mouth. They are very simple habits that you can incorporate into your routine.

The first and most important thing is to maintain good oral hygiene on a daily basis to avoid the accumulation of dental plaque and, thus, reduce the risk of diseases such as gingivitis or cavities. You should brush your teeth three times a day and, in addition, use dental floss and antibacterial oral mouthwash.

To avoid dehydration , you should drink plenty of water throughout the day. In adults, it is recommended to drink 2 liters of water daily, although the amount may be higher in summer or if you practice sports.

Of course, you should reduce your consumption of tobacco or alcohol as much as possible . And try to avoid those foods that are high in fat, or that are excessively spicy.

The salty taste in the mouth is an alteration suffered by millions of people around the world, and in the vast majority of cases it is not a cause for concern. However, if it recurs very frequently and is bothersome, you should see a doctor to find out its cause.
