The tongue plays a crucial role in detecting flavors. It can taste salty after consuming foods with high salt content. However, certain medical conditions can lead to a salty taste even if you haven't eaten salty foods. So, what causes the sensation of a salty mouth? Let's explore the reasons behind it.

Causes of a Salty Mouth

Dehydration

Dehydration is one of the reasons why your tongue may taste salty. Saliva naturally contains some salt, which is responsible for the salty flavor. When you're dehydrated, the concentration of salt in your saliva increases, resulting in a more noticeable salty taste.

Dry mouth

Dry mouth is often linked to dehydration, but it can also occur as a medical condition known as xerostomia. People with xerostomia may experience salty or bitter-tasting saliva, along with a dry sensation in the mouth, as if cotton balls are in it. This condition can result from medication side effects or smoking.

Postnasal drip

Postnasal drip occurs when mucus accumulates in the back of the throat. When this mucus mixes with saliva, it can cause a salty taste. Other symptoms that accompany postnasal drip include a congested or runny nose and trouble breathing.

Oral infections

Certain oral infections may contribute to a salty taste in the mouth or on the tongue, such as:

• Gingivitis, which is inflammation of the gums
• Periodontitis, an infection around the teeth that also inflames the gums
• Oral thrush, a fungal buildup in the mouth

Gastroesofageal reflux disease (GERD)

GERD, also known as acid reflux, occurs when stomach acid travels back up into the esophagus. This happens because the lower valve between the stomach and esophagus weakens, allowing acid to escape.

This condition can cause heartburn and has been shown to impact taste, particularly salty flavors.

Other causes

Apart from the above, several other factors may cause a salty mouth, including:

• Zinc or vitamin B12 deficiencies
• Exposure to radiation therapy
• Side effects of medications
• Pregnancy
• Head injury, trauma, or surgery
• Hyperthyroidism
• Diabetes
• Kidney failure
• Liver failure
• Menopause

Treatment for a Salty Tongue or Mouth

The treatment for a salty tongue or mouth depends on its underlying cause. Conditions like dehydration or pregnancy often resolve on their own after rehydrating or giving birth. For other causes, seeking medical advice is essential for appropriate treatment.

Generally, you can manage a salty mouth or tongue by:

• Drinking plenty of water
• Practicing good oral hygiene, such as brushing, flossing, and using mouthwash
• Limiting alcohol and tobacco consumption
• Avoiding greasy or spicy foods
• Chewing gum
• Sucking on throat lozenges

If medications or treatments are responsible for your salty mouth, consult your doctor for alternative options. If the salty taste disrupts your daily comfort, it’s wise to consult a healthcare provider. You can also use the Ai Care app for consultations, available on both the App Store and Play Store.
