Salty Taste In Mouth Doesn’t Have To Be Hard. Read These Tips

Salty Taste In Mouth

Salty Taste in Mouth – Symptoms

  • Salt may be accompanied by mouth metallic soap or bitter taste and can be extremely unpleasant.
  • Salty flavor more pronounced in the back of the mouth and throat can speak post nasal drip, GERD, respiratory infection, throat cancer.
  • Salty taste on the tip of the tongue and lips can speak on behalf of gingivitis or tooth problems.
  • Limited to or more pronounced on one side salty taste may be due to a disorder of the parotid gland, the problem of the teeth, ear infection, paralysis, Bell trigeminal neuralgia, herpes zoster (rash on the same side).


    Salty taste in the mouth may be accompanied by:

    • Dry mouth can be dehydration, medication side effects, Sjögren’s syndrome.
    • Burning in mouth may occur in vitamin B12 deficiency, herpes zoster, Sjögren’s syndrome.
    • White coating on the tongue may occur in GERD.
    • White spots in the mouth are usually from oral thrush (yeast overgrowth).
    • Bad breath may be due to poor mouth hygiene, gingivitis, postnasal drip, respiratory infection, chronic tonsillitis, throat cancer.
    • Throat pain may occur in flu, strep throat, infectious mononucleosis, throat cancer.

    Additional symptoms related to specific causes are described below.

    Salty Taste in Mouth – Causes

    1. Sweating

    Sweat is salty and can pour over your face to your lips.

    2. Dehydration

    Dehydration causes saltier saliva. Common causes of dehydration: drink enough, excessive sweating, regular consumption of alcohol, coffee and caffeinated beverages (energy drinks, soft drinks, tea), overuse of diuretics, laxatives, type 1 diabetes, renal disease.

    3. Tears, Eye Drops

    Tears are more or less salty. Tears are normally drain through the tear ducts, which begin as shaped openings sized dots at the corners of the inner and end eyes in the nasal cavity. From there tears can drain into the throat and thence in the mouth. Causes of increased tear production:

    • Crying
    • Eyes, irritated by hay fever or other allergy, eye inflammation or infection, contact lenses, eye surgery
    • Eye drops (may take six weeks after stopping using them for salty taste in mouth to disappear)
    • Tearing eye on one side may be due to blocked lacrimal canal (tears pour over the face toward the lips)

    4. Postnasal Drip

    Mucus from the nose can drain into the throat and mouth.

    • Swimming, diving in the sea
    • Infectious sinusitis
    • Sinus rinses
    • Allergic sinusitis may be triggered by pollens, dust mites, molds, tea tree oil (in shampoos, cosmetics, cleansers)
    • Nasal polyps
    • Nosebleeds

    5. Toothpastes and Mouth Washes

    Taste buds can be damaged by:

    • Toothpaste with mint or whitening, or sodium lauryl sulfate (SLS)
    • Swallowing fluoridated toothpaste
    • Mouth washes with alcohol, mint, whitening
    • Breathing mints (impaired taste buds for 3-6 months)

    6. Dental Causes

    • Tooth cavity
    • Broken tooth
    • Dental work: tooth (especially wisdom tooth) extraction, tooth filling or crown, teeth cleaning

    7. Mouth Conditions

    • Poor mouth hygiene
    • Inflamed gums (gingivitis). Symptoms may include salty taste over the gums, reddened, swollen, tender, detached or easily bleeding gums.
    • Stones in salivary gland ducts (sialolithiasis). Symptom: pressing upon the parotid gland (in front and below the ear) may push salty saliva on the affected side.
    • Salivary gland infection (sialadenitis)
    • Oral thrush due to yeast overgrowth after therapy with antibiotics, steroids, chemotherapeutics or immunossuppresants, or in HIV/AIDS or other immunodeficiency. Symptom: whitish, removable spots (with underneath redness) in the mouth
    • Sjögren’s syndrome. Symptoms may include constant salty taste and dry mouth, itchy throat, difficulty swallowing, dry itchy eyes, dry skin, constipation, joint pains. Diagnosis: blood test.
    • Dry mouth syndrome
    • Burning mouth syndrome
    • Oral allergy syndrome
    • Chemical burn of the mouth. Symptoms: ulcers (acute burn), scars (chronic burn).

    8. Throat Conditions

    • Common cold, influenza
    • Strep throat
    • Spread of ear infection into the throat
    • Infectious mononucleosis. Symptoms: fever, enlarged lymph nodes in the groin, armpits, neck, sore throat.
    • Chronic tonsillitis (tonsil inflammation), tonsil stones. Symptoms: enlarged tonsils, bad breath, white excretions.
    • Tonsil removal (tonsillectomy)
    • Throat cancer. Common cause: smoking. Symptoms: bad breath, hoarseness, throat pain.

    9. Coughing Up Mucus from the Bronchi or Lungs

    • Acute bronchitis. Symptoms: chest pain during (dry or wet) coughing, sometimes following common cold or influenza, lasting few weeks.
    • Chronic bronchitis. Typical symptoms: a smoker coughs up yellow/green mucus, especially in the morning, no fever.
    • Bacterial pneumonia. Symptoms: high fever, difficulty breathing, coughing up mucus.
    • Tuberculosis. Symptoms: low-grade fever, feeling unwell, coughing up bloody mucus. Ethambutol and rifampin used in treatment can add to salty taste.
    • Asthma. Symptoms: difficulty breathing and wheezing after stress or exertion.
    • Cystic fibrosis, a genetic disease with frequent respiratory infections, thick salty mucus, salty skin, diarrhea.

    10. GERD (Gastroesophageal Reflux Disease)

    Anything which increases gastric acid secretion, increases alkaline (and therefore neutralize) the secretion of pancreatic juice, which is high in salt. During the reflux, both the acid and salt can flow into the mouth and cause heartburn (burning sensation behind the breastbone) and / or salty acid, white tongue. The common causes and triggers of gastric reflux:

    • Foods, like chocolate, citruses, vinegar, mints, caffeine, spices, alcohol, sugary foods, tomatoes, cucumbers, onions, berries
    • High protein diet
    • Smoking
    • Stress
    • Fish oil and cod liver oil supplements, conjugated linolenic acid (CLA) in supplement form or in Burn Fat “recovery drinks”
    • Helicobacter pylori infection. Symptoms may include excessive burping and bloating. Diagnosis is made by a breath or blood test or histological examination of a sample of gastric mucosa obtained during endoscopy. Treatment is with antibiotics.
    • Pancreatitis.

    Therapy includes removing the cause, antacids or acid lowering drugs, eradicating H. pylori, surgery. Note: an acid lowering drug containing omeprazol/sodium bicarbonate may cause salty taste.

    11. Bile Reflux

    Gallbladder issues may result in bile reflux – flow of the bile from the duodenum through the stomach and esophagus toward the mouth, resulting in a bitter and/or salty taste, hoarseness, nausea, vomiting bile. Causes:

    • Peptic ulcer. Symptoms: upper middle abdominal pain aggravated by eating.
    • Gastric surgery
    • Gallbladder removal (cholecystectomy)

    12. Dietary Causes

    • Ammonium chloride or “sal amoniac” as a food additive E510 in salty liquorice and other foods, and as a diuretic
    • Magnesium sulfate in low-sodium salt, food additives (magnesium diglutamate or E625)
    • Monosodium glutamate or MSG (E621)
    • Potassium chloride in low-sodium salt
    • Fluoridated water or water naturally high in fluoride

    13. Nutrient Deficiencies

    • Zinc deficiency. Causes include inadequate zinc intake (foods high in zinc are meat, seafood, eggs, legumes), zinc malabsorption (celiac and Crohn’s disease, chronic diarrhea), main symptoms are anorexia, fatigue and diarrhea. Diagnosis is by a blood test. Zinc supplements should help within a week time.
    • Vitamin B12 deficiency (pernicious anemia). Causes: autoimmune disease, vegetarian diet. Symptoms: paleness, fatigue, a smooth, red tongue. Vitamin B12 supplements should help in few weeks.

    Diagnosis of Salty Taste in Mouth

    Diagnosis can be made either after disappearing of salty taste after removing/changing suspected triggers (medications, toothpaste, etc.), or by testing for diseases known to cause salty taste.

    If you cannot identify the cause, you may visit a doctor for ears, nose and throat (ENT).

    Treatment of Salty Taste in Mouth

    Removing or treating the cause may treat salty taste. Some tips:

    • Lemonade without sugar or sugar-free gum may provide temporary relief.
    • Use non-whitening toothpaste and non-alcoholic mouthwash.
    • If you think you are dehydrated, drink sufficient amount of water and reduce amount of alcohol, tea, coffee in your diet.
    • If you have gastric reflux, avoid alcohol, smoking, caffeine, acidic foods and discuss with your doctor about the treatment possibilities.
