How to Get Rid of a Sour Taste in Your Mouth: 10 Tips

Having a constant sour or bitter taste in your mouth can be unpleasant and seem to come out of nowhere. This persistent taste sensation can diminish your appetite and quality of life. Fortunately, a sour mouth is often temporary and treatable with simple at-home remedies.

What Causes a Sour Taste in the Mouth?

A sour or bitter taste can arise for a few key reasons:

  • Bacterial overgrowth – Too much bacteria from poor oral hygiene or dry mouth allows sulfur gases to build up on the tongue. This creates a foul, eggy taste.
  • Acid reflux – Stomach acid backs up into the esophagus creating a bitter, sour taste. This is common with GERD.
  • Medications – Some prescriptions like antibiotics, blood pressure pills, and antidepressants can leave a metallic, bitter aftertaste.
  • Tobacco use – Smoking irritates taste buds and promotes bacteria growth, leading to a sour mouth.
  • Pregnancy – Hormonal changes and nausea during pregnancy can cause a sour or metallic taste.
  • Dental issues – Problems like gingivitis, periodontitis, or tooth decay allow bacteria buildup that tastes sour.

Identifying the root cause will help you find the right remedy. Here are 10 tips to help get rid of a sour mouth taste:

1. Brush Your Teeth and Use Mouthwash

Brushing your teeth twice a day removes plaque buildup and bacteria that contribute to sour taste. Using an antiseptic mouthwash kills bacteria lingering on your tongue and gums while freshening your breath.

  • Brush gently after meals and before bed using fluoride toothpaste.
  • Pay extra attention to the tongue and inner cheek area.
  • Use mouthwash once or twice a day after brushing, swishing for 30 seconds.
  • Choose alcohol-free mouthwash if you have a sensitive mouth.

2. Drink Plenty of Water

Dehydration allows bacteria and food particles to stagnate in your mouth. Drinking adequate water produces more saliva which helps wash away bacteria and acids.

  • Drink 8-10 glasses of water per day
  • Always have water with meals to aid digestion
  • Avoid sugary sodas and juices which can worsen mouth bacteria
  • Infuse water with fruits like lemon, lime, or strawberry for flavor

3. Use Baking Soda or Salt Water Rinses

Baking soda contains alkaline properties that neutralize acids responsible for sour taste. Saltwater rinses pull toxins from the tongue and kill microbes.

  • Make a paste with 1 tsp baking soda and water and brush gently.
  • Mix 1/2 tsp salt in 1 cup warm water and rinse mouth for 30 seconds.
  • Repeat baking soda or salt rinses 2-3 times per day.
  • These can also be used after meals to prevent a sour taste.

4. Avoid Certain Foods and Drinks

Some foods and beverages are notorious for causing sour mouth:

  • Onions, garlic, and spicy foods – contain sulfur compounds.
  • Coffee – is acidic and can dry out the mouth.
  • Soda – high sugar feeds oral bacteria.
  • Citrus fruits – contain acidic juices.
  • Tomato-based products – high in acidic citric acid.

Avoiding these items, especially at night, can help curb sour mouth. Eat more neutral fruits and vegetables like melon, apples, cucumbers, and greens.

5. Check Medications for Side Effects

Over 400 prescription and over-the-counter medications list taste alterations as potential side effects. These include:

  • Antibiotics – metallic/bitter taste.
  • Antihypertensives – bitter/salty taste.
  • Antidepressants – sourness, dry mouth.
  • Bronchodilators – unpleasant aftertaste.
  • NSAIDs – bitter or metallic taste.

Talk with your doctor about finding alternative meds or lowering dosages if your prescription causes a lasting sour, bitter, or metallic taste. Also, drink plenty of water with these medicines.

6. Use Sugar-Free Gum or Lozenges

Chewing gum or sucking on hard candies generates more saliva flow to wash away excess bacteria sitting on your tongue. The increased saliva also raises pH and neutralizes acid.

  • Choose sugar-free gums with xylitol.
  • Xylitol inhibits cavity-causing bacteria growth.
  • Mints or tart candies stimulate saliva without added sugar.
  • Don’t constantly suck on lozenges as this can promote tooth decay.

7. Don’t Smoke or Use Tobacco Products

Tobacco use is linked with gum disease, oral cancer, and increased bacterial growth – all culprits of sour mouth. Quitting smoking improves taste and overall oral health.

  • Ask your doctor for smoking cessation support.
  • Avoid secondhand smoke exposure.
  • Drink more water to help detoxify the body.
  • Have regular dental cleanings for plaque removal.

8. Visit Your Dentist

Your dentist can identify underlying causes of sour taste like infections, dry mouth, or gum disease. Professional cleanings also remove hardened plaque that regular brushing may miss.

  • Get cleanings every 6 months.
  • Ask about sour-taste remedies like tongue scraping or zinc supplements.
  • Have them inspect for signs of gingivitis, cavities, or oral thrush.
  • Discuss any prescription meds that may affect your mouth.

9. Practice Good Oral Hygiene

Poor oral hygiene allows foul-tasting bacteria to thrive. Developing better habits inhibits bacteria growth.

  • Brush the tongue with a soft-bristled brush to dislodge bacteria.
  • Floss daily to remove particles between teeth.
  • Replace your toothbrush every 3 months.
  • Avoid sharing utensils or drinking cups.

10. Make Dietary Changes

Certain dietary tweaks can improve gut health and create a less hospitable oral environment for bad bacteria.

  • Eat yogurt with active cultures to balance mouth bacteria.
  • Increase fiber intake to promote digestion and reduce sulfur gas.
  • Avoid heavy meals before bed – bacteria produce acids while you sleep.
  • Drink green tea to inhibit bacteria and freshen your breath

When to See a Doctor

Schedule an appointment with your physician or dentist if you have a persistent sour taste accompanied by:

  • Dry mouth or excessive thirst.
  • Hoarse voice or sore throat.
  • Unexplained weight loss.
  • Swollen glands lasting over 2 weeks.
  • White/red patches or sores in the mouth.
  • Jaw pain or tooth sensitivity.

These may indicate an underlying illness requiring further evaluation. A sour mouth is common but if home remedies don’t help within 1-2 weeks, seek professional guidance. Proper diagnosis is key to finding the right solution.


A sour, bitter, or metallic taste is an annoying but often temporary oral health issue with many DIY remedies. Proper oral hygiene, dietary changes, adequate hydration, and avoiding culprit foods can help rid your mouth of sourness. Pay attention to any medications that may impact taste. Seeking dental or medical care can identify any underlying conditions. Addressing poor oral health habits and treating related illnesses can go a long way toward improving your sense of taste.
