Sour Mouth Taste Causes, Treatment | Get Rid of Bitter Mouth Taste


Sour taste in the mouth


Causes of Mouth Sourness

  • Invariably, anaerobic bacteria produce a sulfur smelling sour taste and bad breath, that you may face in the morning. These bacteria multiply on the back of the tongue, so it’s likely that you can taste the sourness. Saliva breaks down the bad breath bacteria during the day, but, at night the saliva production is largely diminished and this allows the bacteria to grow unchecked, accumulating on the back of the tongue.
  • Posterior nasal drip is another cause for sour taste.
  • Acidity due to a reflux of the stomach contents causes extreme sourness

Getting rid of the sour taste

  • Ensuring good oral hygiene is the chief way of eliminating the sour taste.
    Brush your teeth twice  a day and make sure you scrape the tongue as well.
  • Increase your daily intake of vitamin C, i.e., step up the consumption of citric fruits, capsicum, tomatoes, mangoes, etc. this will improve oral health and boost the immune system.
  • Eat 5 fresh leaves of the holy basil daily. Basil freshens the mouth and drives away bad tastes.
  • Every morning use a fenugreek tea gargle to rinse the mouth. The tea is a decoction of fenugreek seeds in boiling water. Fenugreek is an exceptional anti-bacterial.

      The most probable cause can be hyperacidity. Also he should check his blood sugar level if he has not done in 2 months, so that the dose of the tablet can be adjusted. Sometimes certain drugs can also cause bad taste in mouth, if you feel so, talk to your doctor for a substitute. It can also be vitamin deficiency, bad oral hygiene. So talk to your doctor regarding it so that he can treat the cause accordingly. Often chewing basil leaves few times in a day reduces sour taste. Powder 1 clove and 1 cardamom. Eat it as a mouth freshener. 1 tsp of powdered gooseberry with water is also effective in treating bad taste in mouth, especially when it caused due to acidity.

    I have a bad taste in my mouth for the last 7 months. I had a cold on Christmas and a lot of phlegm. I still have some phlegm and I am wondering if this has something to do with it. I would not normally suffer with phlegm.
    I have taken different remedies and following good oral hygiene. It might be something I am eating. I have started taking raisins with my porridge in the morning. Can this be a problem? I would be grateful for any help with this.

Bitter taste in mouth has many other reasons such as acid reflux, bad oral hygiene, tooth decay etc. Salt water gargling is beneficial. Eating oranges and drinking lemon juice helps to wash of bitter taste in mouth. If the cause is acid reflux he should avoid spicy and fried food.
