If after having tried all the mouthwashes in town you’re still asking yourself, “why do I have a bad taste in my mouth?” then it may be time to see a doctor. Strange tastes in your mouth could signal a wide range of things from poor oral hygiene to a sign of more serious illness like diabetes.
Suffering from Sour Mouth?
While morning breath or night of wine drinking can leave you with a sour taste in your mouth, usually after brushing your teeth and hydrating, the taste disappears. But if you’ve been experiencing an ongoing sour taste in your mouth, it could be anything from fluctuations in hormone levels due to pregnancy or the medications you’re taking.
However there are two causes of sour mouth that are very common; these are Gastroesophageal Reflux Disease (GERD), also known as “acid reflux,” and oral hygiene issues.
Acid reflux occurs when the stomach acid flows backward up the esophagus (the tube that carries our food from the mouth to the stomach), leaving its sufferers with heartburn and a bitter or sour taste in their mouths.
Lying down right after you eat and not letting your food properly digest while you are standing or at least sitting up can cause acid reflux. So can eating acidic and fried foods, garlic, onions, and chocolate.
A study published in NCBI found that 55 percent of GERD sufferers studied experienced bad breath, and concluded that halitosis is “significantly associated with the occurrence of heartburn…and sour taste.”
Another study found that decaying teeth and a high growth of oral bacteria associated with caries, poor oral hygiene and dry mouth were associated with a sour taste.
