Bad Taste in Mouth

Bad Taste in Mouth: Causes & Home Remedies

Some foods may leave you with a bitter aftertaste in your mouth. It could go if you drink a lot of water and take good care of your mouth.

It’s normal to get a bitter aftertaste after ingesting bitter foods like chicory or black coffee.

No matter what you’re eating or drinking, having a persistently bitter taste in your tongue might be a sign of a number of medical disorders.

Everybody has occasionally had a foul taste in their mouth. According to estimates, 25% of the world’s population has poor breath, which frequently leaves a nasty aftertaste in the mouth. One of the most frequent causes is poor oral hygiene, but other factors include infections, sleep deprivation, and even consuming foods like garlic. Consult a doctor for further therapy if the bad taste doesn’t go away in a few days.

Signs And Symptoms

Patients with oral issues may experience symptoms like:

  • Red or swollen tissues in the mouth
  • Tooth sensitivity
  • Bad breath
  • Bleeding gums

People who also have a nasty taste in their mouth may also have the following symptoms:

  • Difficulty in eating
  • Diarrhea
  • Bad breath
  • Nausea
  • Vomiting
  • Loss of taste

The causes of these symptoms include oral thrush, hepatitis, respiratory infections, and acid reflux.


Oral thrush

Yeast infections, such as thrush, thrive in warm, wet environments like your mouth. Oral thrush may affect everyone, although it’s more common in infants, elderly individuals, and those with weakened immune systems.

White lumps, redness, stinging, or pain, difficulty swallowing, and dry mouth can all be symptoms of oral thrush.

Oral thrush may be avoided by regularly flossing, brushing, and washing your mouth. Additionally, make an effort to reduce your sugar intake because yeast loves it.

Even if you don’t have any other symptoms, you should always call your doctor if you notice white patches in your mouth.

Dry mouth

Dry mouth, also known as xerostomia, results from insufficient saliva production by the salivary glands. Your mouth may feel dry and sticky as a result.

Saliva aids in the removal of food particles from the mouth and slows the development of germs there. Lack of saliva can cause your mouth to become overgrown with germs and retain food, giving you an unpleasant taste.

Dry mouth can result from a number of factors, including:

mouth breathing due to a congested nose, nerve damage, cigarette usage, autoimmune diseases, diabetes, over-the-counter (OTC) drugs, and prescription drugs

Work with your doctor to identify the cause of your dry mouth. The majority of persons with dry mouth find relief through dietary modifications, drug dosage adjustments, and over-the-counter or prescribed mouth rinses.

Poor hygiene and dental problems

The most frequent causes of an unpleasant aftertaste are oral issues. Regularly brushing and flossing may prevent gingivitis, which can leave your mouth tasting terrible.

A terrible taste can also be brought on by dental issues including infections, abscesses, and even the eruption of wisdom teeth.

Additional indications of dental issues include:

foul breath, sensitive teeth, bleeding, red, or inflamed gums, and loose teeth

The majority of dental issues may be avoided by consistently cleaning and flossing your teeth. Additionally crucial is maintaining frequent cleanings and examinations with your dentist. For further defense, you may supplement your dental regimen with an antimicrobial mouthwash.


Taste buds might also change due to the fluctuating levels of the hormone estrogen during pregnancy. When pregnant, many women claim to have a metallic or bitter taste in their lips. After giving delivery or later in the pregnancy, this often goes away.

Acid reflux

When the lower esophageal sphincter weakens, food and stomach acid can travel from your stomach upward into your esophagus and mouth, causing acid reflux, often known as GERD.

Illnesses and infections

Your body naturally produces a protein manufactured by many cells in the body to stimulate and moderate inflammation whether you have a cold, sinus infection, or another sickness. The taste buds may also be impacted by this protein, increasing sensitivity to bitter flavors while you’re unwell.
