Why do I have a bitter taste in my mouth?

A bitter or bad taste in the mouth can be a normal reaction to eating pungent or sour foods. However, when the taste lasts for a long time or happens unexpectedly, it can be concerning.

Taste is a complex sense that can be affected by many factors, including poor dental hygiene, dry mouth, or pregnancy.

A persistent altered taste in the mouth is known medically as dysgeusia. This taste is described as unpleasant and can last for a long time until the underlying cause is treated.

People with dysgeusia may experience a constant taste that they often describe as one of the following:

bitter, metallic, rancid or foul and salty.

The taste can be distracting, and may even make it hard to taste other things while eating or drinking. A person may still have the taste even after brushing their teeth. They may also experience other symptoms depending on the cause.

Causes

Many of the causes of a bitter taste in the mouth are not serious. However, the symptoms can be irritating and may interfere with a person’s regular diet or their enjoyment of daily life.

The following conditions can cause a bitter taste in the mouth:

Dry mouth

A dry mouth, also known as xerostomia, occurs when the mouth does not produce enough saliva. Because saliva helps reduce the bacteria in the mouth, having less saliva means that more bacteria can survive.

People with xerostomia feel a sticky, dry feeling in their mouth. This could be caused by factors such as medications, pre-existing disorders, or tobacco use. A person can also get dry mouth if they have a stuffy nose because breathing through the mouth can dry it out.

People with a persistently dry mouth should talk to their doctor for a proper diagnosis.

Dental issues

Poor dental hygiene can also cause a bitter taste in the mouth. It may also cause an increase in cavities, infections, and gum disease or gingivitis.

Many common dental issues can be avoided by regularly brushing and flossing the teeth. Some people may also find that using a tongue scraper helps to clear up some symptoms.

Using an antibacterial mouthwash in between brushing may help keep foul-tasting bacteria to a minimum. A range of mouthwash is available for purchase online.

Pregnancy

A bitter or metallic taste in the mouth is a common complaint during the first trimester of pregnancy.

The hormones in the body fluctuate during pregnancy. This variation can affect the senses, which can cause specific cravings and make some foods or smells seem disgusting.

Many people who are pregnant also notice a metallic, bitter, or tinny taste in their mouths. This can be annoying, but it usually goes away later in the pregnancy or after giving birth.

Burning mouth syndrome

Burning mouth syndrome is a condition that causes a burning sensation in the mouth. The feeling can vary, but many describe it as similar to eating spicy peppers. Alongside, some people may also experience a bitter or rancid taste in their mouth.

The symptoms of burning mouth syndrome may appear sporadically, but it can also be chronic and last for a long time.

Some people with the syndrome may have difficulty eating or drinking, while others may find that this relieves their symptoms.

Menopause

Women going through menopause may also experience a bitter taste in their mouth. This could be due to lower levels of estrogen in the body, which can lead to a secondary condition, such as burning mouth syndrome. It may also be due to a persistently dry mouth.

GERD or acid reflux

Gastroesophageal reflux disease (GERD) or acid reflux may be the source of an unwanted bitter taste in the mouth.

These conditions occur when the muscle or sphincter at the top of the stomach becomes weak and allows acid or bile to rise up into the food pipe.

GERD tends to irritate the food pipe, causing a burning sensation in the chest or abdomen. It can also bring about a foul or bitter taste in the mouth.

Outlook

Experiencing a bitter taste in the mouth is fairly common, and it should not be an immediate reason to be concerned.

Most bitter tastes are treatable, and a person may be able to manage this symptom while a doctor diagnoses the cause.

Once the cause is found and treatment begins, the taste buds should return to normal, and the bitter taste in the mouth should disappear.
