People typically aren’t terribly fond of bitter tastes, which means that having one constantly present in your mouth can be quite annoying. While this sensation is certainly unpleasant, it can also be a sign of an untreated oral infection that can lead to serious consequences if allowed to progress. If it is harmful germs causing this troublesome taste, you should see your dentist as soon as possible if you notice it. Here are a few reasons why you may have a persistent bitterness in your mouth.
What Can Cause A Bitter Taste in My Mouth?
There are several things that can cause a persistent bitter taste in your mouth, and not all of them are the result of infection. A few common culprits being a lingering bitter taste include:
Dry mouth
Also called xerostomia, dry mouth happens when the mouth does not receive enough saliva flow. Saliva plays a crucial role in cleaning the mouth and preventing the accumulation of bacteria, so dry mouth can allow these germs to multiply uninhibited. Dry mouth can cause a sticky, dry feeling as well as a bitter taste, and it can be caused by mouth breathing, nerve damage, certain medications, radiation therapy, chemotherapy, or pre-existing conditions such as diabetes. Drinking plenty of water can help dry mouth, but see a health professional if the problem persists.
Oral infections
Neglecting to practice proper oral hygiene can lead to infections that cause a persistent unpleasant taste. Issues that lead to this problem include gum disease, untreated tooth decay, or dental abscesses. These problems can usually be prevented with excellent oral hygiene that includes daily brushing, flossing, and antibacterial mouthwash. In some cases, a bitter taste can be a result of oral cancer, which your dentist will screen for during routine appointments.
Acid reflux or GERD
Acid reflux and gastroesophageal reflux disease (GERD) can cause a bitter taste in the mouth due to the contents of the stomach being forced back into the esophagus. This acid exposure can cause an unpleasant taste, and while acid reflux is usually temporary, GERD can be a long-lasting or chronic condition. These issues may be able to be treated with improved eating habits or antacids.
Nerve Damage
Since all of our senses involve nerves sending and receiving signals to and from the brain, the sense of taste can be altered by nerve damage. Conditions such as epilepsy, multiple sclerosis, Bell’s palsy, dementia, brain tumors, and head injuries can alter the way nerves communicate with the brain, resulting in an unpleasant taste.
If you suspect that a persistent bitter taste in your mouth is caused by an oral infection, consult with your dentist immediately. This can prevent tooth loss, permanent damage to your gums and jawbone, and dangerous secondary infections like sepsis.
