If you detect a bitter taste in your mouth that is constant and does not go away, it is important that you put yourself in the hands of professionals to determine its causes. In order to ensure your oral health, we are going to help you identify the reasons why you have a bad taste in your mouth.

What is the reason for the bitter taste in the mouth? The truth is that there are many causes that can lead to this condition and in this article, we are going to analyse them in detail.

Why do I have a bitter taste in my mouth?

These are the main reasons why bitter taste in the mouth can occur. Keep in mind that this problem is often accompanied by halitosis or bad breath.

Hydration problems

Sometimes a bad taste in the mouth is caused by something as simple as poor hydration. If you don't drink enough water, a transient dry mouth is more likely to occur. In these cases, a bitter taste in the mouth is normal. Every day you should drink between 1.5 and 2 litres of water. This will ensure a much better overall health.


Xerostomia or dry mouth syndrome is a much more prevalent oral disease than you might expect. It is caused by a number of factors and causes serious dry mouth problems. What happens is that not enough saliva is produced to keep the mouth moist.

A decrease in saliva generation also leads to other oral health problems, such as an increase in the prevalence of dental caries or an increased risk of infectious disease, such as periodontitis or gingivitis.

It is very important to visit the dentist if you have a problem with dry mouth. In order to stop the pathology, we must determine the origin of xerostomia and remedy it as soon as possible.

Bad habits

Habits such as smoking can also be behind the bitter taste in the mouth. Smoking greatly affects the sense of taste. It is also an unhealthy habit that prevents an optimal lifestyle.

As far as oral health is concerned, tobacco is a great enemy, as in addition to causing serious damage it also masks the symptoms of more serious oral pathologies, such as periodontitis.

Incorrect oral hygiene

If you do not follow good oral hygiene habits, it is very likely that a bad taste in your mouth will be part of your daily life. What happens is that the bacteria that live in the mouth are not successfully eliminated, causing that strange taste sensation. In addition, poor oral hygiene is behind many of the most common mouth infections.

Remember to brush your teeth every day, between two and three times. In addition, you should follow a good brushing technique, use an optimal toothpaste and perform quality interdental hygiene tasks. If you have a dental irrigator you should use it, as it will help to improve the health of your teeth and gums.

If you wear orthodontics with braces, the irrigator will become your greatest ally when it comes to cleaning your teeth. Finish your routine with a good mouthwash, which will provide extra protection for your teeth.

Infections in the mouth

The presence of infections in the mouth generates a bitter taste in the mouth, as a result of oral bacteria. There are many infections that can occur in the oral cavity. Tooth decay, gingivitis, periodontitis, fungus in the mouth or viral infections can lead to a bad taste in the mouth.

Very common diseases, such as oral candidiasis, can be responsible for such conditions. Candidiasis is an oral condition caused by the presence of fungi in the mouth. Risk factors, such as the use of dentures, can hide behind this problem.

If you detect that there is a problem in your oral cavity, do not hesitate and visit your dentist.

Pharmacological treatments

Some pharmacological treatments can cause a bad taste in the mouth. If you are undergoing cancer treatments, such as chemotherapy or radiotherapy in the head area, you will have been informed of the possibility of a bitter taste in your mouth. Therefore, before starting cancer treatment, it is advisable to visit your dentist and have a full assessment beforehand.

As you can see, there are many factors that can cause a bitter taste in the mouth. Make an appointment with a doctor if you detect any oral problem that may be causing changes in your sense of taste. At least once a year you should have a quality oral check-up.
