Most of us have encountered some form of mouth pain at some point in our lives, whether it was discomfort when eating, a painful tongue, or a burning sensation.

But what could be the source of the problem? The reasons for mouth pain are numerous and include a variety of things such as traumas, sores, as well as certain diseases.

Continue reading to learn about the many causes of mouth pain, also possible treatments, and when it's necessary to seek medical attention for mouth pain.

What could be causing the pain inside the mouth?

Pain in the mouth can occur in a variety of areas, including the following:

• the inside of the mouth
• inside of the cheeks
• back of the mouth
• gums
• tongue

We'll go over some of the most common causes of mouth pain, as well as how they can manifest themselves in different parts of your mouth.


It is possible that you will experience pain in the back of your mouth as a result of an accident. For instance, if you slip and fall, you may bite the lip or the sides of the cheeks to protect yourself. Pain and discomfort on the inside of the mouth may result as a result of this.
By biting into food which is extremely hot, you can also cause injury to your mouth. Burning sensations on the hard palate also referred to as the roof of the mouth, may result as a result of this.

Dry mouth

The salivary glands in your mouth create saliva, which helps to keep the interior of your mouth wet. A dry mouth might result when these glands do not produce enough saliva to quench one's thirst.

As a result, you may experience a parched mouth sensation, along with a rough tongue, mouth sores, as well as a burning sensation inside the mouth.

Dehydration is frequently cited as a contributing factor to dry mouth. Certain drugs, as well as underlying health conditions such as diabetes, might potentially contribute to the illness.

Canker sores

You may notice a canker sore on the inside of the cheeks, around the tongue, or even on the back of your tongue. It is a form of ulcer that is small and painful. They frequently manifest themselves as white lesions having a white border.

There are a variety of causes that might cause canker sores. Some of the most frequently encountered are as follows:

• food sensitivities
• vitamin deficiencies
• stress
• hormone fluctuations
• a viral infection

Some of the canker sores are quite painful, and you may experience tingling or burning sensations before they manifest themselves.

Herpes simplex virus

Cold sores are caused by the herpes simplex virus (HSV), which is a virus. When it comes to cold sores, although they are most commonly linked with the lips, if you are newly infected with virus, you may also develop painful lesions on the tongue, gums, or throat.

Before the lesions appear, you may experience a burning feeling associated with cold sores. Other signs and symptoms may include:

• a sore throat
• a fever
• muscle aches
• swollen lymph nodes

The severity of subsequent outbreaks is generally less severe than the severity of the initial outbreak.

Other infections

Painful sores or lesions within your mouth may be caused by a range of other bacterial and viral illnesses in addition to herpes simplex virus infection. Some of the most frequently encountered are as follows:
• chickenpox
• shingles
• infectious mononucleosis
• syphilis
• human immunodeficiency virus (HIV)
• hand, foot, and mouth disease

Mouth pain can be caused by a variety of factors, and you may have discomfort not only on the top, inside, or back of the mouth, but also around the tongue and gums.
You can take efforts to alleviate moderate mouth discomfort by using over-the-counter drugs and rinsing your mouth with saltwater. To be safe, don't put off seeing your doctor or dentist until you have severe, chronic, or reoccurring mouth discomfort.
