Red Spots in the Mouth Causes
Red spots in the mouth can have a variety of different causes, many of which are inflammatory in nature. Inflammation can occur from systemic diseases or environmental triggers that irritate the mucosal lining of the mouth. There are many different causes which can most easily be grouped into the following categories:
The mouth is the body's first line of protection against different pathogens and toxic substances, and as a result, it is exposed to many infectious causes of red spots in the mouth.
- Bacterial: There are various bacterial infections that are associated with red spots that appear in the mouth, especially the soft or hard palate. For example, streptococci (strep) is a group of bacteria that can result in symptoms such as a cough, sore throat, and fever in addition to the appearance of small, painless red spots in the mouth.
- Viral: Viral infections often result in an infectious double-hit to the body since they often infect both the structures of the upper respiratory tract such as the nose and sinuses as well as the mouth. Viral infections such as herpes and paramyxoviruses (the virus that causes measles) can cause clusters of small red spots in the mouth . Those related to measles are often painless and are called koplik spots, whereas herpes spots can become large blisters that can erupt and cause significant pain and discomfort. Often viral causes of red spots in the mouth are very contagious, so it is important to be careful and prevent not only infection but also spread .
- Fungal: There are certain fungi such as candida that have a predilection for infecting warm, damp areas of the body such as the mouth. Spots caused by fungi can range from red and patchy to creamy and white.
Many inflammatory conditions that result in the body attacking itself can also affect the mouth and cause injury and inflammation that results in red spots or sores.
- Systemic: Systemic autoimmune conditions that affect multiple body parts such as inflammatory bowel disease and lupus often have symptoms that affect the mouth.
- Dermatologic: Many dermatologic conditions can result in chronic, inflammatory rashes or lesions that prefer the mucosal linings of the body, including the mouth. Conditions such as lichen planus can cause red spots in the mouth that persist and are difficult to treat.
Environmental causes can be related to certain exposures or lifestyle habits.
- Diet: The mouth is in direct contact with food and liquids that may cause allergic reactions that result in red lesions in the mouth . Foods that seem to be particularly common allergens or irritants include those that are spicy or acidic like oranges, eggs, strawberries, and even chocolate. On the other hand, diets deficient in certain nutrients such as vitamin B12, folate or iron can also result in red spots or sores in the mouth.
- Drug use: Tobacco and alcohol can cause significant irritation of the mouth and its structures and even some types of cancer. In fact, tobacco products are heavily associated with oral cancer . Tobacco and alcohol can cause excess cell growth in the mucosal lining of the mouth due to chronic irritation and result in painful sores. Mouth sores are also a side effect of chemotherapy .
- Stress: Fatigue and emotional stress can also be a strong trigger for the development of red spots or sores in the mouth. Take note if you develop spots in your mouth during stressful times.

Cold sores (also called oral herpes or fever blisters), are viral infections of the mouth caused by the herpes virus type 1. You were probably infected very early in life as a child when an adult kissed you. The virus stays asleep (dormant) and causes infections every now and then after exposure to lots of sun or emotional/physical stress. It is contagious when an outbreak is happening, but treatment is limited unless you are immunocompromised.

2.Acute Lymphoblastic Leukemia
Acute Lymphoblastic Leukemia (ALL) is a cancer of the white blood cells. This disease most commonly affects children between the ages of 2-5 years, and is a much more rare disease in adults. People with this disease get sick very rapidly. First, they feel fatigue and dizziness, and eventually the disease leads to bone marrow failure.
Prognosis is highly variable and dependent on the individual, so a consultation from an oncologist is required.

4.Mouth and Throat Sores From Cancer Treatment
Mouth sores are a common side effect of cancer treatment (chemotherapy or radiation therapy). Some types of chemotherapy are more likely to cause this than others. Cancer treatments are used to kill the bad cancerous cells, but unfortunately they also affect healthy cells. The cells of the inner lining of your mouth, esophagus (the tube that carries food from the mouth to stomach) and stomach can get damaged too. This can result in symptoms like red areas or a burning feeling in the mouth, painful sores and painful or difficulty swallowing.
In most cases, mouth sores get better within a few days.
